Reduced Energy Alcohol Separation Process Having Water Removal |
摘要 |
The present invention relates to the recovery of alcohols, in particular ethanol, from a crude ethanol product obtained from the hydrogenation of acetic acid using a reduced energy process. The crude ethanol product may be fed to a distillation column in which a substantial portion of the water is removed with the acetic acid in the residue. Additional water may be removed by using a pressure swing adsorption unit, molecular sieve, and/or membrane. Ethanol extraction may also be used to reduce the ethanol concentration in the recycle streams. |
