Article Summary. 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 ammonia (NH3)-burning SRUs.
