It is understood that the refining of coking crude benzene is one of the basic technologies of coal chemical industry. Shanxi Province is the province with the largest coking crude benzene production capacity in China. Coking crude benzene production accounts for about one-fifth of the country's crude coking production. Traditionally, the benzene process technology used in the acid-washing process has produced a large amount of unprocessable acid tar in the production process, which has seriously polluted the environment, resulting in low product quality and product yield, and has been banned by the state and banned within a time limit.
Taihua Group cooperated with Shanghai Baosteel Group and Zhejiang Meiyang Design Institute to use the crude benzene hydrogenation technology independently developed by China to build a 80,000-ton/year project for 300,000 tons/year coking crude benzene hydrogenation project. The successful commissioning of the device indicates that the domestic production of the coking crude benzene hydrogenation process technology is fully mature.
Coking crude benzene hydrogenation localization process equipment put into production
Recently, Shanxi Taihua Group's domestically produced 80,000 tons/year crude benzene hydrogenation unit and the entire plant supporting project have been successfully driven by a single batch. The project can produce 56,400 tons of pure benzene, 12,000 tons of toluene, and 0.3 tons of xylene each year, which can fundamentally solve the chronic diseases such as the pollution environment and low product quality that traditional pickling coking crude benzene refining technology cannot overcome.
