천술료변압흡부록을희정류미기장치운행중존재적문제——변화흡부장치재운행1년후출현산품기협대백색분말현상。경과시험모색，채용증가수흡수탑，용-35℃염수냉각적방안，사문제득도철저해결，개조후운행효과은정，병취득료일정적경제효익화배보효익。
Problems existing in operation of pressure swing adsorption unit for vinyl chloride rectif- ying tail gas, i.e. product gas entraining white powder after it ran for one year, were introduced. Through conducting experiments, it was found that adding a water absorption tower and adopting -35 ℃ cooling brine could solve the problems completely. After improvements were made, the operation was steady and could achieve some economic effects and environmental effects.
