Processing NH3 acid gas in a sulphur recovery unit. The feasability and economics of a two-stage sour water stripper with an SRU for NH3 contents of 25% and higher are discussed. Today's refineries are processing crude slates with higher sulphur and nitrogen contents. Some of these crude slates have such high nitrogen contents that the feed to the sulphur recovery unit (SRU) contains a far higher sour water stripper (SWS) acid gas to amine acid gas ratio than has been typical for existing ...
