Abstract
A method as provided wherein betaine is separated eluted from beet molasses using a chromatographic simulated moving bed system having at least three chromatographic columns connected in series. The betaine is eluted during the same cycle as sucrose and rest molasses feeding and substantially simultaneous water feeding step, at least one water feeding step, a circulation step, and elution of sucrose, betaine and rest molasses fractions from selected columns.
Claims25
A method for the recovery of betaine and sucrose from beet molasses as substantially separate product fractions during the same cycle of a chromatographic simulated moving bed system having at least three chromatographic columns connected in series and adapted for the flow of liquids in a single direction through the columns, said cycle comprising
- a molasses feeding step comprising feeding a molasses feed solution into one of said columns and substantially simultaneously feeding eluent water into another of said columns, followed by the two following steps either one or several times;
- an eluent water feeding step comprising feeding water into one of said columns, and
- a circulation step comprising circulating said molasses feed solution and said water through said columns,
- wherein product fractions are eluated during said molasses feeding step, said eluent water feeding step, or both said product fractions selected from the group consisting of a rest molasses fraction, a betaine fraction, and a sucrose fraction, wherein each of said product fractions are recoverable during said cycle.
A method for the recovery of betaine and sucrose from beet molasses as substantially separate product fractions from a chromatographic simulated moving bed system having at least three chromatographic columns connected in series and adapted for the flow of liquids in a single direction through the columns, sequentially comprising
- (1) feeding a molasses feed solution into the top of one of said columns and eluting a rest molasses fraction from the bottom of a column downstream from said column top which is fed with said molasses feed solution;
- (2) feeding water into one of said columns downstream from said column which is fed with said feed molasses solution at substantially the same time as said feeding of said molasses feed solution, and eluting product fractions comprising a sucrose fraction followed by a betaine fraction from a column downstream from said column which is fed with water;
- (3) circulating said molasses feed solution and the water in said direction of flow through said columns without feeding molasses feed solution or water into said column or removing any product fractions;
- (4) feeding water into one of said columns and eluting rest molasses from a column downstream from said column which is fed with water;
- (5) circulating said molasses feed solution and the water in said direction of flow through said columns;
- (6) feeding water into one of said columns and eluting reset molasses from a column downstream from said column which is fed with water;
- and
- (7) circulating said molasses feed solution and the water in said direction of flow through said columns.
