Abstract: A chemical conversion process is controlled by calculating the concentration of a reactant within the reactor, such as by means of heat balance computations. The actual concentration of this reactant in the reactor effluent, or in the reactor, is measured by an analyzer. The calculated concentration and the measured concentration are compared, and the resulting signal is employed to control a reaction variable, such as feed rate of a reactant.

Abstract: The flow of catalyst to a polymerization reactor is controlled in response to a computation of the polymer production rate. A signal representative of the computed production rate is passed through a gated derivative controller and divided by a signal representative of the catalyst productivity. The quotient is employed to modify the computer production rate control signal.
