Hebei's first WSA acid plant to produce acid
The first WSA acid production process project in Hebei province was recently completed at the Coking Plant in the West District of Hebei Iron and Steel Group and the smooth production of acid. After the project is completed and put into production, it can produce 18,000 tons of concentrated sulfuric acid with a concentration of 98%, and 4,320 tons of intermediate pressure steam as a by-product. This will achieve zero emission of wastes and waste liquids and discharge of tail gas, achieving a profit of 18.86 million yuan.
This project is an energy-saving and emission-reduction project for the coke plant in the west area of ​​Handan Iron and Steel Co., Ltd. With a total investment of more than 40 million yuan, it is mainly equipped with WSA condensers, sulphuric acid coolers and acid pumps, all of which are imported from Topsøe in Denmark. Solvay's patented WSA acid production technology. With short process flow, less equipment and less investment, the waste heat boiler can maximize the use of the waste heat of the combustion gas, save energy, and increase the thermal efficiency of the entire plant. The process uses a relatively high activity of wet conversion catalyst, the conversion efficiency exceeds 99%; the quality of sulfuric acid meets the commercial grade sulfuric acid standard; the device does not produce waste and waste water, and the exhaust gas reaches the national environmental protection discharge standard.
