摘要/Abstract

摘要： C4 components are useful in industry and should be separated as individuals. A new process
wasproposed to separate them by extractive distillation, with the advantages of low
equipment investment, energyconsumption and liquid load in the columns. One principle to
improve the extractive distillation process was putforward. Moreover, the analysis of
operation state of the new process was done. There were eight operation statesfound for the
whole process, but only one operation state was desirable. This work provides a way to
effectivelyseparate C4 mixtures and helps the reasonable utilization of C4 resource.
