Wanhua Chemical Announces Environmental Assessment of the 400,000 Tons/Year PVC Project in Fujian

Wanhua Chemical (Fujian) Co.

Wanhua Chemical (Fujian) Co.
, Ltd.
intends to build a coal-based gasification unit area with the core of 400,000 tons / year MDI and 250,000 tons / year TDI (expansion) to provide MDI and TDI production needs The CO gas and H2 gas required for the synthesis of aniline ; plan to build a formaldehyde plant produced by the air oxidation method using methanol as the raw material; Southeast Electrochemical’s chlor-alkali plant will provide raw material chlorine and caustic soda for MDI/TDI production, and Southeast Electrochemical uses raw salt as the raw material.
As raw materials, ion-exchange membrane electrolysis is used to produce liquid chlorine and caustic soda solution, and the by-produced hydrogen is used as the raw material of aniline for comprehensive utilization.
MDI / TDI production process produces a large amount of by-product hydrogen chloride, in order to digest this part of the by-product hydrogen chloride, improve the comprehensive utilization of resources, Wanhua Fujian put forward supporting the construction of 40 Wandun / Year PVC production plant, the by-product HCl for Manufacture of polyvinyl chloride to form an idea of ​​comprehensive recycling of chlorine resources.
The main product scale of the project is VCM 400,000 t/a and PVC 400,000 t/aByproduct 25 % wt hydrochloric acid 3.
76 million T / A , and the new VCM apparatus of PVC device while supporting EDC tank, VCM tank, refrigeration station, cryogenic library, of PVC packaging plant, VCM / of PVC utility substations and other means And supporting facilities such as three waste treatment and environmental protection facilities.
The total investment of this project is 229856 million yuan.
