Abstract

The invention provides a regenerating device of a natural gas sulfur recovering and complexing ion catalyst. The device comprises a tank body, an electrode plate, a liquid inlet, a gas inlet and a liquid outlet, wherein the tank body is provided with a regeneration reaction cavity, the electrode plate comprises a cathode plate and an anode plate, the liquid inlet is formed in the tank body, communicated with the reaction cavity and located at the upstream portion of the electrode plate, the gas inlet is formed in the tank body, communicated with the reaction cavity and located on the side, away from the electrode plate, of the liquid inlet, the liquid outlet is formed in the tank body, communicated with the reaction cavity and located at the downstream portion of the electrode plate. The scale of the regenerating device of the natural gas sulfur recovering and complexing ion catalyst based on the electrochemical principle is effectively reduced; especially, the regenerating device of the tank body structure can be applied to a natural gas sulfur recovering device under the floating type conditions, the regeneration rate of the complexing ion catalyst can be effectively increased, the consumption of the catalyst is reduced, and the scale of the device is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of catalyst preparation, in particular to a complex iron catalyst regeneration device for natural gas sulfur recovery. Background technique [0002] The existence of sulfuric acid gas in natural gas will increase the corrosion of pipelines and equipment, thereby affecting the service life of pipelines, and sulfur-containing natural gas will have peculiar smell when burning, and the SO produced by burning 2 compounds can pollute the environment. Therefore, the most important task in natural gas pretreatment is desulfurization. [0003] Complex iron catalyst regeneration is an important part of natural gas purification production process, the purpose is to regenerate complex iron catalyst after desulfurization reaction, so as to realize the recycling of complex iron catalyst. At present, in the natural gas desulfurization and purification process, due to the low solubility of oxygen in the solution and the s...
