The invention relates to a short-flow process for desulfurization of circulating hydrogen and a device for the same. A short-flow process for desulfurization of circulating hydrogen is provided, comprising: (a) removing hydrocarbons from the circulating hydrogen mixture, so that the liquid drops of the heavy hydrocarbons in the dispersion phase are separated from the circulating hydrogen in the continuous phase, and a heavy hydrocarbon phase and a mixture phase of circulating hydrogen containing sulfur are obtained; (b) further separating the resultant mixture phase to remove the sulfides therein, so that circulating hydrogen without sulfur is obtained; (c) further separating the resultant circulating hydrogen without sulfur to remove the amine solution therein, so that purified circulating hydrogen is obtained. The invention also provides a device for desulfurization of circulating hydrogen.
