| Hydrogen sulfide (H2S) is a poisonous gas, mainly arises in various industrial processes, and also exists in the natural plant and animal body in the ecological environment of the natural system of corruption process. Its existence is not only influence the health, but also do metal pipes and equipment serious corrosion in hot and humid conditions. Corrosion cracking brought on the H2S gas pipeline network damaged when the accident occurred. Therefore, China and some foreign countries permitted concentration of hydrogen sulfide strictly limited under different circumstances, and required the use of natural gas must be desulphurized first. If H2S was direct emitted or combust transforming into sulfur dioxide, the atmosphere would be caused serious environmental pollution. Therefore, H2S must be desulphurized for the environment or the production. This paper studies on hydrogen sulphide removal of natural gas in a rotating packed bed (RPB) by oxidation reduction method. Try to experiment ferric chelated 888 and ADA three different desulfurizer in the rotating packed bed, and select the most suitable desulfurizer for the rotating packed bed. The main contents and findings are summarized as follows.1. In a rotating packed bed (RPB), in order to determine the operating conditions of the system, the effect of the inlet concentration of H2S, gas flow rate, liquid flow rate, rotor speed, pH value of desulphurization liquid on the coefficient of mass transfer and the removal rate of ferric chelated, 888 and ADA three different desulfurizer systems were studied, and the optimum condition was obtained: gas flow rate is 4m3·h-1 , liquid flow rate is 1000 L·h-1, rotor speed is 1200r·min-1, then H2S can be removed to 20mg/m3 to conform to the state requirements and H2S removal rate can reach about 99.9%.2. In ferric chelated, 888 and ADA three different desulfurizer systems, the rotor speed enhance ferric chelated desulfurizer system the most mass transfer. In ferric chelated desulfurizer systems, alkali consumption at least, the most economic, the removal rate of H2S could reach around 99.9%. It has a very good industrial application prospect.
