ABSTRACT:
A process for vaporizing a working liquid and condensing the vapors thereof is provided wherein the heat of compression is used in vaporizing the liquid. In the process, the working liquid is compressed to a high pressure thereby adding heat of compression thereto. This heat of compression is transferred from the working liquid to a still as a result of which the liquid is vaporized and contains sensible heat. The fluid containing this sensible heat is passed to an evaporator and substantially all sensible heat over that used to boil-up said liquid is removed by heat transfer contact between the fluid containing the sensible heat through use of an auxiliary condensing coil, so that thermal balance is maintained.
