摘要：A process for obtaining one or more than one salt of an organic acid(s), or organic acid(s), from an aqueous sugar stream comprising one or more than one mineral acid and the organic acid(s) is provided. The process comprises introducing the aqueous sugar stream to a separation system comprising one or more beds of anion exchange resin and obtaining a stream therefrom comprising the sugar. The one or more beds of anion exchange resin are then regenerated in one or more stages to produce at least one product stream comprising the organic acid, a salt of the organic acid, or a combination thereof, and a separate outlet stream comprising the mineral acid, a salt of the mineral acid, or a combination thereof. The product stream is then recovered. The separation may be conducted with two separation units, or using a single anion exchange unit.
