【摘要】 总结了现有几种盐效应气液平衡(VLE)、液液平衡(LLE)模型,对它们的优缺点进行了比较。综述了溶盐精馏、加盐萃取精馏、加盐萃取-恒沸精馏联合过程、精馏-盐效萃取耦合过程的基本原理、操作特性及适用物系,对选择应用盐效分离方法分离具体物系起到指导作用。更多还原

【Abstract】 Several kinds of models of VLE, LLE of salt-contained solution are summed up and comparing with each other,which is the basis of designing the salt separation process.The advantages and disadvantages of salt distillation, salt-added extraction distillation, salt extraction-azeotrope distillation combined process and distillation-salt extraction process are discussed indetail, which is useful in guiding people to select the fittest method for aspecial system.更多还原
