Integration and Testing of a Cogenerating Concentrating Solar Collector with Advanced Alcohol-Distillation Equipment.

摘要

An advanced concept of vapor recompression of alcohol in a distillation column has been demonstrated. Its potential as a primary method separating alcohol from water lies in its operational simplicity, potential for automation, and low operating cost. Though it does use electrical power to drive the compressor, the benefits of using the heat of condensation to drive the reboiler warrant its use. Further development of a small alcohol burner to initiate startup and provide some reflux heat would eliminate any boiler with required water treatment, feed system, blodwdown, and other operation/maintenance aspects. Full heat recovery on the beer feed/stillage/alcohol subsystems and the reflux/ vapor compression intake greatly enhance performance. (ERA citation 08:035382)
