Abstract
Official abstract text for this publication.
Provided is a process for extracting valuable components from cane vinasse comprising a) filtering said cane vinasse to produce a retentate (RA) and a permeate (PA), b) concentrating said permeate (PA) to produce a permeate (PB) and a retentate (RB), c) performing ion exclusion chromatography on said retentate (RB) to produce an extract (EC) and a raffinate (RC), d) performing one or both of the following: i) performing affinity chromatography on said extract (EC) to produce a raffinate (RDI) that contains inositol and an extract (EDI) that contains glycerol, and ii) performing a separation on said raffinate (RC) to produce a retentate (RDII) that contains polycosanol.
First claim
Opening claim text (preview).
1 . A process for extracting valuable components from cane vinasse comprising a) filtering said cane vinasse to produce a retentate (RA) and a permeate (PA), b) concentrating said permeate (PA) to produce a permeate (PB) and a retentate (RB), c) performing ion exclusion chromatography on said retentate (RB) to produce an extract (EC) and a raffinate (RC), d) performing one or both of the following: i) performing affinity chromatography on said extract (EC) to produce a raffinate (RDI) that contains inositol and an extract (EDI) that contains glycerol, and ii) performing a separation on said raffinate (RC) to produce a retentate (RDII) that contains polycosanol. 2 . The process of claim 1 , wherein said filtering step a) is performed by microfiltration. 3 . The process of claim 1 , wherein said concentrating step b) is performed by reverse osmosis. 4 . The process of claim 1 , wherein said step c) of performing ion exclusion chromatography is performed using a strong acid cation exchange resin. 4 . The process of claim 1 , wherein said step d) i) of performing affinity chromatography is performed, and wherein said process of claim 1 further comprises the step of removing inositol from said raffinate (RDI). 5 . The process of claim 1 , wherein said step d) i) of performing affinity chromatography is performed, and wherein said process of claim 1 further comprises the step of removing glycerol from said extract (EDI). 6 . The process of claim 1 , wherein said step d) ii) of removing polycosanol from said raffinate (RC) is performed, and wherein said step d) ii) of removing polycosanol from said raffinate (RC) comprises A) performing nanofiltration or solvent extraction or winterization on said raffinate (RC) to produce a retentate (RDIIA), and B) removing polycosanol from said retentate (RDIIA).
