Abstract:
A system for monitoring and controlling exothermic reactions in an ion exchange process comprising:at least one ion exchange unit for treating a liquid containing a composition capable of undergoing an exothermic reaction within the exchange unit; temperature detecting means for detecting the temperature of each of said ion exchange units and for providing a temperature signal from each said unit; monitor means including alarm means for receiving and monitoring the temperature signals from each of said temperature detecting means from each of said temperature detecting means by continuously providing to a data processing means values indicative of the magnitude of the temperature from each said unit; data processing means for processing the temperature signals in a pre-programmed manner, including detecting if one or more of the temperature signals have exceeded pre-established temperature limits which is indicative of an exothermic reaction, and providing control signals to said alarm means; means for introducing an inert fluid into the inlet port of at least one ion exchange unit to quench an exothermic reaction in said liquid and reduce the temperature of the unit, the means for introducing being operatively associated with said alarm means whereby control signals to said alarm means also activates said means for introducing; and means for resetting said data processing means, said alarm means and said means for introducing back to normal configuration when said temperature falls below a predetermined temperature.
