Design provides improved reliability in a polymer-precursor batch reactor. Sensors must respond quickly and survive a harsh environment. Poor probe reliability can make the difference between a process that makes money and one that doesnt.
The more energy prices rise, the more heat integration saves. However, heat integration steps can present complex control problems. Slip-ups in putting control systems in place can make operations nearly impossible. That certainly was the case at one unit using heat recovery.
