APPARATUS AND METHOD FOR SULPHIDE RECOVERY FROM HYDROCARBON FLUX Russian patent published in 2009 - IPC C10G19/02 

FIELD: chemistry.

SUBSTANCE: there are described apparatus and method for sulphide recovery from hydrocarbon flux. The prewashing module designed to convert hydrogen sulphide to hydrosulphuric acid salt resulted from the alkali reaction including caustic soda, is connected to the recovery module directly superadjacent with respect to the prewashing module, designed to convert mercaptans to mercaptides resulted from the alkali reaction. The hydrocarbon product is delivered from the recovery module through the coalescing component that prevents alkali withdrawal with the hydrocarbon product flux. The prewashing module designed to convert hydrogen sulphide to sodium sulphide resulted from the alkali reaction including caustic soda, ensures the hydrocarbon flux prepared to recovery. In the prewashing module, alkali liquor is sampled continuously, with recovered alkali continuously added.

EFFECT: reduced investments required to manufacture the recovery system.
