Abstract

A feeding device for preparing a feed stream for a solution polymerization, comprising a feed vessel, the feed vessel comprising a top zone and a bottom zone; a feed outlet for withdrawing the feed stream, wherein the feed outlet is fluidly connected with the bottom zone; a waste outlet for withdrawing a waste vapor stream, wherein the waste outlet is fluidly connected with the top zone; an absorber positioned below the top zone; a first inlet for introducing a fresh liquid stream into or on top of the absorber, wherein the first inlet is fluidly connected with the absorber; a first heat exchanger positioned upstream of the first inlet for cooling the fresh liquid stream prior to_introducing the fresh liquid stream into or on top of the absorber; a second inlet for introducing a recycle liquid stream, wherein the second inlet is positioned below the first inlet; and a third inlet for introducing a recycle vapor stream, wherein the third inlet is positioned below the second inlet and above the feed outlet, wherein the feed vessel does not comprise a heat exchanger in the top zone.
