Abstract: Processes and apparatuses for washing a spent ion exchange bed and for treating biomass-derived pyrolysis oil are provided herein. An exemplary process for washing a spent ion exchange bed employed in purification of biomass-derived pyrolysis oil includes the step of providing a ion-depleted pyrolysis oil stream having an original oxygen content. The ion-depleted pyrolysis oil stream is partially hydrotreated to reduce the oxygen content thereof, thereby producing a partially hydrotreated pyrolysis oil stream having a residual oxygen content that is less than the original oxygen content. At least a portion of the partially hydrotreated pyrolysis oil stream is passed through the spent ion exchange bed. Water is passed through the spent ion exchange bed after passing at least the portion of the partially hydrotreated pyrolysis oil stream therethrough.

Abstract: Water is demineralized by passage through a water demineralization system. The water demineralization system comprises a series of at least three ion exchange resin zones. The sequential series comprises a strong acid cation (SAC) resin zone, a first anion resin zone, and a weak acid cation (WAC) resin zone. The SAC resin zone comprises a SAC resin for removing cations from the water, the first anion resin zone comprises an anion resin for removing anions from the water, and the WAC resin zone comprises a WAC resin for removing cations from water without substantially splitting any salts present in the water. Means for connecting each resin zone in the series are provided so that water can pass sequentially through the system. A method is also provided for regenerating the WAC resin from sodium and ammonium exhaustants. This method comprises contacting the WAC resin with an aqueous solution of a regenerant that is substantially devoid of sulfur and halogen groups. The regenerant is selected from the group consisting of (a) organic acids, (b) inorganic acids, (c) amine salts of (a) and (b), (d) amines, and (e) combinations thereof.

Abstract: A process for treating wash water from the manufacture of terephthalic acid, wherein the wash water includes terephthalic acid, metal catalyst, and organic acid byproducts. The process includes the steps of passing the wash water through a filter medium to remove undissolved terephthalic acid solids, passing the filtered water through a cation exchange resin in hydrogen ion form to remove the metal catalysts, and passing the water through an anion exchange resin to remove dissolved terephthalic acid and dissolved organic acid byproducts. The treated water and certain components removed from the wash water are recovered and reused in the manufacture of additional terephthalic acid. An apparatus in which the process is practiced is also described and, after a quantity of wash water has been treated, the apparatus is regenerated with regenerants that are also recovered and reused in the manufacture of additional terephthalic acid.
