Natural gas produced from overseas large natural gas fields are basically condensate gas containing a mass of organic sulfur. Up to now, there is no mature technology available for deep organic sulfur removal in China. Analyzed and compared are adaptability and advantages and disadvantages of domestic and overseas different organic sulfur removal technologies, combined with typical organic sulfur removal processes, reintegrated are the available organic sulfur removal techniques and proposed is the compound, synchronous and deep organic sulfur removal technology by dry method and wet method. The technology is compared with foreign advanced proprietary technology in such aspects as process flow, construction investment and operation difficulty and put forward is a complete set of natural gas organic sulfur removal technology.
