METHOD OF TREATMENT AND DEHYDRATION OF NATURAL AND ASSOCIATED PETROLEUM GAS WITH HIGH CONTENT OF HYDROGEN SULFIDE Russian patent published in 2001 - IPC

FIELD: gas and oil producing industry, particularly, methods of gas desulfurization. SUBSTANCE: treatment and dehydration of natural and associated of sulfur dioxide by combustion of sulfur and sulfur-containing compounds in furnace, its mixing with solvent, washing with said solution of initial gas to remove hydrogen sulfide with obtaining of elementary sulfur and water, withdrawal of sulfur suspension and separation of sulfur from solvent, return of solvent and a part of sulfur to process of treatment and also gas dehydration by water absorption from gas in two stages. First, initial gas is washed with aqueous solution of sulfurous and sulfuric acids and sulfur dioxide produced by treatment of flue gases formed in combustion of regeneration gases and partially sulfur in boiler furnace, and final treatment and dehydration of gas on solid adsorbers with utilization of heat from combustion of regeneration gases and sulfur. EFFECT: increased degree of desulfurization and dehydration of gases at simplification of process. 1 dwg
