| Abstract: | In the No.1 FCC unit in SINOPEC Jinling Company,fiber membrane process has been applied to sweeten FCC gasoline.As cooper strip test of treated FCC gasoline failed,the causes of failure were analyzed and culprits were found to be higher hydrogen sulfide,element sulfur,polysulfide,etc.The gasoline has successfully passed the copper strip test after increasing water injected into fractionation column,stabilizing water wash cycle and applying gasoline pre-alkaline cleaning and optimization of operation,etc. |
