ABSTRACT:
An apparatus for generating at least two vapor zones, one above the other, by vaporizing a fluid mixture having at least two compounds therein having different vaporizing temperatures. The apparatus includes a chamber with vaporizing means, and vapor condensing means. Condensate recovery means is provided for recovering the condensed vapor and the condensate recovery means is in flow communication with a separation device for receiving the condensate from the condensate recovery means. The flow communication between the condensate recovery means and the separation device is external of the chamber. The separation means revaporizes the liquid with the lower vaporizing temperature for return to the vapor zone in the upper portion of the chamber and separates as a liquid the fluid having a higher vaporizing temperature.
