The invention provides a new type of sulfur reduction process equipment, and its technical proposal is mainly composed of a raw material impurity port (1), a liquefied gas filter (2), a liquefied gas outlet (3), a gas transmission pipeline (4), a circulation pipeline (5), Alkali liquid membrane contactor (6), fresh lye replenishment pump (7), replenishment pipeline (8), fresh lye storage tank (9), alkali wash pipeline (10), settling alkali wash tank (11), alkali Liquid heating heat exchanger (12), treated liquefied gas outlet (13), raw material liquefied gas inlet (14), lye filter A (15), lye filter B (16), alkali washing circulation pump (17) , alkali liquid sampling port (18), tee (19), filter pipeline (20), alkali washing liquid filter A (21), alkali washing liquid filter B (22), alkali washing operation pump (23), alkali The slag discharge outlet (24) and the heating pipeline (25) are composed; the present invention is well connected with the original technological process, occupies a small area, has obvious sulfur reduction effect, low production cost, and the newly added process is simple in design, low in cost, easy to operate, and has Extensive promotion and application value.

Description

technical field [0001] The invention relates to the technical field of liquefied gas desulfurization, in particular to novel sulfur reduction process equipment. Background technique [0002] At present, there are many desulfurization processes in China, but they have not been widely promoted because of high cost, difficult operation, and immature technology. For example, the domestic double-agent desulfurization process is complicated and the cost is high. In the production of the existing MTBE plant, the sulfur content of the product MTBE is too high, about 300ppm. At present, due to serious air pollution, the State Environmental Protection Administration has very strict requirements on vehicle exhaust emissions, especially the control of sulfur indicators. MTBE is the main blending agent of gasoline. To reduce the sulfur content in gasoline, the sulfur content in MTBE must be reduced. Therefore, MTBE sulfur reduction technology is imminent.
