摘要
介绍了目前国内几种主要的已经工业化的芳烃抽提工艺,并且从溶剂性质和产品质量等方面进行了比较。并且根据生产要求的不同,推荐了不同芳烃抽提的工艺。其中Sulfolane工艺为国内大多数装置所采用的工艺。
Current several industrialized aromatic extraction processes in China were introduced, and they were compared from the aspects of solvent nature and solvent quality. According to different production requirements, different aromatic extraction processes were recommended.
