Abstract
A system for controlling temperature of a polymerization process includes a primary reactor system having a polymerization reactor and a recycle gas line which includes a heat exchanger, a primary temperature controller which continuously measures temperature within the reactor and provides a coolant adjust signal, a secondary cooling system which circulates a mixture of fresh and recirculated coolant through the heat exchanger and a secondary temperature controller which continuously measures the temperature of the mixed coolant and adjusts the proportion of mixed coolant to fresh coolant based on the coolant adjust signal and the temperature of the mixed coolant.
