Method for separation and concentration of propane-1,3-diol, obtained through the glycerol fermentation and the system for separation and concentration of propane-1,3-diol, obtained through the glycerol fermentation

摘要

way of secretion and concentration of 1,3-propanediol, according to the invention, the emerging during the fermentation of glycerol using nanofiltracji, characterised by the fact that the solution after fermentation of glycerol are separated using a three-step process nanofiltracji, inverted osmo zy and membrane distillation, retaining micro-organismsmost of the salt and colloidal compounds and carboxylic acids in the process of nanofiltracji.in the process of nanofiltracji apply membrane przepuszczaju0105ce 1,3-propanediol and formed in the shape of a tube, and the permeate is allocated in the reverse osmosis membrane using for which the coefficient of 1,3 propylene glycol is less than 50%, and the coefficient to stop anya other constituents of the solution above 50%.the permeate is concentrated in membrane distillation process, with which the distillate obtained back into solution supply process nanofiltracji, adding it in such quantities that increase in volume nadawy never exceeded 35%.system for the secretion and concentration of 1,3-propanediol during fermentation of glycerol using nanofiltracji, is characterised by having an nanofiltracji (1) equipped with membranes formed in the shape of a tube, which is connected with the outlet of the filtrate reverse osmosis pump installation (2).through permeatu reverse osmosis installation (2) is connected with the inlet of the distillation membrane (3). reverse osmosis installation (2) is equipped with diaphragms, which are below 50% 1,3 propylene glycol, and above 50% of the remaining components of the solution.nanofiltracji installations (1) and reverse osmosis (2) are equipped with tanks concentrated, (4, 5) and the membrane distillation (3) is equipped in the tank (6) connected in addition to distillate loop nadawy nanofiltracji installation (1).
