The application of GLT complex iron desulfurization prcocess in purification of sulphur-containing tail gas from hydrorefining
The GLT complex iron desulfurization process can purify various tail gases containing H2S generated by small and medium-sized hydrorefining units to ρ(H2S)<5 mg/m3,purified exhaust gas can be reused for resource utilization,and the removed sulphur is used to produce industrial sulphur.Compared with the traditional MDEA enrichment and sulphur recovery process,the GLT complex iron desulfurization process is simple,energy-saving and environmental protection,and there is no"three wastes"emission,which has good economic and environmental protection benefits.
