Abstract

THE INVENTION RELATES TO A PROCESS FOR CONTINUOUSLY PRODUCING CHLORINE DIOXIDE COMPRISING THE STEPS OF: FEEDING TO A REACTOR AN ACID, A REDUCING AGENT AND ALKALI METAL CHLORATE; REACTING THE ALKALI METAL CHLORATE WITH THE ACID AND THE REDUCING AGENT TO FORM A PRODUCT STREAM CONTAINING CHLORINE DIOXIDE AND THE ALKALI METAL SALT OF THE ACID; AND, BRINGING SAID PRODUCT STREAM FROM THE REACTOR TO AN ABSORPTION TOWER, WHERE IT IS CONTACTED WITH A FLOW OF WATER TO FORM AN AQUEOUS SOLUTION CONTAINING CHLORINE DIOXIDE. THE INVENTION ALSO RELATES TO AN APPARATUS TO PRODUCE CHLORINE DIOXIDE. THE INVENTION FURTHER RELATES TO A NOVEL AQUEOUS SOLUTION COMPRISING OF CHLORINE DIOXIDE.
