波纹管换热器在低温甲醇洗工艺中的应用

摘要

To optimize the process design package including the set up of two heat exchangers of corrugated tube type at the suction of lean methanol pump and this has improved the heat exchanging efficiency between the hot lean methanol and the cold rich resulted in a decrease of maintenance cost.After an arrangement of a group of corrugated-tube heat-exchangers at the pump suction the temperature of lean methanol introduced into the pump reduces to 70℃ and this reduces the difficulty in the pump manufacturing and raises the stability of pump running.%对工艺设计包进行优化,在贫甲醇泵进口设置2台换热器并采用波纹管式换热器,提高了热贫甲醇与冷富甲醇之间的换热效率,维护费用降低。泵进口放置一组波纹管式换热器后,进泵的贫甲醇温度降低至70℃,降低了泵的制造难度,提高了泵运行的稳定性。
