| titleOfInvention | METHOD AND APPARATUS FOR CONTROLLING IMPURITIES AND POLLUTION FOR MEMBRANE ALKALINE CHLORIDE CELLS |
| abstract | A.PROCESS AND APPARATUS FOR THE ELECTROLYSIS OF AN AQUEOUS SOLUTION 101 OF ALKALINE METAL IN 106 CELLS INCLUDING COMPARTMENTS OF CATHODE 106C AND ANODE 106A SEPARATED BY A MEMBRANE 106M IMPERMEABLE TO FLUIDS BUT SELECTIVELY PERMEABLE TO CATIONS. B. PROCESS CHARACTERIZED IN THAT IT CONSISTS OF MIXING A SATURATED SOLUTION OF METAL CHLORIDE WITH PHOSPHORIC ACID OR ALKALINE PHOSPHATES OR CARBONATES, TO ADJUST THE PH TO APPROXIMATELY 10 TO PRECIPITATE THE NON-MONOVALENT CATIONS, TO KEEP AT 2P THE CHLORIDE CONCENTRATION OF THE SOLUTION BY PASSING IT THROUGH A CATION EXCHANGER 103 TO PASS THE SOLUTION THROUGH THE ANODE COMPARTMENTS MAINTAINING THE PH AT APPROXIMATELY 2 BY THE HYDROCHLORIC ACID PRODUCED IN THE SYSTEM, THE CONCENTRATION OF ALKALINE HYDROXIDE AT APPROXIMATELY 8 AND THE TEMPERATURE AT APPROXIMATELY 70C, TO RECOVER CHLORINE AND TO RESTORE AND RECYCLE LIQUID CHLORINE. C. THE INVENTION APPLIES TO THE PRODUCTION OF CHLORINE AND ALKALINE HYDROXIDES. |
