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.

Abstract: An oxygenated hydrocarbon production system for producing an oxygenated hydrocarbon selected from tetrahydrofuran, 1,4-butanediol, and gamma butyrolactone using maleic anhydride. The oxygenated hydrocarbon production system first converts maleic anhydride to a monoester, then converts the monoester to a diester, passes the diester through an anion exchange resin to remove acid-containing species such as the monoester, then hydrogenates the diester to the oxygenated hydrocarbon. The anion exchange resin may be regenerated using a regeneration subsystem which contains a regeneration solution containing a strong base. The system is used in a method of producing an oxygenated hydrocarbon from maleic anhydride.

The system also includes at least one second anion exchange resin vessel configured to receive the flow of water having a majority of the long-chain PFAS compounds removed. The at least one second anion exchange resin vessel includes a second regenerable anion exchange resin therein having a high affinity for short-chain PFAS compounds and is configured such that a majority of the short-chain PFAS compounds sorb to the second anion exchange resin to remove a majority of the short-chain PFAS compounds from the contaminated water and produce a treated flow of water having a majority of the long and short-chain PFAS compounds removed.
