ABSTRACT:
This invention relates to a distillation device that employs a plurality of twin tubings of coaxial arrangement or of side-by-side arrangement wherein the vaporization takes place at an evacuated state in one tubing and the condensation takes place in the other tubing of the twin tubings. A blower or pump moves the vapor from the vaporization tubing to the condensation tubing and, consequently, creates an evacuated state in the vaporization tubing and a pressurized state in the condensation tubing. As the condensation takes place at a higher pressure in the condensation tubing compared with the vaporization in the vaporization tubing, the temperature of the condensation tubing is higher than the temperature of the vaporization tubing, and consequently, a very high percentage of the latent heat released by the condensing vapor is recycled from the condensation tubing to the vaporization tubing by conduction through the metallic wall dividing the condensation tubing from the vaporization tubing.
