Improve Batch Reactor Temperature Control - Emerson

REACTOR TEMPERATURE control typically is very important to product quality, production rate and operating costs. With continuous reactors, the usual objectives are to: • hold temperature within a certain band around the set point, preferably without oscillation; • minimize operator intervention; and • minimize consumption of utilities. Batch reactors generally demand some

of batch reactor temperature control. Although a great deal of work has been done to improve reactor throughput using batch sequence control, the control of the actual reactor temperature remains a difficult problem for many operators of these processes. Temperature control on these systems is difficult for conventional Proportional-Integral-Derivative (PID) controllers because

Automation and Controls for Batch Reactor - ChemEnggHelp

To control the reactor temperature, we provide a temperature control valve in the hot oil cooler by-pass line. In case when reactor temperature goes below set point value, this valve will open to increase the hot oil supply temperature. And for the situation when reactor temperature goes up this by-pass TCV will close down to decrease the hot oil inlet temperature to the

Application of Predictive Control to a Batch Reactor ...

In order to control reaction temperature, cooling is performed by the heat exchanger which utilizes recirculated cooling water. On the other hand, heating is performed by steam, through a serpentine inside the reactor. 3. Objectives. The main objective is to improve reactor temperature control. By this way, a greater efficiency is obtained by:

After a feasibility study, Repsol YPF decided to apply a model-based predictive controller to a batch reactor producing polyols. The predictive controller for reactors (PCR) is a set of control modules that are designed to face most of the reactor configurations. The important increase of production is a consequence of the better handling of the reactor temperature.
