Yanchang Petroleum Refining and Chemical Company's Oilfield Gas Chemical Technology Company succeeded in producing excellent grade 1,4-butanediol on November 19, and at 22:30 pm on December 29th, another good news-an annual output of 100,000 tons of B The glycol plant successfully completed the entire process and produced polyester-grade (superior) glycol products. At present, the purity of the product has reached 99.98% after comparison and analysis by laboratory tests, filling the gap in Yanchang Petroleum products and further extending the industrial chain.
It is reported that the company made persistent efforts after achieving the 1,4-butanediol plant smoothly through the entire process and producing high-quality products. It issued the sprint order for the test run of the glycol plant at the first time. All staff, craftsmen, designers, The start team, unite and cooperate, work together to tackle tough problems. Technical personnel analyze and optimize and adjust the feedback data in the trial production process in a timely manner. Safety supervision personnel comprehensively investigate and eliminate all kinds of hidden dangers. The front-line operators of the installation strengthen the patrol inspection, strictly control the process indicators, adhere to the safety red line, and ensure the production and operation of the installation. Work closely together to safely and efficiently promote the start-up of each production facility as planned.
The process route of the successfully produced ethylene glycol product adopts the first domestic French liquid-air methane washing separation technology and the first Shanghai Pujing Chemical oxalate method patented technology in the province to realize the classified and qualitative utilization of associated gas and increase the Angry added value. Ethylene glycol products are mainly used to make synthetic fibers such as polyester, which are the main raw materials for high-end textiles. They can also be used to produce antifreeze, lubricants, plasticizers, etc., and have a good market prospect.
