Abstract
Methods of regenerating a strong base anion resin are described. The method comprises collecting a salt-containing product from a chromatographic system configured to process a biomass derived material. The salt-containing product is processed through a nanofiltration membrane to collect a salt-containing permeate, which is used to regenerate a spent strong base anion resin. The biomass may be a plant-based material, such as sugar beets or sugar cane. A system for regenerating a strong base anion resin is also described.

A method of regenerating a strong base anion resin comprising:
- collecting a salt-containing product from a chromatographic system, the chromatographic system configured to process a biomass derived material;
- processing the salt-containing product through a nanofiltration membrane to collect a salt-containing permeate;
- and
- utilizing the salt-containing permeate to regenerate a strong base anion resin.
A method for regenerating a strong base anion resin, the method comprising:
- collecting a salt-containing product from a chromatographic system, the chromatographic system configured to process a sugar beet derived material;
- processing the salt-containing product through a nanofiltration membrane to collect a salt-containing permeate;
- and
- utilizing the salt-containing permeate to regenerate a strong base anion resin.
A method of regenerating a strong base anion resin, the method comprising:
- processing a biomass feed stream through a chromatographic system to produce an extract fraction and a raffinate fraction;
- flowing a portion of the raffinate fraction through a nanofiltration membrane to produce a membrane permeate and a membrane retentate;
- and
- flowing the membrane permeate into a decolorization system containing a spent strong base anion resin to regenerate the strong base anion resin.
A system, comprising:
- a chromatographic system configured to separate a biomass feed stream into an extract fraction and a raffinate fraction;
- a nanofiltration system configured to filter the raffinate fraction and produce a membrane permeate and a membrane retentate;
- and
- a decolorization system configured to decolorize the extract fraction and to regenerate a spent strong base anion resin using the membrane permeate.
