摘　　要：通过对国内同类三十万吨乙烯装置开车、生产中汽油分离塔产生的问题进行调研,讨论了开车阶段易产生液泛的原因。对总厂汽油分离塔提出增建中段外回流取热和将板式塔改为填料塔的建议,经实施后效果明显。The problems occurred during start-up and normal operating in gas separating columns of the imported 300,000 t/a ethylene plants in China are studied ,and causes of liquid flooding during start-up are discussed in this paper. Adding intermediate reflux and cooler and using packed column replaced plate column are suggested. The effect is evident in practice.
