Abstract: A cost effective and environmentally acceptable method for removal of hydrogen sulfide from sour gas streams associated with source materials such as geothermal and petrochemical energy sources. The method comprises the steps of scrubbing inert, non-combustible components such as carbon dioxide from the sour gas, flowing the remaining combustible gas for further processing including compression, cryogenic liquifaction, and expansion to segregate hydrogen sulfide and gaseous components having a similar critical temperature from "clean" combustible gaseous components. The hydrogen sulfide and gaseous components of similar critical temperatures are then disposed of by ignition in a heat exchanger and fluidized bed scrub, converting hydrogen sulfide to sulfur dioxide which is scrubbed from the exhaust before release to the atmosphere. The clean combustible gaseous components are combusted and utilized to drive generators thereby providing a net energy output for the inventive abatement scheme.
