The first phase of the EIA has just arrived, and the second phase is here again!

The Biodegradable Materials Research Institute reported that the second phase of the upstream supporting industry chain project of biodegradable materials of Wuheng Chemical (Ningxia) Co.

In the previous first phase of the project, Wuheng Chemical has announced the EIA review and approval on January 12.

Overview of the second phase of the project

Project Name: Phase II Project of Upstream Supporting Industrial Chain Project of Biodegradable Materials

Total investment: 352 million yuan

Construction nature: new construction

Construction site: It is located in the reserved land for the factory of Wuheng Chemical (Ningxia) Co.

EIA agency: Ningxia Hui Autonomous Region Petrochemical Environmental Science Research Institute Co.

Project construction details

List of production scale and product plan of each device:

1,4-Butanediol unit: A new 70,000-ton/year 1,4-butanediol unit will be built, mainly building acetylenic unit and hydrogenation unit

Acetylene plant: Wuheng Chemical (Ningxia) Phase I project construction (2+2) * 13,000 tons/year acetylene plant (4 sets of acetylene generators, 2 open and 2 ready), using dry acetylene process, using calcium carbide as raw material, The crude acetylene gas is generated by the hydrolysis reaction of calcium carbide and water, which is sent to the 1,4-butanediol unit after purification

Formaldehyde plant: Wuheng Chemical (Ningxia) Phase I project builds 2x130,000 tons/year of formaldehyde (calculated at a formaldehyde concentration of 37wt%).

Hydrogen production from alcohol: The nominal production capacity of the methanol cracking hydrogen production unit in the first phase of Wuheng Chemical (Ningxia) project is 9500Nm3/h, the actual hydrogen consumption of the first phase of the project is 5338Nm3/h, the surplus hydrogen is 4162Nm3/h, and the hydrogen consumption of the second phase of the project is 5338Nm3/h.
