FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil and gas industry, particularly to plants for collection and cleaning hydrogen sulphide-containing gas at oil fields, and can be used for neutralisation of hydrogen sulphide in emissions of reservoir gas in conditions of oscillating mode of filling water-oil emulsion. Sulphur trap includes vertical cylindrical housing having inside a vertical pipe, raw material supply nozzle, gas discharge nozzle, sulphur discharge nozzle. In housing coaxially to vertical pipe there is a barrel with bottom upwards from bottom of housing to height which does not reach top of housing, connection of vertical pipe and barrel bottom is air-tight, vertical pipe and barrel are installed eccentrically in housing, sulphur trap is equipped with horizontal separator with inclined bottom and cover connected to inner volume of barrel by a pipe, around horizontal separator there is a jacket connected by a channel with inner volume of housing with pipe inside channel, raw material supply nozzle is connected to vertical pipe above barrel, gas discharge nozzle is connected to vertical pipe above raw material supply nozzle, sulphur discharge nozzle is connected to inner volume of horizontal separator near lower part of inclined bottom, sulphur trap is additionally equipped with a first heat carrier feed nozzle arranged to feed heat carrier into lower part of housing, a second heat carrier feed nozzle arranged in lower part of jacket, a first heat carrier discharge nozzle arranged in upper part of housing, a second heat carrier discharge nozzle arranged in upper part of jacket, a second gas discharge nozzle in cover of horizontal separator, wherein cross-sectional area of vertical pipe and cross-sectional area of horizontal separator are in ratio of 1:(16-18).
EFFECT: invention ensures reduction of gas loss with sulphur.
