Claim Text:
1. A short-flow system for desulfurization of circulating hydrogen, comprising: a heating burner that is configured for heating a raw oil; a hydrogenation reactor that is connected to the heating burner; a heat exchanger that is connected to the hydrogenation reactor; an air cooler that is connected to the heat changer; a high-pressure separator device that is directly connected to the air cooler and is configured to separate a circulating hydrogen mixture containing hydrogen sulfide and heavy hydrocarbons from a formed oil; a de-hydrocarbon device that is directly connected to an outlet of the high-pressure separator device and configured to remove condensed heavy hydrocarbons from the circulating hydrogen mixture received from the high-pressure separator device by separating liquid drops of the condensed heavy hydrocarbons in a dispersion phase from the circulating hydrogen in a continuous phase, and obtaining a condensed heavy hydrocarbon phase and a mixture phase of circulating hydrogen containing sulfur, the air cooler is upstream of the high-pressure separator and the de-hydrocarbon device is provided downstream of the high-pressure separator; a desulfurizer device that is connected to a gas phase outlet of the de-hydrocarbon device, the desulfurizer device being configured to separate the obtained mixture phase to remove sulfides therein, so that circulating hydrogen without sulfur is obtained; a de-amine unit that is disposed within the desulfurizer device, the de-amine unit being configured to separate the obtained circulating hydrogen without sulfur to remove the amine solution therein, so that purified circulating hydrogen is obtained; and a vortex separator unit that is disposed within a top part of the desulfurizer, wherein the high-pressure separator device is separate from the de-hydrocarbon device.
