NMP萃取精馏分离芳烃和非芳烃
Separation on the Aromatics and Paraffin by Extractive Distillation with NMP
摘要
Abstract
Through the experiments of VLE and extractive distillation, itshowed that the solvent NMP was a good separating agent and satisfied the requirement of current ecologically chemical engineering. Using NMP as extractant and utilizing the property of the water added will lower the boiling point of NMP-water mixture, a modified process different from the the ordinary two towers process was proposed. The calculation showed that it raised the yield ratio of benzene from 94.2% to 98.2%. Since the modification of the ordinary process was not so complex,the proposed modified process had certain industrial significance.关键词
