Abstract
The present invention uses a new approach to generating chlorine dioxide. This approach is the use of two vessel system in which the first vessel is of a structure which enables operation to create substantially isothermal incomplete reaction conditions and in which the second vessel is of a structure to enable operation to generate a continuous decreasing temperature gradient from bottom to top thereof for substantially-completing that reaction.
