Consider the CSTR in Figure Q7.1. No product is present in the feed stream, a single chemical reaction occurs in the reactor, and the heat of reaction is zero. Determine whether each of the following single-loop control designs is possible. Consider each question separately. Control the product concentration in the reactor by adjusting the valve in the pure A pipe. Control the product concentration in the reactor by adjusting the valve in the coolant flow pipe. Control the product concentration in the reactor by adjusting the valve in the solvent pipe. Control the temperature in the reactor by adjusting the valve in the pure A pipe. Control the temperature in the reactor by adjusting the valve in the coolant flow pipe. Control the temperature in the reactor by adjusting the valve in the solvent pipe.
