["本帖最后由 liaifeng 于 2218-8-5 17:21編集目前国内MTO装置已有余，装置的整体运行很平稳，但是也存在较多的问题，比如急冷水塔压差大，气体污水COD严重超标！请各位畅所欲言，出现问题和解决的一些办法，为大家的MTO清洁、高效生产做出指引！"

["急冷水固含量高，净化水油含量高，水洗塔压差高，水洗塔反应气出口温度高，催化剂跑损严重"

["急冷水固含量高，空冷一年四季得连续清洗，费用较大!烯烃分离采用急冷水作热源的换热器也要定期清洗！"

["水洗塔顶、反应三选后的产品气分析表经常出现问题使得反应定碳不好控制。反应中乙炔含量较高是什么原因？两个滑阀差压较高，不知道怎么回事。急冷水PH波动较大，不好控制。"

"甲醇制烯烃！说白了就是甲醇制乙烯、丙烯，副产一部分碳四、碳五！"

"还是还是经验不足啊，这些问题我都回答不了，哈哈"

"据说工况稳定时几乎不需要调整定碳。离线分析也都是24小时/次。只要定碳没问题，产品有问题那也是其他地方的问题。需要根据分析表频繁调整定碳吗？"
