醋酸生产中2种尾气吸收装置的性能评价

Evaluation on Two Tail Gas Absorbing Devices in Acetic Acid Plant

对分别采用甲醇作为吸收剂和醋酸作为吸收剂的2种醋酸尾气处理装置进行了在工况稳定条件下吸收剂对碘甲烷吸收效果的比较,正常状态及事故状态下运行稳定性的讨论,对装置建设及运行成本进行了分析对比,并给出了选择建议。

The paper discusses absorbing effect of iodomethane from tail gas of acetic acid plant in two disposal plants which adopted different process,one with methanol as absorptive agent,another with acetic acid,the stabilities under normal operation and emergency conditions,compares the costs of construction and operation,and gives some selection suggestions.
