Geothermal Steam Economic H2S Abatement and Sulfur Recovery

Abstract

A serious problem that occurs in geothermal steam power projects is the emission of hydrogen sulfide. This problem is not easily rectifiable and as a result, the geothermal steam industry has a need for H2S abatement technology that is suitable and economic for use in geothermal steam facilities. Current technology has proven to have high capital and/or operating costs and some processes are difficult to operate.
In answer to the requirement for new technology and for companies to be environmentally responsible, Xergy Processing Inc. has developed a gas phase direct oxidation process for treating H2S in the range of 0.1 to 20 t/d which has several applications. The process is ideally suited for H2S abatement in geothermal power processes. The process has low capital and operating costs, and is easy to operate utilizing equipment that is familiar to industry.
