On December 26, 2020, it was the first anniversary of Rongxin Chemical’s ethylene glycol production. In the one year since it was put into operation, it has completed nearly 300,000 tons of production, conducted more than 200 major and minor maintenance operations, and eliminated more than a thousand items that were deficient. The operation rate of environmental protection equipment is 100%. There was no disorderly discharge or excessive air pollutants.
Rongxin Chemical’s 400,000-ton coal-to-ethylene glycol production project uses three 4,000t/d multi-nozzle coal-water slurry gasifiers, CO conversion, low-temperature methanol washing, and CO cryogenic separation. , PSA hydrogen production, the second generation “WHB synthesis gas to ethylene glycol technology” jointly developed by China Wuhuan, Huashuo Technology Co., Ltd. and Hebi BMW Group. It was put into production on December 26, 2019. This year it has passed the 72-hour performance assessment. In November, it passed the completion environmental protection acceptance.
Rongxin Chemical Phase II Coal-to-Ethylene Glycol Project with an annual output of 400,000 tons
As understood , the second phase of the Rongxin Chemical Project adopts a phased EPC construction model. The project has high-point design, advanced planning, and meticulous management. It took 23 months to complete various tasks such as civil construction, equipment installation, and unit commissioning, creating an equal level in the coal chemical industry. A new record for large-scale project construction.
On December 28, 2019, the ethylene glycol unit was successfully put into operation at one time and produced qualified products. This is the first domestic ethylene glycol unit to successfully start up in the shortest time and produce qualified products at one time during the severe cold season in the north. New fastest record.
In the early morning of December 26, 2019, Ordos Nenghua Rongxin Chemical Phase II successfully fed 400,000 tons of coal-to-ethylene glycol at one time, and produced DMO (dimethyl oxalate) at 4:55 that day. ester).
The second phase of Rongxin Chemical’s polymethoxydimethyl ether project with an annual output of 400,000 tons of coal-to-ethylene glycol and 300,000 tons of ethylene glycol started construction in August 2017, with a total budgeted investment of 7.68 billion yuan, accounting for The land is about 1,268 acres, mainly using coal as raw material. Relying on the allocation and margin of coal-to-methanol resources in the first phase, it produces ethylene glycol, polymethoxydimethyl ether, etc. through processes such as gasification, transformation, purification, synthesis and distillation. Chemical products have extended the industrial chain and increased the added value of products. It is an important measure to improve the integrated development of the coal chemical industry and is also a necessary guarantee for the development of regional industrial clusters. </p
