Abstract:
A process for the regeneration of an acid gas absorbent comprising an amine and heat stable salts by phase separation, comprising a) mixing the acid gas absorbent with an alkaline solution, to form a mixture with a pH above the pH equivalence point of the amine; b) cooling the mixture to a temperature below 500 C; c) separating the mixture into a regenerated acid gas absorbent and a waste stream; d) collecting the regenerated acid gas absorbent separate from the waste stream.
Abstract:
The invention relates to a method and a device for converting a preferably weak acid ion-exchange material from the H form into the Ca form, according to which the ion-exchange material is brought into contact with an aqueous, preferably saturated, Ca(OH)2 (calcium hydroxide) solution.
Abstract:
Methods and systems for an integrated acid regeneration of ion exchange resins are disclosed for use in cleaning applications. Acid resins designed for use in a variety of cleaning application using a treated, softened, acidic water source are disclosed. Various methods of using the softened acidic water generated by acid regenerate-able ion exchange resins within a cleaning application, e.g. ware wash machine, are disclosed to beneficially reduce spotting, filming and scale buildup on treated surfaces, reduce and/or eliminate the need for polymers, threshold reagents and/or rinse aids, and using protons generated in the acidic water effluent for triggering events useful in various cleaning applications.

Abstract:
The present invention is generally directed to a versatile fluid treatment system which includes: a mobile device; a track system connected to the mobile device; one or more treatment vessels removably attached to the track system, each treatment vessel comprising a treatment material disposed inside the treatment vessel, at least one fluid inlet, and at least one fluid outlet; an input conduit that receives a fluid to be treated, the input conduit in fluid communication with the fluid inlet on the treatment vessel; and an output conduit in fluid communication with the fluid outlet on the treatment vessel, the output conduit receives treated fluid from the treatment vessels via the fluid outlet.
Abstract:
The present invention provides cationic exchange resin that maintains a high exchange speed of polyvalent ions in addition to monovalent ions without agglomeration occurring in spite of surface coating even when mixed bed ion-exchange resin is used. The cationic exchange resin is modified with a water-soluble cationic polymer electrolyte having an intramolecular cyclic quaternary ammonium salt structure.

Abstract:
A detachable module for optionally recharging sorbent materials, including zirconium phosphate, with an optional bypass and conduits for a sorbent cartridge. The sorbent cartridge can have one or more modules contained therein having connectors connecting each of the modules. One or more of the modules can be reusable and the sorbent materials therein recharged.
