摘　　要：This article refers to the commercial test for application of thepolymerization inhibition tech-nology developed by the Research Institute of Petroleum Processing (RIPP) in the prefractionation systemof the pyrogasoline hydrotreating unit at the Olefin Plant of Qilu Petrochemical Company. During thecommercial test the operation of the C9+ removal tower, the de-pentanizer tower and its reflux line, productdelivery line, reflux drum, condenser, and reboiler of the prefractionation system that were susceptible tofouling and blocking went smoothly and the run cycle was significantly extended. The amount of foulingwas apparently lower than what was before the said commercial test. The fouling was loose and soft, andcould be easily cleaned. Test results have shown that this technology can effectively suppress the polymer-ization and fouling of active C5 diolefins existing in the pyrogasoline hydrotreating/prefractionation system,and can extend the run cycle of the process unit.
