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.

A batch process for separating a multiple-component solution comprising used engine coolant consisting of a mixture of water, glycols and substantially nonvolatile components so that the used engine coolant may be recycled, the process comprising the steps for: a) placing the mixture in a single heated vessel, b) heating the mixture to a first temperature at a first pressure equal to or greater than atmospheric pressure to vaporize the water, condensing and directing the water to a container, c) sensing a physical condition indicative of the fact the water has substantially entirely vaporized, d) in response to said sensed condition automatically heating the mixture to a second temperature and at a second pressure less than atmospheric pressure to vaporize the glycols, said second temperature and second pressure selected to prevent the formation of acids and the discoloration of the glycol, condensing and directing the condensed glycols to a container, e) automatically discontinuing heating while the residue in the vessel is still flowable, and f) draining the flowable residue from the vessel. A batch process for separating a multiple-component solution comprising used engine coolant consisting of a mixture of water, glycols and substantially nonvolatile components so that the used engine coolant may be recycled, the process comprising the steps for: a) placing the mixture in a single heated vessel, b) heating the mixture to a first temperature between 200°-220°F. at a first pressure equal to or greater than atmospheric pressure to vaporize the water, condensing and directing the condensed water to a first container, c) sensing a physical condition indicative of the fact the water has substantially entirely vaporized, d) in response to said sensed condition automatically heating the mixture to a second temperature less than 280°F. at a second pressure less than atmospheric pressure to vaporize the glycols, condensing and directing the glycols to a second container, e) automatically discontinuing heating while the residue in the vessel is still flowable, and f) draining the flowable residue from the vessel.
