chambers 这边怎么翻译? the bottom of column 161t201 is divided into two chambers. the methanol from the trays is routed into the clean chamber (right chamber on &aa-p-ff 102), only. a part of the methanol collecting in this bottom chamber is pumped by the methanol injection pump 161p209 as injection methanol into the feedgas line upstream the feedgas coolers i and ii, 161e201 and 161e202. 161t201塔底分成两室,塔盘上来的甲醇仅进入净室(&aa-p-ff 102右室),底室中收集的部分甲醇用甲醇喷射泵161p209 作为喷射甲醇注入进气冷却器i 和 ii, 161e201与161e202的上游进气管线中。 这在rectisol很普遍的,就是为了防冻,在进气管线注入少量甲醇。查看更多
