| titleOfInvention | Buffering agents |
| abstract | An improved process for water demineralization involving the use of a first separate column of weakly acidic cation exchange resin, a second separate column of weakly basic anion exchange resin and a third separate column of weakly acidic cation exchange resin. The cation resin is buffered with an at least dihydroxy-substituted amine. When the saline feed is passed through the system, the cations of the feed are exchanged for the buffer, releasing buffered salts. The buffered salts when passed through the anion exchange column are split, releasing the buffer that is then deposited on the third cation resin column. The latter column is then used as the first separate column during the next demineralization cycle. Thus, the buffer is internally looped which prevents contamination of the product water and also resulting in a saving of buffer. This process allows the efficient use of weak cation and anion exchange resins in a separate, fixed-bed configuration. |
