Abstract

The method and means of controlling the output of a multi zone reaction installation about a desired conversion level and at optimum performance conditions. An input to the reaction installation is regulated to regulate the severity of reaction in individual zones and such regulation is controlled by means including a regulatable set point for each reaction zone. The discharge effluent from the downstream reaction zone is analyzed and the signal responsive to the character of such effluent is used first to determine a performance index output signal and secondly for determining the total conversion level. An optimizer utilizes the performance index output signal to determine a first output signal for each reaction zone representing a first component of each regulatable set point. The optimizer analyzes the performance index output signal and then determines a first output signal necessary for each reaction zone to approach an optimum performance in the reaction zones. A controller utilizes the signal indicative of the conversion level of the reaction zones and determines a second output signal representing a second component of the regulatable set points corresponding to the desired total conversion level of the reaction zones. The first and second output signals are combined and are utilized as the regulatable set points for controlling the regulation of the severity of reaction in each reaction zone.
