从120号溶剂油中提取正庚烷并回收甲基环己烷的可行性研究

Research on the Feasibility to Refine n-heptane and Reclaim Methylcyclohexane from 120 Solvent Oil

从溶剂油中提取具有广泛用途的正庚烷,是现阶段经济有效的方法.根据该生产过程的特点,我们提出我国中小型石化企业生产正庚烷的可行性.研究比较各种分离方法,提出了用复合萃取分离法从120号溶剂油中分离出正庚烷并回收甲基环己烷的方案.

Refining n-heptane from solvent oil is an efficient and economic method and the refined n-heptane is now widely used in chemical industry. Based on the characteristics of the refining process, the feasibility for small and medium-sized plants to produce n-heptane was identified. Having compared all separating ways, the authors made a proposal to refine n-heptane and reclaim methylcyclohexane from 120 solvent oil by using composite extraction separation.
