| Abstract: | The operation parameters and cause of coking were analysed in heavy oil atalytic cracking unit.The measures including controlling the fractionator bottom temperature at 335℃,the the liquid level at 35%,increasing the circulation of oil slurry,improving the slurry system line-speed at above 1.0 m/s,contolling the residence time in the bottom of the fractionator less than 7.00 minutes,using scale inhibitor,running the oil slurry filtration,were used,the coking problem of the oil slurry system was solved. |
