Chapter 16, Problem 16.26(choose chapter or problem)
The figure below shows cascade temperature control of a polymerization reactor, which uses feed heat exchange to adjust the reactor temperature. Using the instrumentation diagram, explain how this cascade control system (both master and slave components) handles the following disturbances. (describe what happens to the reactor temperature.) Assume normal temperatures of coolant (70F), polymerization feed (200F), exchanger effluent (100F), and reactor outlet (800F). (a) Feed temperature becomes too high. (b) Feed flow rate becomes too high. Master r----~--------1 Slave Coolant Polymerizer feed Figure E16.26
