Catalytic cracking gasoline adsorption desulfurization technology(S Zorb)is a core technology for cleaning gasoline production.In recent years,issues such as transfer pipeline wear and leakage in S Zorb unit have become common difficulties in petrochemical industry.Since its commissioning in 2013,No.2 S Zorb unit has gone through frequent wears and leakages in transfer pipeline.Taking the case as research object,trials were performed on transfer pipeline such as corrosion risk assessment,gas solid two-phase flow state analysis and wear mechanism analysis.At the same time,the influence brought by ratio of bending radius to diameter of bend pipe and gas velocity on wears were discussed,which provide a reference for design optimization and operation reliability improvement of transfer pipeline.
