【摘要】 本文运用残余曲线图对八碳烯分离过程进行了分析研究,提出了采用非均相共沸精馏的方法脱除待分离物系中的水的新工艺。研究结果表明,该方法即节省了原工艺中脱水所需的一些设备,又降低了分离能耗,并且可大幅度提高脱水效率,改善产品质量。更多还原

【Abstract】 2,5-dimethyl-2,4-hexadiene separation process is studied with residue curve maps in this paper.The new dehydration process of 2,5dimethyl-2,4-hexadiene separation with heterogeneous azeotropic distillation is proposed.The results illustrate the new process would not only reduce some investment in equipment needed by the dehydration in old process,but also save separation energy consumption,and improve the dehydration efficiency and product quality.更多还原
