EDC真空回收系统改造

摘要

In this paper,vacuum recovery system is designed to recovery EDC in heavy fractions,and feed preheating temperature,super-cooling temperature of tower top products and liquid feed position are analyzed to evaluate their relationships with the energy consumption of this system.%设计了真空回收系统,以回收重组分中的二氧乙烷(EDC).通过对进料预热温度、塔顶产品过冷温度、液相进料位置的分析,考察了它们与该系统能耗的关系.
