Abstract
A method including recovering a polymerization reactor effluent stream from one or more polymerization reactors, flashing the polymerization reactor effluent stream to form a flash gas stream, separating, in a first column, the flash gas stream into a first column overhead stream, a first column side stream, and a first column bottoms stream, separating the first column overhead stream into a gas stream and a liquid stream, and introducing a feed comprising the gas stream and at least a portion of the liquid stream to a second column to produce a second column overhead stream, a second column side stream, and a second column bottoms stream. A second column bottoms stream flow rate can comprise less than or equal to about 25 vol % of a total flow rate and a second column side stream flow rate can comprise greater than or equal to about 75 vol % the total flow rate.
