System and Method for Processing Reactor Polymerization Effluent

A system for treating a polymerization reactor effluent stream from a polymerization reactor comprising:

• the polymerization reactor effluent stream, wherein the polymerization reactor effluent stream is fed from the polymerization reactor to a flash chamber;
• a polymer product stream, wherein the polymer product stream is recovered from the flash chamber;
• a flash gas stream, wherein the flash gas stream is fed from the flash chamber to a first column;
• a first column overhead stream, wherein the first column overhead stream is fluidicly communicated from the first column to an accumulator;
• an accumulator overhead stream, wherein the accumulator overhead stream is fed from the accumulator to a second column;
• a second column overhead stream, wherein the second column overhead stream substantially comprises ethylene;
• and
• a second column bottom stream, wherein the second column bottom stream is substantially free of olefins.
