Application Note: pH Measurement In Tail Gas Clean-Up

Crude oil contains varying amounts of sulfur that must be managed in a refinery to produce products with acceptable environmental impact. During crude processing, the sulfur becomes hydrogen sulfide and organic sulfides, producing sour gas. These compounds are removed and recovered using first a Claus sulfur recovery unit (SRU) and later a tail gas cleanup unit (TGCU). Refineries can typically reclaim 99.9% of the sulfur present in the original crude.
