Disclosed herein is a process comprising discharging a product stream comprising a polymer or interpolymer, a solvent, and hydrochloric acid from a reactor to an absorber; absorbing the hydrochloric acid from the product stream in the absorber; discharging the product stream now free of substantially all hydrochloric acid into a first heat exchanger; wherein the first heat exchanger is operable to condense the product stream from the absorber that is free of the hydrochloric acid; discharging condensate from the first heat exchanger to a collection drum, the collection drum being operable to receive the condensate from the first heat exchanger; separating the condensate in the collection drum into a sliding stream and a secondary stream; and discharging the sliding stream into a compressor; wherein the compressor is operable to pressurize the slide stream prior to recycling the slide stream to the absorber. 本文公开了一种方法，该方法包括将包含聚合物或互聚物、溶剂和盐酸的产物料流从反应器排放到吸收器中；在该吸收器中从该产物料流中吸收该盐酸；将现在不含基本上所有盐酸的该产物料流排放到第一热交换器中；其中该第一热交
