Abstract
The standard for sulfur content in natural gas in the globe is summarized.On this basis,the latest research and application progress about desulfurizing agents,such as complexed iron,amines,ionic liquids,and biomass,for wet removal of hydrogen sulfide are reviewed.In addition,the working principles of various desulfurizing agents are summarized in detail.Finally,the problems existing in the application of different desulfurizing agents in the wet removal process of hydrogen sulfide and research direction in the future are analyzed and prospected,aiming to provide theoretical and practical guidance for promoting the research and development of desulfurizing agents for removing hydrogen sulfide from natural gas.
