The apparatus and process utilizing heat of compression for vaporizing the liquid, 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 with still (10). Auxiliary coil (24) extracts from the vapors, heat in excess of that necessary to maintain thermal balance in the apparatus. |
