PetroChina Dushanzi Petrochemical Company said on the 24th that the company won the first place in the energy efficiency of the ethylene industry by virtue of its excellent energy consumption per unit product of 501.4 kg of standard oil per ton.
It is understood that the Ministry of Industry and Information Technology, together with the State Administration of Markets, recently released a list of 19 energy efficiency 'leaders' in 9 key energy-using industries such as steel, ethylene and cement in Beijing. Dushanzi Petrochemical Co., Ltd. won the ethylene Industry energy efficiency 'leaders' first place, Zhenhai refining, China National Sea Shell ranked second, three. At this point, the petrochemical company has been the sixth time in the ethylene industry energy efficiency 'leaders' first.
According to relevant persons of the petrochemical company, in 2017, the company strengthened benchmarking management, promoted energy management and control, and continuously improved the level of energy conservation and emission reduction. The company is aiming at the advanced industry, paying close attention to fine management, and strives to increase ethylene production and reduce energy consumption and consumption. The energy consumption per ton of ethylene is 592 kg of standard oil per ton, which is the only equipment of less than 600 kg of standard oil per ton of ethylene below 300,000 tons. The energy consumption of 1 million tons of ethylene is 497 kg of standard oil per ton, which has been maintained nationwide. Leading level. The monopoly petrochemical company actively promotes the lighter weight of ethylene raw materials, strengthens foreign cooperation through the support of headquarters, signs the contract for the introduction of Kazakhstan's light hydrocarbon resources, guides the regulation of the allocation of liquefied gas in Xinjiang, and accumulates the purchase of light hydrocarbons in oil fields, liquefied gas 85.3 10,000 tons, the proportion of ethylene raw materials is up to 25.5%. At the same time, the production operation of the equipment is optimized, the equipment is unplanned, and the abnormal cycle time is greatly reduced. The long-cycle operation of the cracking unit eliminates 121 operating bottlenecks and the operating cycle is extended by an average of 10 days. The 8 furnaces of millions of tons of ethylene plant were all put into operation for 151 days. In 2017, the annual production of ethylene was 1.322 million tons, ranking first in the country.
The petrochemical company has carried out energy conservation and consumption reduction work in a solid manner. In 2017, it completed 6 chemical cleaning of the convection section of the cracking furnace, and 4 sets of cracking furnace soot blower. The energy consumption of the 220,000 tons/year ethylene plant decreased by 3.99 units; The burning energy consumption per ton of ethylene plant decreased by 4.74 units year-on-year, maintaining the number one in the country. At the same time, the operation cycle of the flare gas recovery compressor was extended, the hydrogen network operation was optimized, the operation control of the product switching process of the polymerization device was strengthened, the material loss was reduced, and the whole was reduced. System energy consumption and material consumption. Since 2012, the Petroleum and Chemical Industry Federation has released a list of energy efficiency 'leaders' in the petrochemical industry every year, aiming to further call on petrochemical enterprises to 'learn faster than school, actively reduce consumption' and continuously improve energy efficiency. Promote advanced energy-saving technology and management experience, and continuously promote the energy-saving and consumption-reducing level of the petrochemical industry.
