摘要： A process for the reclamation of spent aqueous alkanolamine solutions by contacting a spent aqueous alkanolamine solution with a strong base ion exchange resin for time sufficient to sorb from the aqueous alkanolamine solution at least a portion of the accumulated ions and after a high concentration of ions accumulate on the resin, regenerating the strong base ion exchange resin by: a) purging the resin with water or nitrogen, b) contacting the strong base ion exchange resin with a sodium chloride solution for a time sufficient to remove the ions, c) purging the resin to remove the sodium chloride solution, d) contacting the resin with an alkali metal hydroxide solution, preferably sodium hydroxide, for a time sufficient to convert the resin to a substantially hydroxide form; and e) purging the resin, wherein the ion sorption capacity of the resin is maintained at a substantially constant value.
