Title: Improvements in or relating to process of regenerating an exhausted mixed-bed ion-exchange column
IPC: B01J47/04
Filed: 1950-09-08
Abstract: 681,411. Regeneration of ion-exchange material. ROHM & HAAS CO. Sept. 8, 1950 [Sept. 16, 1949; Aug. 24, 1950], No. 22172/50. Class 46 A process of regenerating an exhausted mixed-bed ion-exchange 'column containing an anion-exchange resin and a cation-exchange resin having a differ-. ence in density of at least 1 gram per cent. comprises passing water through the exhausted column to stratify the ,bed into upper and lower layers of different resins, passing regenerant solutions through the respective layers and finally remixing the regenerated layers. In the arrangement shown, a container 1 is charged with cation-exchange material and anion-exchange material. For the process of ionexchange treatment the exchangers are covered with water 4 and are thoroughly mixed by passing air under pressure through an inlet 7, the air escaping through a vent 8. The water is then drained to the level of the bed. The fluid to be de-ionized is introduced into the tank through inlet 10 and removed as effuent from pipe 9. When the bed is exhausted Water is passed up through pipe 9 at a fairly rapid rate so that the ion-exchangers form two different layers 2, 3. An alkali solution is admitted through inlet 10 and passed through layers 2, 3, until the bed 3 has been regenerated. Then a solution of a strong mineral acid is passed through pipe 11, which extends to, or very slightly below, the interface 6 of the layers 2, 3. When regeneration is completed water and then air are admitted to loosen and mix the beds. Instead of pipe 11 inlets may be placed around the tank 1 at the level 6. The cation-exchange materials which can be used includes sulphonated or sulphated resin insoluble resins containing the carboxy and carbonaceous group zeolites which contain sulphonate and/or carboxy groups. The sulphonated or sulphated resins include those prepared from phenols and formaldehyde or catichol-type tannins and formaldehyde together with sulphates, or from phenol-formaldehyde condensates, which contain sulphonated groups. Another type of sulphonated resin is prepared through isopolyrnerization of a vinyl hydrocarbon, for example styrene, with a cross-linking agent such as divinylbenzene, followed by sulphonation of the copolymer. Carboxy containing resins are obtained by forming a copolymer or a heteropolymer with a carboxylic acid or an acid anhydride such as maleic an hydride and a cross-linking agent such as a polyvinyl compound. The anion exchange resins are reaction products of an amine and a halomethylated, mixable cross-linked copolymer of a monovinyl hydrocarbon and a polyvinyl compound.
