Why are there two temperature displays on one tray?
Thread Content
From the drawings of the \"vapor separation unit\" I’ve seen, two trays are provided at tray number 57 of the deethanizer tower (with the feed coming in at tray number 10). What is the reason for this? Friends who are on the front line and have seen similar situations – could you let me know if these two instruments show a large temperature difference?
