FIELD: oil and gas industry.
SUBSTANCE: invention is related to petrochemical and gas industries and may be used during wells development at deposits of natural hydrocarbon gases. Hydrogen sulfide and mercaptans are oxidised (P-1) in presence of catalyst with production of elemental sulfur and sulfur dioxide. The received gas is cooled till elemental sulfur is condensed and delivered to tandem layer of adsorbent (A-1), (A-2). At input temperature of the adsorbent is maintained at temperature of 130-150°C and at the output - 100-120°C.
EFFECT: invention allows continuous treatment of gas flows from hydrogen sulfide with variable flow rate and composition.
