FIELD: technological processes.
SUBSTANCE: present invention relates to sulphur compounds in hydrocarbon flow extracting method. Method involves supply of hydrocarbon flow containing sulphur compounds, into preliminary washing zone, containing ammonia, extraction of hydrocarbon flow subjected to preliminary washing from preliminary washing zone and supply of hydrocarbon flow subjected to preliminary washing into mass transfer zone for extraction of one or more thiol compounds from hydrocarbon flow subjected to preliminary washing. Said mass transfer zone includes hollow-fiber membrane contactor, and thiol compounds removal takes place through pores in pipes wall.
EFFECT: said method enables to minimize number of equipment required for thiol compounds removal, and wherein liquefied petroleum gas or light naphtha have required characteristics.
