Abstract
The present invention teaches a process for controlling a continuous gas phase (exothermic) process operating in condensing mode (e.g. polymerization) with a selected temperature for the reactor bed or outlet and with a temperature differential between the reactor inlet and the reactor bed or outlet by controlling the heat transfer provided by the heat exchanger in the recycle line to maintain the selected reactor bed temperature or outlet temperature while simultaneously controlling a condensable liquid feed rate to maintain the temperature differential.
