On the morning of November 20, Yankuang Group Rongxin Chemical Company held an environmental protection acceptance review meeting for the completion of the 400,000 tons coal-to-ethylene glycol and supporting equipment project.
The five-member review team went deep into the production sites of the 4,000-ton gasification unit, sewage treatment station, and salt separation crystallization project for on-site inspections. Listen carefully to Ji Wenpu, Secretary of the Party Branch and Executive Director, on work reports on sewage treatment, zero discharge of industrial wastewater, solid waste utilization and treatment, and environmental protection investment.
The review team affirmed and recognized the stable and good operation of Rongxin Chemical’s on-site environmental protection facilities and advanced environmental protection concepts, and reviewed the “Annual Production of 40t Coal to Ethylene Glycol and its Supporting Equipment” Propose modifications to the details of the “Environmental Protection Acceptance Report on Completion of the Project”.
After discussion, the review team believed that the design, construction, and trial operation of the project met the requirements of the “Regulations on Environmental Protection Management of Construction Projects” and unanimously agreed that the environmental protection of the second phase project passed the completion acceptance.
Relevant departments of ecological and environmental protection in Ordos City, Dalat Banner, and Development Zone, relevant team members of the company, deputy chief engineers, and heads of relevant functional departments and workshops attended the meeting.
Rongxin Chemical Phase II Coal-to-Ethylene Glycol Project with an annual output of 400,000 tons
It is understood that Rongxin Chemical II The phased project adopts a phased EPC construction model. The project has high-end design, advanced planning, and meticulous management. It took 23 months to complete various tasks such as civil construction, equipment installation, and unit commissioning, setting a new record for the construction of projects of the same scale in the coal chemical industry. .
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
