Claim:
1. A method of controlling an exothermic chemical reaction, comprising: measuring a temperature of a first reactant flowing at a first flow rate; subsequently contacting the first reactant with a second reactant flowing at a second flow rate, the contacting occurring under conditions that cause the first and second reactants to react with one another in an exothermic chemical reaction and form a reaction product in a reactor, wherein the reactor is an in-line mixer, the first reactant comprises ammonia, the second reactant comprises sodium hypochlorite, and the reaction product comprises monochloramine, wherein one or both of the first and second reactants are diluted with dilution water; measuring the temperature of the reaction product; determining the temperature difference between the measured temperature of the first reactant and the measured temperature of the reaction product; adjusting the flow rate of at least one of the first reactant and the second reactant if the temperature difference reaches a pre-determined temperature difference; and combining the reaction product with a source of industrial water, process water, cooling tower water, or potable water.
