由于能源危机,近来曾发表了许多关于蒸馏中节能方面的文章.因此,人们也许认为没有开发的余地了,但事实远非如此.工业生产中的分离过程很多用到蒸馏操作,它在化学工业的投资和操作费用中占有相当大的比例.因此,人们希望蒸馏操作成为进一步研究和改进的主要目标.然而,正如Fair所指出的,蒸馏操作往往没有竞争性的比较方案,而经常是 As a result of the energy crisis, there have been many articles published recently on energy efficiency in distillation, so one may think there is no room for development, but far from the fact that the separation process in industrial production is often used in distillation operations, Of the investment and operating costs account for a significant proportion Therefore, it is hoped that the distillation operation will be the main target for further research and improvement However, as pointed out by Fair, distillation operations often do not have competitive alternatives and are often
