Abstract

A treater regeneration system in a polyolefin production system, the treater regeneration system comprising an off-line treater receiving a first portion of a regenerating stream and regenerating a desiccant in the off-line treater to yield a regenerating effluent stream, where the regenerating stream comprises a regenerating medium, and where the regenerating effluent stream comprises the regenerating medium, water and an impurity; a decanter receiving at least a portion of the regenerating effluent stream to yield the regenerating stream and a water stream, wherein the water stream comprises the water; and a stripper receiving a second portion of the regenerating stream to yield an impurity stream and a process recycle stream, wherein the impurity stream comprises at least a portion of the impurity, and wherein the process recycle stream comprises the regenerating medium of the second portion of the regenerating stream.
