摘要： A method for separation and concentration of a mixture, comprising the step of operating at least one or a part of distillation towers forming a distillation cascade by a dephlegmator for simultaneously performing a heat exchange and an evaporation to reduce the hold-up amount of liquid in an evaporation device so as to shorten a startup time, whereby a wasteful operating cost required for startup can be reduced, and a productivity can be increased remarkably.
