- 摘要:
- 天然气脱硫脱碳技术在天然气净化工艺中占有举足轻重的地位。常用的脱硫脱碳方法主要包含物理溶剂法、化学溶剂法、化学物理溶剂法、膜分离法等。其中胺法脱硫尤其是基于醇胺的化学溶剂法及物理化学溶剂法是目前天然气处理、深度预处理中广泛使用的方法。论述了基于醇胺溶液的化学法及化学物理溶剂法在脱硫脱碳领域的发展状况，重点介绍了复合醇胺法中基于醇胺尤其是 MDEA 的配方溶液的大致组成、使用范围及优缺点。基于醇胺尤其是 MDEA 的配方溶液可针对不同的工况并与适当的工艺流程相匹配，最大限度地提高硫脱除率，不但用于脱除原料天然气中的含硫组分，而且广泛应用于硫黄回收单元之前的酸气提浓及后续的尾气处理。因此，基于醇胺尤其是 MDEA 的配方溶剂技术仍然是目前脱硫脱碳方法的主导技术。
Desulfurization and decarbonization is a decisive step in natural gas purification. A number of methods are available for removing acid gases from feed gas streams. Some of commonly used methods are physical solvent method, chemical solvent method, combination of the two methods, separation membrane,etc. Among these methods, amine method, especially the chemical solvent method based on alkylol amine and combination of physical solvent method and chemical solvent method, are used widely in natural gas treatment and deep pretreatment at present. Reviewed is the development status of the chemical solvent method based on alkylol amine and combination of physical solvent method and chemical solvent method in gas desulfurization and decarbonization, introduced are application scope and advantages and disadvantages of typical desulfurization and decarbonization methods and predicted is the future development tendency in gas desulfurization and decarbonization technology.
