摘要
The removal of hydrogen sulfide from gas plays an important role in rational utilization of resources and environ-mental protection.In this paper,the process of hydrogen sulfide removal by wet oxidation method in a rotating packed bed was investigated in a scale for treating 10000 Nm3/h of gas.On the basis of studying the influence of the species and con-centration of alkali source,the liquid/gas volume ratio,the high gravity factor,and the hydrogen sulfide content in feed gas on the desulfurization effect,the suitable technological conditions were obtained.The hydrogen sulfide removal efficiency could reach 98.0%under these conditions.The results of continuous operation of process facilities showed that the high gravity method has many merits including higher desulfurization rate,good stability in operation,lower liquid/gas volume ratio,greater operation elasticity,and apparent energy saving effects.
