    Abstract: A heat exchange system and process for reducing bleed-off are disclosed employing a weak acid cation exchange resin for treating the aqueous liquid coolant. In one such system and process, the aqueous coolant is treated with a weak acid ion exchange resin to remove alkaline salts therefrom without removing salts of strong acids; suspended solids are removed from the circulating aqueous coolant; and an effective amount of additive selected from the group consisting of scale inhibitors, corrosion inhibitors, microbiocides, and mixtures thereof is introduced into the circulating aqueous coolant so that bleed-off from said system is substantially reduced.

    Abstract: Ion exchange techniques are utilized to treat waste water flows, especially those from plating baths, by passing the waste water through a multi-level ion exchange resin bed, the bed thereafter being regenerated by a series of steps, including backwashing, passage of an acidic regeneration fluid through the bed, multi-stage rinsing of the bed, and passage of a caustic regeneration fluid through at least a portion of the bed. Acidic waste flows developed during regeneration steps are, when desired, further treated to recover cyanide values therefrom by heating same within a generally closed tank to drive off a hydrocyanic gas, which is then reacted with caustic within a circulation reactor having an inclined passageway in order to form and recover a cyanide salt liquor suitable for re-use in the plating bath.

    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: The invention provides a method for removing metal oxides and colloidal material from high-resistivity water streams at a relatively high removal efficiency. The method includes hydrating a highly ionized dual morphology ion exchange resin in a macroreticular, desiccated morphology to produce a macroreticular, hydrated morphology. A water stream which is brought into contact with the resin is purified. The water stream may, optionally, also be contacted with both a cation exchange resin and an anion exchange resin.The invention additionally provides a method for selecting ion exchange resins which are particularly suited for use in removing metal oxides from a condensate stream. The method serves to narrow the field of candidates for pilot-scale resin testing with industrial water streams.
