Abstract: “SINOPEC closed coke handling system (S-CCHS)” has been successfully put into operation and passed the scientific and technological appraisal of SINOPEC Group, realizing the closed and clean operation of the whole process of petroleum coke treatment, and the problem of large content of fine coke appeared in the promotion process. The source of fine coke is analyzed, and the improvement measures are put forward. Finally, the calibration results achieves the expected purpose, which provides a reference for measures to reduce the content of fine coke in delayed coking unit.
