这句话的翻译,大家帮忙指点下!? the only significant change made to the methanation unit since operations began is the addition of a bypass loop for the final reactor. this was done so that when production rates in the overall plant are decreased for reasons outside the methanation process, both sides of the methanation unit could be kept on-stream rather than having one side shut down. 投运以来,甲烷化装置仅有的一次较大改造是对末级反应器进行了旁通回路的安装。安装回路的原因是当甲烷化工艺由于外部原因而导致整个工厂的产量降低时,两侧的甲烷化装置都能够保持运行,而非一侧停车。 both sides 是指什么的两侧? 查看更多
