Abstract
An evaporation apparatus including a vessel defining an opening at the top thereof and forming an evaporation chamber to hold a liquid composition; a condenser assembly disposed above and hermetically sealed to the vessel and having a wall defining a condensation chamber communicating with the evaporation chamber through the opening, an accumulator for receiving liquid condensed on the wall, and a drain for removing liquid received by the accumulator; a fluid drive disposed above the condenser assembly and adapted to produce fluid flow downwardly through the condensation chamber and into contact with the liquid composition in the evaporation chamber and then upwardly into the condensation chamber; a heating mechanism for heating the liquid composition in the evaporation chamber so as to cause evaporation thereof; and a cooling means for cooling the wall so as to produce condensation thereon of vapor included in the fluid flowing upwardly from the evaporation chamber.
