摘　　要：在工业清洗领域使用最多的卤代烃清洗剂,其中ODS(破坏臭氧层物质)清洗剂占有很大比重,但在使用中对人、被清洗物和环境会带来许多危害.为此,各种替代产品和替代技术应运而生.从经济、适用、安全、环保等方面综合评价,经过多年的探索、论证、比较和筛选,碳氢清洗剂作为替代品已得到广泛应用,尽管碳氢清洗剂有诸多优点,但与ODS清洗剂相比,其沸点高(150～190℃)、闪点低(50～70℃)、与被清洗的物质相容性好,使碳氢清洗剂的再生无法用原有工艺方法实现.本工艺方法的研究是采取硫酸萃取、静置分离、精馏的方法再生碳氢清洗剂,达到原有的品质重复利用,硫酸萃取剂蒸馏回收重复利用,达到资源化利用的目的.ODS（Ozone Depleting Substances） cleaning agent takes a large portion in halogenated cleaning agent,which is the most common cleaning agent.The use of halogenated cleaning agent has threatened human,object to be cleaned and the environment.As a substitute of halogenated cleaning agent,hydrocarbon cleaning agent has been widely used in the recent years.Compared with halogenated cleaning agent,hydrocarbon cleaning agent has higher boiling point 150~190 ℃and lower flashing point 50～70 ℃,which means the traditional cleaning agent recovery process are not suitable to recover hydrocarbon cleaning agent.This paper describes a new method to recover hydrocarbon cleaning agent.The recovery process is sulfuric acid extraction,clarification and distillation.Thus,the final product is qualified to be reused,and the sulfuric acid can also be reused.
