The purity of this project is provided by the factory qualified propylene step synthesis of acrylonitrile with propylene ammonia oxidation method, and then the reaction product in turn after quench tower (after the absorption reaction of ammonia and cooling), water absorption tower (product soluble in water, eliminate waste), extraction distilation separation (acrylonitrile and acetonitrile) and refined tower (refined products and by-products, such as hydrocyanic acid and acetonitrile) and other steps to complete the production of acrylonitrile.Propylene ammonia oxidation process with raw material was cheap, low production cost, the advantages of simple production process, so at home and abroad has become a main method of acrylonitrile production. So, this device adopts the fluidized bed propylene ammoxidation to acrylonitrile.
