Specify Control Scheme: Heat Exchanger

7.22. A reactor is cooled by circulating liquid through a heat exchanger that produces low-pressure (10 psig) steam. This steam is then split between a compressor and a turbine. The portion that goes through the turbine drives the compressor. The portion that goes through the compressor is used by 50 psig steam users. 100 p stea ...continues

Specify Control Scheme: Vapor-Phase Reactor

8.14. Overhead vapor from a distillation column passes through a partial condenser. The uncondensed portion is fed into a vapor-phase reactor. The condensed portion is used for reflux in the distillation column. The vapor fed to the reactor can also come from a vaporizer which is fed from a surge tank. To conserve energy, it is ...continues
