Abstract
The present invention provides a novel apparatus and process for vaporizing a liquid and condensing the vapors thereof. The apparatus and process utilize heat of compression for vaporizing the liquid. The apparatus includes a still (10), a closed refrigeration system (12), an auxiliary condensing coil (24) separate from refrigeration system (12), and a valve (28) for controlling heat extraction by auxiliary coil (24). In a particularly useful embodiment, the apparatus further includes a trough (41) for collecting the condensed vapors. The trough is located within still (10). Auxiliary coil (24) extracts from the vapors, heat in excess of that necessary to maintain thermal balance in the apparatus. The novel process of the present invention includes the steps of compressing a gaseous working fluid to a high pressure and adding heat of compression thereto; transferring heat including the heat of compression from the working fluid to a liquid in still (10), as a result of which the liquid is vaporized and the resulting working fluid contains sensible heat; passing the resulting working fluid to evaporator coil (18) whereby the working fluid entering evaporator coil (18) contains the sensible heat; and removing from the vapors resulting from vaporization of the liquid, heat in excess of that necessary to maintain thermal balance in the apparatus (12). The excess heat is removed by auxiliary condensing coil (24), which is separate from the refrigeration system.
