ENV-98-174 Case Studies And Design Considerations Of LO-CAT II H2S Oxidation Units In Refinery And Oil & Gas Applications

Description:

Hydrogen Sulfide is a toxic and corrosive gas that is often present at significant levels in many refinery applications. Hydrogen sulfide can be produced naturally during the formation of natural gas and oil from the decomposition of plant life; or synthetically in hydrogenation and hydrodesulfurization processes. The LO-CAT II technology is an iron-based liquid redox process which selectively removes HIS from gas streams and converts it into elemental sulfur. Several design options are available to treat sour gas streams at low and high pressures. This paper discusses the design considerations for several recent LO-CAT II units used to remove H2S from refinery and oil/gas applications.
