二氯乙烷的生产工艺技术进展

摘要

The progress in the production technology of ethylene dichloride is reviewed .The advantage and disadvantage of low temperature chlorination process ,medium temperature chlorination process ,high temperature chlorination process and oxygen chlorination method are analyzed .Characteristics of the process of dilute ethylene from FCC dry gas directly into dichloroethane chloride are analyzed .According to the composition characteristics of ethylene -rich gas from concentration of Maoming petrochemical company ,ethylene -rich gas is used through the technology of dilute ethylene dry gas producing dichloroethane .And corresponding technology improvement needs further re-searching .%概述了二氯乙烷生产工艺技术进展，分析比较了低温、中温和高温氯化工艺以及氧氯化法的优缺点，并研究了催化裂化干气稀乙烯直接氯化生产二氯乙烷的工艺特点。根据茂名石化干气提浓富乙烯气的组成特点，认为富乙烯气可采用干气稀乙烯制二氯乙烷工艺技术加以利用，相应工艺技术改进有待深入研究。
