低压脱甲烷塔乙烯损失影响因素分析及优化操作

FACTORS INFLUENCING ETHYLENE LOSS IN LOW-PRESSURE DEMETHANIZER AND THE OPTIMIZED OPERATION

结合茂名石化2号裂解装置生产实践,针对脱甲烷塔分析了操作温度、操作压力、CH4/H2比等对乙烯损失的影响,找出了影响乙烯损失的关键因素,并进行优化操作。

Combining with the production practice of the No.2 Ethylene Plant at SINOPEC Maoming Company, this article analyzes the factors influencing the ethylene loss of demethanizer including operating temperature, operating pressure and CH 4/H 2 ratio, finds out the key factors affecting the ethylene loss, and optimizes the operation.
