FIELD: chemistry.
SUBSTANCE: method involves: (a) removing hydrocarbons from a circulating hydrogen mixture such that liquid droplets of heavy hydrocarbons in the dispersed phase are separated from the circulating hydrogen in a continuous phase to obtain phases of heavy hydrocarbons and a mixed phase of circulating hydrogen containing sulphur; (b) further separation of the obtained mixed in order to remove sulphides to obtain circulating hydrogen which does not contain sulphur; and (c) further separation of the obtained circulating hydrogen which does not contain sulphur in order to remove an amine solution to obtain clean circulating hydrogen. The invention also discloses a device for desulphurating circulating hydrogen.
EFFECT: invention increases efficiency of treating circulating hydrogen mixture.
