Corrosion and Protection of Coal Chemical Gasification Unit
Coal chemical industry is a chemical process that converts coal into gas,liquid and solid fuel through a series of chemical processes using anthracite,bituminous coal and lignite as raw materials.Driven by the international interests of high oil and oil substitution and the background of national energy security,the technology of coal-to-olefins has been produced,and its process mainly includes coal gasification,transformation,low-temperature methanol washing,methanol synthesis,methanol to olefins and olefin separation.Among them,the gasification of coal is in the position of"leader"in the clean utilization of coal,which is an indispensable link in the modern coal chemical industry,which is mainly composed of coal slurry preparation unit,gasification unit and slag water treatment unit.
