Recently, Xinjiang Tianye Phase I 600,000 tons / year ethylene glycol project designed by China Chemical Donghua Technology produced high-quality polyester-grade ethylene glycol products.
Recently, Xinjiang Tianye Phase I 600,000 tons / year ethylene glycol project designed by China Chemical Donghua Technology produced high-quality polyester-grade ethylene glycol products.
The purity of the product is as high as 99.
96% , which meets the national high-grade glycol standards and meets the highest requirements of the polyester industry for glycol indicators.
The smooth completion of the whole process of the project marked a major breakthrough in the plant-wide engineering design work undertaken by Donghua Technology and the EPC general contracting management of public auxiliary projects such as boilers, air separation and sewage .
The project covers an area of 2,200 acres and has a total investment of 7.
99 billion yuan.
The core process uses patented technology for producing ethylene glycol from high-chemical synthesis gas; the main equipment includes coal gasification, shifting, methanol washing, hydrogen / carbon monoxide separation, public and auxiliary projects, etc.
Carbonylation DMO synthesis and rectification, as well as oxalate hydrogenation to synthesize ethylene glycol and rectification, at the same time low-pressure co-production of methanol.
