Method for obtaining and dehydration of acetone, butanol and ethanol from their water solution, preferably from fermentation broth, through membrane distillation

摘要

method for obtaining and drainage of acetone, butanol and ethanol is suchthe mixture water abe or brzeczku0119 pofermentacyjnu0105 undergo membrane distillation module with membranami hydrofobowymi markers.with over permeatu is conducted on the surface of cooling, followed by wykroplenie permeatu to paddle and condensate tank permeatu,containing approximately 2-fold higher concentration of organic constituents (abe), and the resulting distillation membrane permeate heading into the tankwith the mixture of abe heading for distillation to obtain a mixture or a mixture zatu0119u017conej abe heading for modules to perwaporacji vacuum or termoperwaporacji,the permeate after process perwaporacji or termoperwaporacji is a mixture of acetone, butanol and ethanol (abe) and water is directed to the tank (the phase),in the chapter on the upper organic phase containing from 60% to 70% abe and from 30% to 40% water, and the aqueous phase containing the ok. 80% water and 20% abe.
