<p>Separate stripping (14) and rectifying (16) sections are arranged in tandem, each section being segregated into a plurality of vapor liquid contact stages (24-32, 34-42). The rectifying section (16) is operated at a higher temperature than the stripping section (14) by compressing (66) vapor from the stripping section (14) prior to introducing the vapor into the rectifying section (16). Thermal energy is conserved during the distillation process by transferring thermal energy from the rectifying section (16) to the stripping section (14) with a plurality of heat pipes (84-87). </p> |
