The present invention relates to a system for removing a volatile catalyst poison from a liquid hydrocarbon feed to a polymerization process, the system comprising: a) a process vent originating from a polymerization process; b) a vent recovery system in fluid communication with the process vent, wherein the vent recovery system compresses the process vent to form a recycle gas; c) a stripper column, wherein the stripper column receives a first portion of the recycle gas and a fresh liquid hydrocarbon, and wherein a stripper column tail and a stripper vent gas exit the stripper column; and d) a liquid feed pump in fluid communication with the stripper column, wherein the liquid feed pump pressurizes a degassed liquid hydrocarbon comprising the stripper column tail.
