FIELD: oil and gas industry.
SUBSTANCE: described plant of hydrogen sulphide and light mercaptans blowing from the oil, including the desorber, equipped with the lines of heated oil inlet and cleaned oil discharge, the circulating gas flow supply line, and the vent gas discharge line. At the vent gas discharge line there is the low-temperature chelate purification unit by absobent, based on the chelated iron complexes, equipped with the cleaned gas discharge lines as the circulating gas flow, the air inlet, and the vent gas discharge and the sulfur suspension supply into the heated oil inlet line.
EFFECT: reduction of energy costs and increase of industrial safety.
