摘要
在我国加快海外天然气勘探开发的过程中,国外大型气田均为含硫凝析油气田,且含有大量有机硫,国内尚无较成熟的深脱有机硫技术。通过对国内外不同脱有机硫工艺技术的适应性及优缺点进行研究比较,结合典型的脱有机硫工程,重新整合现有脱有机硫工艺,提出干法和湿法复合深度同步脱有机硫技术,从工艺流程、工程投资、操作难度等方面与国外先进专利技术进行比较,提出一套完整的天然气脱硫脱有机硫工艺技术。
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.
