Abstract
The invention provides an industrially advantageous method of separating liquid mixtures which can reduce the liquid film temperature drop in module units. As a result, the separation system can be rendered compact, the treatment capacity can be increased and the cost can be reduced. Thus, the method of the invention is effective in curtailment of separation and purification processes in the chemical industry and in putting high-efficiency membrane separation techniques to practice use. Its industrial utility is very great.
