Chlorine dioxide production

Claim 1

A CONTINUOUS PROCESS FOR PRODUCING GASEOUS CHLORINE DIOXIDE AND CHLORINE IN AN APPROXIMATE TWO TO ONE MOLAR RATO BY THE REACTION OF A CHLORATE AND A CHLORIDE IN A STRONG ACID SOLUTION, WHICH COMPRISES: MAINTAINING A CONSTANT LEVEL IN A SINGLE REACTOR CONTAINING A GENERATING SOLUTION SELECTED FROM THE GROUP CONSISTING OF (A) A SOLUTION WHICH IS 3.5 TO 6.5 MOLAR IN SULFURIC ACID, 0.5 TO 0.01 MOLAR IN CHLORATE AND 0.3 TO 0.001 MOLAR IN CHLORIDE, AND (B) A SOLUTION WHICH IS 7.5 TO 15 MOLAR IN PHOSPHORIC ACID, 0.5 TO 0.1 MOLAR IN CHLORATE, AND 0.3 TO 0.001 MOLAR IN CHLORIDE; CONTINUOUSLY ADDING A SUBSTANTIALLY EQUIMOLAR RATIO OF CHLORATE AND CHLORIDE IONS, IN A MOLAR CONCENTRATION GREATER THAN THE MAXIMUM IN THE GENERATING SOLUTION AND AT A RATE STOICHIOMETRICALLY EQUIVALENT TO THE AMOUNT OF CHLORINE DIOXIDE AND CHLORINE PRODUCED; CONTINUOUSLY ADDING AN APPROPRIATE ACID, SELECTED FROM THE GROUP CONSISTING OF SULFURIC ACID AND PHOSPHORIC ACID, IN A MOLAR CONCENTRATION GREATER THAN THAT OF THE ACID IN THE GENERATING SOLUTION AND AT A RATE SUCH THAT THE CONCENTRATION OF ACID IN THE GENERATING SOLUTION REMAINS RELATIVELY CONSTANT, THEREBY MAINTAINING THE COMPOSITION OF THE GENERATING SOLUTION WITHIN THE REACTOR RELATIVELY CONSTANT; CONTINUOUSLY REMOVING THE EXCESS SOLUTION FROM THE REACTOR, THUS MAINTAINING THE LEVEL OF THE SOLUTION WITHIN THE REACTOR CONSTANT; AND, CONTINUOUSLY REMOVING THE CHLORINE DIOXIDE AND CHLORINE THUS PRODUCED.
