    Abstract: Provided is an apparatus for recovering amines from amine-containing waste water generated in power stations, etc., and regenerating a cation exchange resin. The apparatus includes: a cation exchange resin layer capturing amines from amine-containing waste water and eluting the amines therefrom; a degassing tower degassing the eluted amines; a vacuum pump connected to the degassing tower; and a condensation and cooling tower condensing the degassed amines at a temperature of −33° C. or lower, wherein the amines captured in the cation exchange resin layer are eluted by injecting a strong acidic solution, while the resin is regenerated, and the amines eluted by the strong acidic solution is subjected to vacuum degassing and then recovered. Provided also is a method for recovering amines and regenerating a cation exchange resin using the apparatus. The apparatus and method for recovering amines and regenerating a cation exchange resin improve the quality of effluent water from power stations, etc., and increase the cost-efficiency through the recycle of amines.

    Abstract: The present invention provides a method for purifying or softening water comprising: passing a specific volume of feedwater through at least one service column comprising a strong acid cationic exchange resin capable of binding divalent cations that are present in the feedwater, wherein the loading of the divalent cations on the resin is restricted to about 1 to 25% of the available ion exchange sites on the resin, and the total dissolved solids in the feedwater is greater than 100 mg/l; feeding the water exiting the service column to a reverse osmosis membrane or a nanofiltration membrane to produce permeate water stream and a reject water stream; and passing all or some of the volume of the reject stream corresponding the specific volume of feedwater through at least one off-line column capable of binding monovalent cations; wherein the chemical equivalent ratio of monovalent to divalent cations in the water exiting the service column is greater than 20 to 1; wherein no external source of regenerant salt is used. The inventive method allows for multiple softening/regeneration cycles so that steady state hardness leakage is achieved that is lower than obtainable with conventional ion exchange softening systems.

    Abstract: Provided is a method for high concentration cation exchange metathesis of divalent ions such as calcium with univalent ions such as sodium or potassium. Due to the difference between ionic valences between the exchanged ions, the provided process behavior is strongly dependent upon the selection of resin properties and to total solution normality. A combination of resin properties and solution normality is provided to achieve the cation exchange.

    Abstract: A method is described that relates to reducing amounts of regenerant waste or increasing the concentration of regenerant waste from ion exchange processes. A method is described that may allow a batch ion exchange process to compete on these factors with continuous or simulated continuous ion exchange processes, and/or to improve the efficiency in operation continuous or simulated continuous ion exchange processes. A specific application addressed is the treatment of water in the Coal Bed Methane Process.
