Abstract
A control apparatus for a tubular polymerization reactor having a feed line for a raw material to be polymerized, a cooling circuit for cooling the reactor with a flow of coolant and exit line for a product polymerization, comprises a quality sensor for sensing the actual quality of the product in the exit line, a quality controller for receiving a desired product quality set point and comparing it with the actual quality of the product to generate a desired temperature value for the reactor, temperature sensors for determining the maximum temperature of the reactor and a temperature controller for controlling the amount of coolant supplied to the reactor by the cooling circuit. The temperature controller compares the maximum temperature of the reactor with a desired temperature value therefor corresponding to the desired quantity to control the cooling circuit accordingly. A production rate controller is also provided which controls the rate of production by regulating the amount of raw material flow to the reactor as a function of the concentration of raw material in the exit line from the reactor. The amount of catalyst supplied to the feed line is regulated as a function of raw material concentration of the feed line or flow of raw material in the feed line. The control apparatus also optimizes the process by maximizing reactor temperature, catalyst flow rate, coolant flow rate, reactor exit temperature and maximum polymerization in the reactor.
