甲醇合成塔压差大的原因分析及对策措施

Analysis of the Causes of Large Pressure Differential in Methanol Reactor and Countermeasures

采用国产甲醇合成催化剂替代进口的MK-121型催化剂后,出现了甲醇合成塔压差大的问题。对引起甲醇合成塔高压差的原因进行分析,通过采取优化操作、改变催化剂装填方式、优化催化剂规格参数等措施后,达到了降低动力蒸汽消耗、提高生产负荷的目的。

After using domestic methanol synthesis catalyst for methanol synthesis to replace imported MK-121type catalyst,there is a problem of large pressure differential in methanol reactor.The causes of large pressure differential in methanol reactor are analyzed,after taking measures,such as optimization operation,changing the catalyst loading method,optimizing catalyst specifications,etc.,the purpose of reducing power steam consumption and increasing production load has been achieved.
