Liquid redox sulfur recovery options, costs, and environmental considerations for the natural gas industry

Conference ·
OSTI ID:5533782
Liquid redox chemistry has been employed for sulfur removal and recovery applications since the 1950's. The first process to be used commercially was the Stretford process, which was used extensively in the United States in the 1960's as a replacement for the iron sponge process in the treatment of sour town gas. In recent years, the Stretford process has been joined in the United State' marketplace by several other liquid redox processes including the Unisulf, Sulfolin, LO-CAT, SulFerox, and Hiperion processes. This paper describes the chemistry and engineering options available with each process, as well as the environmental and cost considerations associated with these processes.
