The application of CRC process in the FCC unit of Dagang Petrochemical Company was introduced. The results showed that the unit was operated normally and regulated flexibly after revamping . Under the condition of similar raw material performance, liquid and light oil yields increased by 1.99 and 0.31 percent points respectively, energy unit consumption [m(standard oil)/m(raw oil)] decreased by 6.73.The content of olefins and sulphur in gaso- line increased by 8.72 percent points and 27 mg/L respectively. The content of aromatics in- creased by 5.96 percent points. So after revamping, the product distribution was optimized , the product quality improved and saving energy effect was remarkable.
