摘要
真空膜蒸馏 (VMD)过程是一种新型的膜分离技术 ,本文分析了影响VMD过程的主要因素 (真空度、进料温度、进料流速和浓度等 ) ,对目前VMD过程实验研究 (易挥发物系和难挥发物系 )、过程模拟研究及应用研究现状和进展等方面进行评述 ,提出了VMD过程目前存在的问题 。
VMD is a new kind of membrane separation technique. In this paper,the main factors which affect VMD process (including vacuum degree,temperature and concentration of feed,velocity of feed flow),the headway of current experiment research and the application research are discussed.The existing problems in current research are pointed out,and the research direction of VMD is also indicated.
