| titleOfInvention | The method of the compound rectifying separation recovery of saltouing of ethanol, acetone and propyl carbinol and device |
| abstract | The method that the compound rectifying separation of saltouing that the invention discloses ethanol, acetone and propyl carbinol reclaims and device; Biological propyl carbinol fermented liquid is entered wine with dregs tower and carries out preliminary concentrate by the method, and discharge useless mash at the bottom of tower, tower top obtains thick alcohol; Thick alcohol directly and salts solution carry out adverse current salting-out extraction at tower of saltouing, the volume ratio of salts solution and thick alcohol is (0.1 ~ 5): 1, extraction temperature is 60 ~ 90 DEG C, tower top feed liquid is made up of gas phase discharging and liquid phase discharging, gas phase discharging directly enters acetone tower, and liquid phase discharging directly enters propyl carbinol; Raffinate at the bottom of tower of saltouing re-uses after pervaporation; Be separated successively through propyl carbinol tower, acetone tower, ethanol tower, the content of the propyl carbinol obtained, acetone and ethanol is not less than 99.8%, 99%, 95.1% respectively.Present method makes the process for separating and purifying of propyl carbinol more simple, improves the separation recovery efficiencies of total solvent, reduces energy consumption. |
