Cangzhou Dahua Juhai Branch’s new project approval

Recently, the environmental impact assessment of the 80,000 standard cubic meters per hour coal-to-raw raw material gas project of Juhai Branch of Cangzhou Dahua Co., Ltd. was approved.

It is reported that Juhai Branch of Cangzhou Dahua Co., Ltd. was established in March 2009. It is located in Cangzhou Lingang Economic and Technological Development Zone. It is one of the large-scale manufacturers of TDI, PC and bisphenol A in China. responsible company. The company currently has 50,000 tons/year TDI, 70,000 tons/year TDI, 60,000 tons/year DNT, 90,000 tons/year DNT, 135,000 tons/year nitric acid, 160,000 tons/year caustic soda, 100,000 tons/year One set of polycarbonate and 200,000 tons/year bisphenol A plant, mainly engaged in toluene diisocyanate (TDI), dinitrotoluene (DNT), hydrochloric acid, liquid chlorine, ion-exchange membrane caustic soda, high-purity hydrochloric acid, concentrated nitric acid, Production and sales of bisphenol A, PC and other products. The company's construction projects are TDI expansion and transformation projects with an annual output of 400,000 tons, nitric acid projects with an annual output of 300,000 tons, and expansion projects with an annual output of 100,000 tons of PC. All projects under construction have obtained environmental impact assessment approval.

In order to further build an industrial chain with strong competitiveness and ensure the upstream raw materials required by the polyurethane industry and polycarbonate industry, Juhai Branch of Cangzhou Dahua Co., Ltd. plans to invest 1,662,777,100 yuan to build 80,000 standard cubic meters/hour of crude raw materials gas project. The main construction of the project includes production equipment such as coal preparation, gasification, transformation and heat recovery, low-temperature methanol washing, gas separation, compression refrigeration, carbon dioxide compression, sulfur recovery, auxiliary production equipment such as oxygen removal and torch, circulating water, power substation, Rainwater tanks, cabinet rooms and other public works installations, drainage pumping stations, plant water supply and drainage, plant fire protection and other plant public systems, off-site projects such as carbon monoxide and hydrogen outside the factory, safety and environmental protection facilities, etc.

The raw material gas (CO+H2) produced by the project is all used in the company's downstream TDI device and PC device, not for sale; at the same time, the by-product steam is incorporated into the steam pipeline network of Cangzhou Dahua Juhai Branch, and the by-product concentrated sulfuric acid It is available for the isocyanate plant, ion-exchange membrane caustic soda plant and BPA plant of Juhai Branch, but not for sale.
