A polymer is produced by the emulsion polymerization of acrylonitrile and methyl methacrylate in a stirred vessel. The monomers and an aqueous solution of catalyst are fed to the polymerization reactor continuously. The product is withdrawn from the base of the vessel as a slurry.

Devise a control system for this reactor, and draw up a preliminary piping and instrument diagram. The following points need to be considered:

1. Close control of the reactor temperature is required.

2. The reactor runs 90% full.

3. The water and monomers are fed to the reactor separately.

4. The emulsion is a 30% mixture of monomers in water.

5. The flow of catalyst will be small compared with the water and monomer flows.

6. Accurate control of the catalyst flow is essential.
