Figure P18.9 shows a CSTR carrying out a liquid-phase, exothermic reaction. The heat released partially vaporizes the contents of the reactor. This vapor is condensed in an external condenser, and the condensate is returned to the reactor. The reactor operates at the boiling point (T and P) of the mixture in the CSTR. The vapor formed consists of reactants and products.

For this system, devise a system to regulate the following variables:

1. Temperature in reactor

2. Residence time in the reactor

Explain how your system would respond to the following changes:

1. Increase in flowrate of feed

2. Fouling of the tubes (on cw side) of the condenser
