'We adhere to the idea of taking a small step and taking the long road to do a good job in differentiated production of high value-added products. We have built Tianjin Petrochemical into the environmental protection polyester industry base of Sinopec North China. Now it seems that we have such a foundation and strength. ' Wang Mingsong, deputy manager of Tianjin Petrochemical's Chemical Industry Department, said that this is very pleased.
At present, Tianjin Petrochemical has achieved normal production of environmentally friendly products, and its product quality indicators are in full compliance with the quality requirements of polyester products in the EU market. The Ministry of Chemical Industry will continue to take the differentiated road and play the green card as a weapon to expand market efficiency. Last year On the basis of turning losses into losses, we will continue to maintain a good momentum of production and operation. As of now, the two main units of the Ministry of Chemical Industry are all operating at high load and stability, with a total of 30,166 tons of differentiated products and an increase of more than one million yuan in profit.
Green products make old devices
'In the past, employees were looking forward to new investment projects and they wanted to stand up. Now they are not investing in order to survive; what was formerly good and what they are doing now. 'The director of the Polyester Workshop of the Ministry of Chemical Industry Yao Shusheng compares the employees' mentality to the past, 'is green production.' Let the workers see the vitality of the old device. '
The Tianjin Petrochemical polyester industrial chain was put into operation in 2000. Some of the products produced by the upstream units meet market demand, and some of them are used as raw materials for downstream units. In recent years, the competition in the polyester products market has intensified, and Tianjin Petrochemical has proposed to take a differentiated approach and fight green. Brand's innovative ideas.
'The 18-year-old device was built. The original device design is the route of conventional varieties. It is not difficult to take the differentiated route now. But we have the advantages of our own technology and high-quality products.' Wang Mingsong said with emotion, What's important is that during the 'Yongyong Chuang' symposium, employees changed their concepts, saw hope, and found a way out. '
On the basis of comprehensive analysis and demonstration, the Ministry of Chemical Industry conducted a study focusing on the quality requirements of the polyester series products in the EU market. They decided to aim at overseas markets without increasing investment, increase the added value of products with green environmental protection, and make up for a variety of products The lack of sex.
In September 2017, the polyester plant completely replaced the ruthenium-based catalyst with a titanium-based catalyst to open the 'green channel' of the downstream unit; on November 10, the new environmentally friendly product, hydroentangled staple fiber, went offline successfully and marked that Tianjin Petrochemical's polyester was short The textile industry environmental protection chain opened the whole process; at the beginning of February 2018, environmental friendly additives were successfully replaced, and polyester products were upgraded across the board, and the products fully met the quality requirements of the EU market.
'Tight-step push, see the move, there is always the feeling of living.' Wang Mingsong said. Small trial, batch, mass production of three-step plan, and ultimately resolve the technical problems affecting the stable production of the device, the key indicators Maintain stability, and ultimately achieve the goal of a superior product.
Since September 2017, Tianjin Petrochemical's exclusive production of environmentally friendly all-Titanium polyester chips have entered the North China market in full and exported to Denmark, Thailand, Japan and foreign markets for the first time.
Custom production opens the 'green' market
'We have very high viscosity requirements. Can you guys do it?' On the phone, the customer took a try and tossed an olive branch.
'No problem, please rest assured of our technology.' Li Shaoshan, a senior expert in the Ministry of Chemical Industry, is confident.
'You are willing to adjust the process for more than 2,000 tons of products?' Customer questioned.
'Trying to use it, I believe we will continue to cooperate.'
Therefore, from February 24 to March 5, for the first time, under the technological conditions of environment-friendly catalysts and additives, the polyester plant of District 14 of the Ministry of Chemical Industry began the production of high-value-added products—high-viscosity, stretch-bonded film-specific materials. The final indicators meet customer requirements and opened a prelude to happy cooperation.
“The current strict requirements for environmental protection in the country are ah. Sewage treatment has become a hurdle for many companies. Using our environmentally friendly products as raw materials helps manufacturers to further reduce production costs. They can not welcome it. The key is to use products well. Therefore, we are not afraid of trials and are not afraid of small quantities. We welcome customized products with special requirements. 'Li Shaoshan said.
They regard each special custom as an opportunity for improvement in production capacity, and as an in-depth market reach. In this process, they not only accumulated technical experience in producing environmentally friendly differentiated products, but also laid the foundation for future batch production. Solid foundation, at the same time, the efficiency of the device has been further improved.
Taking the export of polyester environmental protection products as an example, foreign customers tried feedback and were not satisfied with the environmental index of heavy metal content. After analysis and research by professionals of the Ministry of Chemical Industry, after the titanium catalyst replaced the ruthenium catalyst, a very small amount of heavy metals in the product came from Additives in the production process.
From December last year, they started to use environmentally friendly additives to replace the original additives. Because environmental additives have a nonlinear effect on the quality of the products, the workshop technicians take a small, pre-adjusted approach. Every time a certain percentage increase, the technicians will add With great monitoring efforts, the material residence time was calculated in advance, so that the process parameters were pre-adjusted to ensure the stability of the production process and product quality. It took two months to complete the replacement work.
Production and sales research and cooperation with the company
'This time the harvest was quite successful. We not only promoted environmentally friendly all-Titanium polyester chip products to our customers, but we also determined the key targets for functional and environmentally-friendly polyester products based on research results. It has now been listed as a key technology development project for the headquarters in 2018. Zhao Yongbing, Technical Quality Division of the Ministry of Chemical Industry said.
In November last year, Zhao Yongbing and three colleagues and the Tianjin Petrochemical Research Institute, Sales Manager of North China Tianjin Representative Office formed a production and sales research group to visit Shanghai, Guangdong users and traders, and communicated with the Shanghai Petrochemical counterparts. The market for the chemical product and its application were investigated. He was still very excited about this trip.
With the help of the 'production, research and development' platform, through 'going global, please come in', Tianjin Petrochemicals has increased its awareness and understanding of the market and continuously pushed polyester products to higher-end markets. In recent years, they have formed new ones. Product testing, technical exchange, after-sales service, product quality investigation, market research and re-development of closed-loop upgrade process, and establish cooperation with many universities, research institutes and similar companies in the system.
The production, sales, and research team has been fully involved in the exchange and service of market users in all aspects such as new products, new technology development, process optimization, product quality control, and product sales, storage and transportation, and has been recognized by users. Broaden your horizons, lay the foundation for further development of new polyester products.
Through investigation, we clearly felt that the market's attention and acceptance of environmentally friendly titanium-alloy-free polyester chips has improved significantly compared with 2016. 'Zhao Yongbing said that the market is a 'vane' and this information undoubtedly gives the main green card. 'Environmental protection' old device brings more power.
The production, sales and research team also brought another gratifying news: The potential market for low-melting polyester products is relatively large, and it is expected that the market capacity will be further enlarged. It is even more gratifying that cooperative companies have expressed their willingness to jointly develop low melting point polyester series products. For the Tianjin Petrochemical differentiated slice products provide test analysis, new trial spinning and other support.
It is reported that at present, Tianjin Petrochemical has been able to produce low-melting-point series of chips, and completed small-scale tests, pilot tests and spinning experiments for some products. The spinnability is good, and the device production scheme has been completed. New products with lower melting points have also been initially completed. Small test work.
