    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.

    Abstract: The invention provides a method for removing transition metal oxides and soluble cation species from condensate at a relatively high removal efficiency. The method includes hydrating a strongly acidic dual morphology cation exchange resin in a macroeticular, desiccated morphology to produce a macroreticular, hydrated morphology. Condensate which is brought into contact with the resin when it is in a hydrogen form is purified. The condensate may, optionally, also be contacted with an anion exchange resin.The invention additionally provides a method for selecting cation exchange resins which are particularly suited for use in removing metal oxides from a condensate stream. The method serves to narrow the field of condidates for pilot-scale resin testing with industrial condensate.

    Abstract: An apparatus and method for removing particulates, hydrcarbons (such as oil), cations and anions including nitrite ions from a liquid, such as an engine coolant liquid having a freezing point depressant and situated in an internal combination engine cooling system. The apparatus has at least one filter for removing particulates and hydrocarbons; a strong acid cation exchange bed in the hydrogen form for removing cations; a strong base anion exchange bed in the hydroxide form for removing anions; and separator for separating gas containing nitrogen, such as nitric oxide and/or nitrogen dioxide, that is produced in the cation exchange bed and/or the anion exchange bed. The method for removing particulates, hydrocarbons, cations, anions and nitrite ions from an engine coolant liquid having a freezing point depressant comprises providing an engine coolant liquid having particulates, hydrocarbons, cations, anions and nitrite ions; passing the engine coolant liquid through a zone for filtering wherein particulates and hydrocarbons are removed from the engine coolant liquid; and passing the engine coolant liquid through a strong acid cation exchanger bed in the hydrogen form wherein cations are removed from the engine coolant liquid and nitrite ions are converted into nitric oxide and/or nitrogen dioxide. The method further comprises passing the engine coolant liquid through a strong base anion exchanger bed in the hydroxide form wherein anions are removed from the engine coolant liquid; and subsequently separating the nitric oxide and/or nitrogen dioxide from the engine coolant liquid to produce an engine coolant liquid having the freezing point depressant.

    Abstract: Ion exchange resin beds used for ammonia-cycle condensate polishing show enhanced selectivity for sodium ions over ammonium ions when conventional, monosulfonated cation exchange resin is replaced with polysulfonated cation exchange resin. This enhanced selectivity results in a lower concentration of sodium ion leakage and longer bed life to critical leakage, compared with conventional, monosulfonated resins.

    Abstract: A method and system combining filtration and ion-exchange structures for removing contaminants from liquids. In overall concept, contaminated liquid is passed through filtering mediums to remove particulate matter from the incoming contaminated liquid. Organics are removed from the liquid by passage through adsorbent non-ionic type resins. The liquid is then passed through strong acid cation exchange resins, weak base anion exchange resins, weak acid cation exchange resins, and strong base anion exchange resins arranged in a predetermined location in the liquid flow path to provide optimized contaminant removal. One of the optimization techniques is through the pH adjustment of the liquid at predetermined points in the flow path. Additionally, the liquid to be purified is passed through mixed bed polisher resins as well as chelation resins to provide a final substantially contaminant free liquid which is returned to use in a closed loop fashion.
