ABSTRACT:
A method for distillation of a multiple-component liquid/solid system, for example, used engine coolant at two different vaporizing pressures. One component, for example, water, is separated into one distillate stream at a first pressure and the other component, for example, ethylene glycol, is separated into another distillate stream at a second pressure. Each distillate stream is directed toward an individual storage tank.
