Can not say, can not tell, controversial, 'Pengzhou Petrochemical 'Growing like a symbol, not an ordinary petrochemical enterprise.
Pengzhou Petrochemical, a former chemical star project for the local government has created more than 30 billion yuan of investment performance, but now because of environmental pollution and other issues, riding a tiger hard ...
Pengzhou petrochemical overlooking
This article from the "Outlook Oriental Weekly", a deep analysis of Pengzhou Petrochemical investment and construction of the entire process, people are increasingly concerned about environmental protection today, this matter still has a lot of reference.
One day some eight years ago, Mu Guangfeng, formerly under the SEPA in charge of the SEPA EIA Division, came to Pengzhou, a town north of Chengdu, Sichuan Province, to examine the site of the Sichuan Petrochemical Base. At that time, Riverside, or an original village.
In January 2013, Mu Guangfeng told reporters: 'Is not it a joke? First, how can we build a source in the rivers? Second, how can we build it in the floodplain? How much do you have to pay?
'Tuojiang upstream zero kilometers!' Environmental Protection Engineering Environmental Engineering Assessment Center former chief engineer Mao Wenyong also shook his head .After many years, Mao Wenyong is still stuck in the throat: 'That is the land of abundance!'
Petrochemical development, why Pengzhou?
Pengzhou in Sichuan
Why build a large petrochemical base?
It is widely circulated that as early as 1988, Sichuan provincial party committee and government set foot on the important strategic position in the western part of Sichuan Province, making decisions on crude oil entering Sichuan and ethylene and refining projects in Sichuan to fill the gap between ethylene and oil refining in Sichuan and southwestern regions The industrial gap has allowed the industrial structure in the southwestern region to be transformed and upgraded.
In September 1991, the former State Development Planning Commission approved the Proposal for the 140,000 Tons / Year Ethylene Project in Sichuan Province, which was not implemented after the implementation of the ethylene raw materials was not implemented and the scale was too small.
As a long-cherished wish of Sichuan people, Sichuan provincial government ordered Chengdu to continue studying and actively creating conditions, and Sichuan NPC deputies repeatedly proposed the construction of large-scale petrochemical projects at the National Congress of the People's Republic of China. The state shall include the development plan for the "Seventh Five-Year Plan" and the "Eighth Five-Year Plan" and the proposed project plan for the Ninth Five-Year Plan and the Tenth Five-Year Plan.
Located in the middle and upper reaches of the Minjiang and Tuojiang valleys, Chengdu is home to the 'Land of Abundances' in Dujiangyan, the hinterland of the Chengdu Plain. However, due to the abundance of wind and cloud in the basins surrounded by mountains, the pollutants are not easily diffused.
As of 2013, there are 16.35 million people in Chengdu, and due to the rapid urbanization and industrialization, the carrying capacity of environmental resources has reached a bottleneck. Haze, water pollution and functional water scarcity have become increasingly prominent.
The floodplain which was selected as a reserve for chemical projects at the time belonged to Longfeng Town, Pengzhou City and was located in an important zone of the ecological barrier in the upper reaches of Chengdu Plain. The major controversies surrounding it all concentrated on the SEPA ' 2007'1 text.
This document said:
(I) Pengzhou site of Sichuan Petrochemical Base is located on the fan roof of the alluvial fan in the northern part of Chengdu. It is dominated by a well-permeable gravel pebble layer, with a shallow groundwater level and smooth flow of groundwater.
(B) of the pollutant water Tuo River polluting serious, there is no environmental capacity ...
(C) The base is located in the upper reaches of the main urban area of Chengdu, with a high frequency of static winds, weak dilution and dilution of pollutants and limited atmospheric environment capacity.
(4) 17 kinds of pollutants in the list of proposed projects of the base involving the list of priority pollutants in China's water environment ......
Pengzhou Petrochemical project built
At that time, we did not have any environmental awareness until after the Songhua River pollution incident in 2005, the petrochemical environmental problems were only taken seriously. "A consultant who once handled the project told reporters.
He told correspondents, site selection Pengzhou has its own historical reasons, the earliest is the first Lan Chengyu oil pipeline exports built in Pengzhou, then consider building ethylene project here.
As early as before the ethylene environmental assessment, about 2000 years ago, the consultative company for the Sichuan Petrochemical project to do the assessment report, invited the original Environmental Protection Agency experts to comment.At that time, environmental experts on the site Pengzhou expressed opposition, Sichuan Province Some leaders at the meeting also said that they should be "careful site selection."
However, not too many people really think of this as a serious issue. Some departments think that it is necessary to spend more for other places, "to be accountable for state-owned assets." In addition, Pengzhou City has made a lot of efforts to win the project. Many people Has done a lot of pre-investment, do not want to break some of the interests of the pattern has been divided, so in the end has not changed the site.
'Weak environmental protection' after the gun, there is no real power
If the site is not suitable, then how can this EIA pass? In the EIA process, the environmental protection department exactly what kind of role?
The "Strategic Environmental Assessment Report on the Development of Key Industries in Chengdu-Chongqing Economic Zone" compiled by the end of 2010 clarified the unreasonable location of the site in Pengzhou and its existing risks. Specifically, it stated: 'The layout of large-scale petrochemical bases in the source areas of the upper reaches of Tuojiang River, the development of petrochemical industrial zones, Not in conformity with the principle of general layout, there are a series of hidden dangers and risk of ecological environment, which will lead to compound water pollution including persistent organic pollutants, which will start from the source region of the upper reaches of Tuojiang River Liquid chemical leakage or wastewater accident Emissions will have a significant impact on water safety.The source area is generally a recharge area for the groundwater, and infiltration of rainwater with chemical pollutants in the chemical area will have a long-term cumulative effect on groundwater.
However, this strategic assessment that does not have any coercive force has just started its construction. Half of the petrochemical base has been under construction even after the EIA of the Petrochemical Base and the EIA of the 10-million-ton refinery project have been approved respectively.
'You'll read about the schizophrenias from these reports and approvals,' said one official who participated in the EIA of Pengzhou. He told reporters: 'Or, the disadvantaged and embarrassed environmental protection department has already done its best.' And that is why Pengzhou Petrochemical EIA approval process is the 'history of the most', and this is also the local government actively emphasize the term.
He told this reporter: 'The local government put EIA as a hard battle to fight, local officials with' political mission 'bubble in Beijing for many years, commonly known as' run the project'. No matter what conditions you mention, they are big package Promises can be done No matter what problems you put forward, the government will give policy measures as follows to ensure a deadline resolution: we just want to get the approval first and ignore these commitments completely.
In his opinion, the worst demonstrative effect of Pengzhou Petrochemical is that if such sites can be built with petrochemical plants, there will be no place for them to build in China and the EIA will eventually become a tool for making decisions.
The project entered the highly controversial stage of argument
From November 27 to November 29, 2006, the EIA Division and the Environmental Engineering Assessment Center under the former Environmental Protection Administration hosted the first technical appraisal meeting of the EIA of Petrochemical Base in Chengdu.
Also in those days, the supporting municipal project of Sichuan Petrochemical Base, the three-section section of Peony Avenue and the three-section section of Refining-Ethylene South Road in Pengzhou started to face the national public bidding.
This technical appraisal meeting is one of the most in-depth discussions among participating experts in the five reviews before and after the planning of the EIA and is also a relatively controversial one. Regarding the version of the EIA report of the base planning meeting, experts from the groundwater, surface water and atmosphere , Pollution prevention measures and total control, etc. The final conclusion is that 'Insufficient to support the environmental viability of the program' .
The former Environmental Protection Agency based on this technical assessment, on January 4, 2007 petrochemical base EIA approval made 'Suspended 'Decision.
After the announcement of "suspension" a few days later, on January 11, 2007, the Pengzhou Environmental Protection Bureau hosted the EIA hearing of the 10 million-ton refinery project of the petrochemical base on the ground. Until the planning and environmental impact assessment of the entire petrochemical base has not been approved, the compilation of the EIA report of the refining project is still proceeding steadily.
Chen Wenlong, deputy chief engineer of Chengda Engineering Company, a member of expert team of Sichuan Ethylene Project Team, and Liu Yongqi, a senior engineer of Sichuan Academy of Environmental Science who participated in the EIA report are still in accordance with the planning EIA report that has been "kicked back" , Highlighting the importance of refining projects to Chengdu and Pengzhou, portraying a beautiful picture of economic growth, an overview of the projects that are far from the final version, a high-tech, high-input The environmental protection measures have been guaranteed.
For example, on behalf of the military municipality Yi Zhengming 'refinery will not pollute the groundwater' problem, Liu Yongqi responded that the construction unit in strict anti-seepage measures based on the development of impermeable technical specifications' can ensure that does not cause groundwater pollution '
EIA report review team members, Liu Xiang, Tsinghua University groundwater experts told reporters: 'No one can make such a guarantee that made such a guarantee is useless.'
He said that the leakage of pollutants in petrochemical plants is basically unavoidable. The existing technologies can not be perfect and the groundwater pollution basically can not be eradicated. "It just means the degree of acceptability and prevention and control."
Another expert on assessment, Wang Hongqi, a groundwater expert at Beijing Normal University, told reporters after a lapse of 6 years: "I once described the severity of the risk of groundwater pollution in this place as an example. A bowl of water, or a pot of urine, you say it will not leak, but in the event of something, once the leak, it will wet your body ... ... '
However, at Pengzhou City and later EIA hearing, no experts told the public about such risks and did not disclose to the public the "emergency evacuation plan under the conditions of the largest credible accident in Sichuan Petrochemical Base" in the attachment to the EIA Report situation: When the largest credible accident occurred in the petrochemical base, the environmental risks of various toxic and hazardous substances such as benzene and hydrogen sulfide generated can reach a maximum of 21.2 square kilometers and require emergency evacuation of more than 130,000 people, including residents' Severe poisoning (death within a lethal radius of death) of 56,500 people.
Why can not another place?
When the State Environmental Protection Administration issued a notice of "suspension," it explicitly proposed that site selection and argument be carried out. In other words, this is also a disguised proposal that "This site is not suitable for some places.
However, both PetroChina's Sichuan Petrochemical Company and local governments are reluctant to make such concessions, and after several versions of the report were later "hit back", Petrochemicals continued to be petrochemicals through continual measures and commitment to environmental capacity Base landing Pengzhou manufacturing theory support.
'We do not know why we have to be in Pengzhou.' On February 28, 2013, Director of Investment Services of Chengdu Petrochemical Base Management Committee told reporters in the conference room of Chengdu Science and Technology Association: 'Only know From an environmental perspective, another alternative site, Jintang, is definitely better than Pengzhou, but in the end Pengzhou is better than Jintang: Pengzhou + measures better than Jintang.
Chengdu Petrochemical Base Management Committee, referred to as Base Management Committee, was established in 2006. It is the official department dispatched by the Chengdu Municipal Government in Pengzhou. It is responsible for administration of petrochemical bases, communication and coordination among various departments, investment promotion of petrochemical bases and other matters.
East told correspondents, Pengzhou as a petrochemical base site, not by Sichuan Province or Chengdu to call the shots, not by CNPC, not for the MEP's replacement proposal to change, not to turn to the county level Pengzhou to Decision.He learned that some managers of PetroChina Sichuan Petrochemical Company, have expressed 'in fact more willing to Jintang' opinion.If you move to Jintang, PetroChina can not spend so much now environmental investment.It is because you must not Pengzhou Therefore, measures should be taken in light of the environmental protection measures and standards at all costs, as long as both domestic and international energy are available.
Xiangdong said: 'The MEP was strongly inclined towards JT at the time, but there is certainly more sufficient reason for MEP to endorse Pengzhou's location because we do not have it.'
Why did you choose Pengzhou? The reason I heard at that time was that the land had been reserved for the development of industry for so long that you no longer need to build it and the local people did not do it. "At that time, he was Director of the Environmental Assessment Department of the State Environmental Protection Administration Handled to issue the project EIA approval Zhu Xingxiang told "Look Oriental Weekly."
At another time and place, Mou Guangfeng, the inspector of the EIA Department of the Ministry of Environmental Protection, told our correspondents: 'The reason for this is that the land has been frozen for a long time so as not to allow the development of the house, On the local people do not agree.
Zhu Xingxiang said he does not think there is anything wrong with Southwest China or Sichuan Province in laying out a petrochemical industry. He also dislikes extreme environmentalism in all petrochemical plants or "demonizing" petrochemical projects. However, from a reasonable site selection perspective, The best Golden Pavilion even do not build.First time, the former Environmental Protection Administration of the Tuo River Basin to be built in the project is very opposed to the project, because Tuojiang pollution has been very serious, there is no environmental capacity.But after continuous negotiations, the Sichuan provincial government in order to control the Tuojiang Several articles have promised to free up the environmental capacity, so although the approval documents are 'future tense', they can only trust the government's promise to make things that the promised future promise to meet the requirements. The 'feasible' given is also a viable one with preconditions, including cutting down all downstream industries and retaining only refinery and ethylene plants.
Finally, after repeated discussions and quarrels by expert teams, MEP 'Conditional 'Approved the petrochemical base of the planning EIA and project EIA.
Old routine expert explanation and advocacy
Like the massive positive publicity and explanations that have followed PX's demonization, experts and government officials are constantly explaining to the public about the project's environmental pollution problems. But when the masses choose not to believe it, everything becomes a hard-nosed ride ...
Huang Chuan-you, a member of Chengdu CPPCC and a water resource expert at Sichuan University, who was a member of the panel of reviewing experts, did not show obvious tendencies at the scene of the fierce review meeting. He also expressed the view that 'the background should be better for Jintang.'
In February 2013, when interviewed by him as a student at Sichuan University, he described "Oppositely," "Naive," "Do not Understand," and other descriptions of those who oppose Pengzhou.
Huang Chuan-You said that Tuojiang's environmental capacity has been greatly improved. "In the past, long-term non-compliance has now reached at least eight to 10 months." Pengzhou Petrochemical project, "a day discharge of wastewater standards only a few thousand square. Minjiang River water, with the Qijiang never mind. Minjiang down 400 flow inside it with only a few, it can be 'negligible'.
--- He stated these reasons, some do not correspond with the fact that the petrochemical base has been in the water shortage of Tuojiang River Jianjiang station to take water, the Minjiang River water transfer is only stuck on the surface of the paper.
In Huang Chuan-you's opinion, the emission of exhaust gas is also insignificant. "Even one-third, one-third, one-fifth of the street gas emissions are not reached!" He said that the so-called "street emissions" barbecue.
As an expert involved in the project review process throughout the entire process, Huang Chuan-you constantly explained and publicized the skeptics who are 'unknown truths' with the authority to truly understand the situation.
He said: 'Today I also said at the Political Consultative Conference that what you know about is indeed one-sided. From Chengdu citizens, I think the more you suffer, the worse. Why? The NDRC regarded this place as a circular economy and environment Friendly demonstration area to do, the crude oil came in, all the products went out, all the abandoned materials used as raw materials .Not now, Chengdu objected, put the refining and ethylene put here, and other downstream products, all Got rid of what is the concept of Chengdu? Dirty stupid live we have done, make money for others to take away.
Our correspondents also found during the investigation, some experts in the discussion of closed doors, including language logic, and after the door to the public's position (or not), sometimes very different.Our correspondents interviewed some of the experts Some said that 'do not know should not say' embarrassment, while others go beyond their professional boundaries, far from the problem.
'The petrochemical project has so far invested more than 300 billion.' 'A petrochemical base management official told Oriental Weekly, in which Chengdu Investment Group, which represents a tenth of a stake in Chengdu, has invested More than 30 billion in the project is not yet completed, the final accounts have not yet come out of the known petrochemical base has about 50 billion investment in environmental protection, and according to the initial budget, environmental investment is 2.785344 trillion yuan (including Pengzhou The government promised to demolish investment 73.5 million yuan), abrupt growth nearly doubled.If you do not build a downstream industry in Chengdu, then the original is the 'inverted' refining and 'a little back' of ethylene, not only PetroChina is not worthwhile, Chengdu Of the local finances also can not catch much benefit with the huge cost of both sides compared to the total loss.
After struggling for a project that initially created more than 30 billion investment results for the local government and made various Party Bs participating in the project earn pours, it is now facing a difficult situation to ride the tiger.
In the end what kind of pollution overlay effect?
Whether it is an EIA report from a petrochemical plant or an EIA report of a 10 million-tonne refinery project, it does not take into account the emission value that will be added to the "unstoppable downstream industries." These companies, which have been questioned by many experts for 'pollution that may be more difficult to control, After clustering, what kind of pollution overlay effect will be caused is still unknown.
Although MOEP 2007'332, approved on August 27, 2007, has already reiterated: 'There is an important groundwater environment in the base planning area that is fragile. There is no environmental capacity in Tuojiang, and poor diffusion of air pollution are important Therefore, the total production scale of petrochemical bases should be strictly limited to the planning target of 10 million tons / year refinery and 800,000 tons / year ethylene, no longer developing downstream products.
However, relying on refining 'leading', the petrochemical downstream industry chain theoretically is an extension of the geometric multiplication, is the most profitable part, but also do not need to get the approval of the Ministry of Environmental Protection.
According to the survey of correspondents, Pengzhou Petrochemical base in Sichuan Province has planned more than 10 local downstream industries projects, including investment 160,000 tons slurry thermal cracking project and 200,000 tons of ethylene oxide deep processing These are all heavily polluting, high-risk petrochemical projects.
Among them, Chengdu Jumbo Oil & Gas Co., Ltd. signed a slurry supply agreement with PetroChina through its petrochemical base management committee. Its oil and gas cracking unit for producing asphalt and diesel oil is in the immediate vicinity of the south side of PetroChina's plant area. Construction has been completed and PetroChina A little fire, you can follow the commissioning.
The project invested 50.76 million yuan, by three private equity partners to invest, by the Chengdu Institute of Ecology and Environment, which does not have the qualification of chemical, petrochemical and environmental assessment, to prepare the EIA report and approve it by Pengzhou Environmental Protection Bureau which does not have the approval status.
The environmental capacity promised has been hard to come by
It is undeniable that Chengdu has indeed made great efforts to tighten its environmental capacity for petrochemical bases, including the shutting down of sewage companies and the construction of new sewage treatment plants, etc. However, when the promised target is concretely implemented, it will inevitably be subject to objective reality .
The Pengzhou Petrochemical Refinery, originally planned to be put into trial operation on April 16, 2013, did not cause any fire in time. One of the most important reasons for this is that the Yangtze River Water Resources Commission of the Ministry of Water Resources has rejected the sewage treatment application for the petrochemical base because it was originally used as a demonstration of water resources When the local government promulgated a commitment to reduce emissions of Tuojiang, Minjiang River and other prerequisites, have failed to do so.
Not only did the water's capacity fail to reach the ignition conditions, the atmosphere also showed a deteriorating trend.
According to our daily average air quality report released by Chengdu Environmental Protection Bureau, at least, statistics show that the atmospheric capacity is not only not vacated but also deteriorated even in the districts and counties of Pengzhou City.
Taking March as a few years as an example, there were 14 days of mild pollution in March 2011 and all others were excellent. In March 2012, all of them were up to standard, excellent or good. In 2013, in line with the mass concentration of smog and haze in a large number of cities in mainland China, Chengdu also became the hardest hit by hazy weather. Pengzhou Prefecture was slightly polluted for 9 days in March, slightly polluted in 2 days and heavily polluted in 3 days. Among them, the pollution index on March 11 was 'exploded.'
In March 2012, Wang Wenbin, former director of Chengdu Environmental Protection Bureau, told our reporter that 'Pengzhou Petrochemical Environmental Impact Assessment has a very strict environmental assessment process and basically no pollution after its completion.' Prior to that, he systematically told reporters about the air currently facing Chengdu, Water and other aspects of the pressure.
'Our functional area has not yet reached the standard water has no environmental capacity, the air has no environmental capacity. The old standard of air we are only critical standards, control of the new standards implemented in 2013, inhalable particles tightened by 30%, I Reduce the annual 3%, ten years to achieve compliance. PM2.5 more difficult to manage ... ... 'Wang Wenbin said that the poor air diffusion conditions in Chengdu, had to rely on' wash the sky 'to ensure air compliance rate, that is, artificial rainfall, Fifty or sixty times a year.
Environmental capacity is not the next file, measures can immediately be freed up.According to Wang Wenbin introduction, processing capacity of 100,000 tons per day days back to the sewage treatment plant has been completed in 2007, but more than 4 years have passed, the actual The processing capacity of only 20,000 tons per day, because the pipe network is not complete, the sewage can not be received.
In the EIA report, the 100,000-tonne treatment capacity of Tin Shui Sewage Treatment Works is one of the safeguards that has been calculated to free up environmental capacity.
'Water is no longer carrying capacity and the atmosphere is not carrying capacity'
Wang Wenbin said that despite the great efforts in recent years, the regional water quality has improved, but still not be optimistic.Not only Tuojiang, Minjiang River water resources are also great pressure, Funanhe perennial water quality Difficult to meet the standard, there is no ecological flow at all. Now it is necessary to further expand the area of irrigation area in Dujiangyan, called 'Recreating a Dujiangyan'. "
'Dujiangyan Authority to protect agricultural irrigation water, as well as industrial water, domestic water, in its distribution of water inside, it is rarely considered ecological water.' Wang Wenbin repeatedly stressed: 'Water resources have no carrying capacity, the atmosphere is not Carrying capacity.
He also told correspondents at the same time, the next step, Chengdu, petrochemicals for the characteristics of pollutants to be monitored, the government has allocated more than 90 million yuan to purchase a number of special equipment for the petrochemical industry in Chengdu to conduct a comprehensive monitoring.
However, until February 2013, almost half a year after Wang Wenbin's death, he said the equipment has not really arrived yet.
Reporters from the petrochemical base management officials at the Department of the explanation is that Wang Wenbin was envisioned very 'ideal', would like to pass this time, the petrochemical base of a monitoring station, the Chengdu secondary monitoring stations and Pengzhou City, three In fact, the financial where to get so much money? The final implementation is in place nearly 20 million yuan of equipment, petrochemical base and the Chengdu Environmental Protection Agency also 'contention' for a while, and finally by the higher authorities to coordinate , 'Sentence' to the petrochemical base.
In June 2012, Wang Wenbin was admitted to hospital for 'depression' and died in September. Around him, his acquaintances and friends told the reporter: The environmental protection director's work pressure is indeed great.
Shortly after Wang Wenbin's death, an anti-corruption storm swept through Chengdu and also hit CNPC. Many officials who participated in or dominated the Sichuan Petrochemical Base project plunged into the capital. Following the death of former chief of Chengdu Workers' Investment Group, Dai Xiaoming, Li Chuncheng, former secretary of Chengdu Municipal Government, After Jiang Jiemin and others were successively investigated, in October 2013, PetroChina Sichuan Petrochemical Company held a low-profile coaching change and former general manager Li Dongsheng et al. Were also investigated.
Potential environmental risks, is the biggest problem
So far, the environmental impact assessment of our country has not included the evaluation of public health and health into the statutory EIA projects, but the United States and other countries have established standards.
In the report of the strategic EIA of Chengdu-Chongqing Economic Zone compiled by the Ministry of Environmental Protection, the health risk assessment model used by the U.S. Environmental Protection Agency (EPA) is cited. The watersheds in Chengdu and Chongqing from 2004 to 2008 can be used as drinking water sources Surface water quality in three categories and above) cross-sectional risk assessment of joint carcinogens, which pointed out: as a project of Tuojiang water pollutants in the five-year average risk rate of 2.37 multiplied by 10 negative 4 power, equivalent As a result, the EPA recommended 2.37 times the maximum acceptable risk level and has already presented a high health risk of drinking water.
It is noteworthy that this is still in accordance with the national surface water quality standards 'standard' section of the water calculation, at the same time, there are many sections of Tuo River water quality is difficult to achieve long-term standard, or even inferior 5. Strategic EIA report states: Chemical, petroleum refining, light industry, non-ferrous metals mining and smelting, etc. which are mainly developed in the region will result in the above chemical carcinogens emission increase, which has a superposition effect on the health risks of drinking water.
Thousands of tons of oil refining 13 sets of combined devices, combined with 800,000 tons of ethylene 9 sets of joint devices, and gradually launched the downstream industries, what will bring to the Chengdu Plain what kind of impact or threat?
In the atmosphere, according to the EIA report of the final version of the 10-million-ton refinery project, out of the total emissions of petrochemical plants including refineries, ethylene plants and thermal power plants under normal production, the sulfur dioxide emissions were 2454.7 tons / year and the nitrogen oxides were 4101.23 Year, soot is 502.1 tons / year, dust is 248.68 tons / year, non-methane total hydrocarbons is 13662.12 tons / year, benzene is 270.992 tons / year, toluene is 84.47 tons / year, xylene is 154.768 tons / year, Methanol 85.78 tons / year, hydrogen sulphide 7.6736 tons / year, ammonia 10.92 tons / year because there is an adjustment later, and the abolition of phenol acetone, bisphenol A and acrylic acid and ester three sets of devices, the final displacement The data has changed a bit.
In order to free up air capacity for Pengzhou Petrochemical Project, Chengdu has promised to shut down 66 enterprises. These enterprises basically rely mainly on small brick factories and paper mills. The major types of capacity to be released are sulfur dioxide and dust, which can not reduce the petrochemical characteristics Contaminants, especially some highly toxic and carcinogenic substances, such as benzene that is mainly organized and unorganized by continuous reforming-aromatics extraction units.
According to the EIA report of the 10-million-tonne refinery project, the discharge of waste water from petrochemical plants reached 3,522,600 tons per year after reuse and reduction, of which not only 211.36 tons of chemical oxygen demand (COD), but also ammonia nitrogen 52.84 tons, as well as 17.62 tons of petroleum, 3.52 tons of sulfide, 1.76 tons of volatile phenol and total cyanide compounds, 0.35 tons of benzene and toluene and 1.41 tons of xylene respectively. Of the measures, but also based on the three types of surface water to meet the requirements of COD and total nitrogen and ammonia emissions reduction control, the characteristics of pollutants and no effective means of reduction ...
Pengzhou Petrochemical, is still an awkward existence.
Written in the last:
Regardless of environmental supervision, or safety inspection, the starting point is for the people to live and work in peace and the work of seven friends and safety considerations.As ordinary chemical workers and business owners, the most hope is that the government or policy in the specific implementation To be specific to specific issues, across the board wrong, do not pay attention to environmental issues and pay more attention to performance more wrong, no matter what, can not sacrifice the lives and health of the people for the price.
