12. Steady-State Nonisothermal Reactor Design: Flow Reactors with Heat Exchange

Research is to see what everybody else sees, and to think what nobody else has thought.

—Albert Szent-Gyorgyi

Overview. This chapter focuses on chemical reactors with heat exchange. The chapter topics are arranged in the following manner:

• Section 12.1 further develops the energy balance for easy application to PFRs and PBRs.

• Section 12.2 describes PFRs and PBRs for four types of heat exchanger operations.

  1. Constant heat-transfer fluid temperature, T_a

  2. Variable fluid temperature T_a with co-current operation

  3. Variable fluid temperature T_a with countercurrent operation

  4. Adiabatic operation

• Section 12.3 gives examples of four types of heat exchanger operations for PFRs ...
