翻译啊~~有两句话不会~~~？ 回复 3# jhyy19802003 start with a clean hydrocarbon adsorber. this may require some planning if the plant shutdown is scheduled. if a clean adsorber is not available, use one that has less than 12 hours of service and be careful not to warm the adsorber (thereby desorbing contaminants) during cold startup. this can be done by establishing a liquid level in the high‑pressure column before putting flow to the hydrocarbon absorbers. it can also be done by purging the operating adsorber to the atmosphere until liquid is being vented from the top of the adsorber indicating that it is completely filled with liquid. guard adsorber plants: the guard adsorber outlet valves will have been closed off on plant shutdown and shall remain closed after start-up until they have been checked to determine if the in-service adsorber is filled with liquid. this is to prevent desorbing of contaminants and permitting them to pass into the heat pump and column. 这两个中的hydrocarbon adsorber.与guard adsorber分别是什么啊？？最好这两句话能告诉我一下意思~~ 查看更多
