Regeneration of anion exchange resins |
| abstract |
THE INVENTION RELATES TO A METHOD FOR CONVERTING STRONGBASE ANION EXCHANGE RESINS FROM THE MONOVALENT ANION FORM TO THE HYDROXIDE FORM. A SOLUTION OF POLYVALENT ANIONS IS FIRST PASSED THROUGH THE RESIN TO DISPLACE THE MONOVALENT ANIONS. A SOLUTION OF ALKALI METAL HYDROXIDE IS THEN PASSED THROUGH THE RESIN TO CONVERT IT TO THE HYDROXIDE FORM, AND TO PRODUCE AN EFFLUENT SOLUTION OF HYDROXIDE IONS AND POLYVALENT ANIONS. THIS EFFLUENT SOLUTION IS THEN NEUTRALIZED WITH AN ACID CONTAINING POLYVALENT ANIONS, AND THE NEUTRALIZED SOLUTION IS PASSED THROUGH A SECOND BATCH OF RESIN IN THE MONOVALENT ANION FORM. IN THE PREFERRED EMBODIMENT, A PORTION OF THE EFFLUENT IS RETAINED WITHOUT NEUTRALIZATION AND IS DELIVERED TO THE SECOND BATCH OF RESIN AFTER THE NEUTRALIZED EFFLUENT TO PERFORM A PORTION OF THE HYDROXIDE REGENERATION. |
