| description | A method and an apparatus to condense and rectify alcohol, and more particularly to a method and an apparatus suitable for the energy-saving condensation and rectification of high-purity alcohol from the synthesized alcohol, the used alcohol aqueous solution in food industry and the fermented alcohol. The method makes it possible to extract and recover alcohol of 99 wt % or higher with small quantity of propane solvent, using the propane in supercritical or pseudocritical conditions in the process of condensation and recovery of alcohol from aqueous solution of alcohol. Further, the method makes it possible to condense alcohol to the concentration of 95 wt % or higher by increasing the selectivity of alcohol through the cooling of the propane to liquid state. |
