Method for separation of propane-1,3-diol solution obtained through the glycerol fermentation

摘要

the distribution of 1,3-propanediol fermentation glycerol obtained by using nanofiltracji, characterised by the fact that the solution after fermentation of glycerol are separated dwustopniowo using process nanofiltracji and reverse osmosis.process nanofiltracji powering method wsadowu0105, whole volume of solution, and the obtained permeate nf are separated in the process of reverse osmosis, in which a portion of permeatu nf is concentrated to obtain the coefficient of 1,3 propylene glycol at a level lower than 50%. subsequently, resulting in reverse osmosis installation further cavity volume nadawy complements obtained permeatem nf.
