    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.

    The present invention relates to methods for controlling the conversion process in series-connected reactors and can be used in the chemical industry. A known method of controlling the conversion process in series-connected reactors by influencing the temperature in each reactor depending on the quality indicators of the products after each reactor 1. A disadvantage of the known method is that when it is used, the potential yield of the desired product is not achieved. The purpose of the invention is to increase the yield of the target product. This goal is achieved by the fact that, in the proposed invention, the effect on the temperature in each of the reactors: additionally realizes the dependence of the content of the target product and reaction by-products on the output of the last reactor. The drawing shows the implementation of the method of managing the conversion process. The conversion process is carried out in series-connected reactors 1 and 2, the feed streams of which are heated in heating apparatus 3 and 4 (furnaces or heat exchangers). The raw materials and products of the reactors are transported through lines 5, 6, 7, 8; heat (fuel or coolant) is supplied to the heaters through pipelines 9 and 10. Fuel controllers (or heat carrier) 11 and 12 are installed to control the heat supply on these pipelines; temperature controllers 13, 14 are used to control the temperature in reactors; The system also includes a compositional analyzer of the reaction mixture at the outlet of the chain of reactors 15, a regulator of the composition of product 16, a computing device 17, an optimizer 18, adders 19, 20. The system works so that, depending on the deviation of the ratio between the content of the target product and side reaction products from a predetermined value, the composition regulator of the product 16 acts on the settings of the temperature regulators in reactors 13 and 14 through the adders 19 and 20, and the temperature regulators act on the settings of the fuel consumption regulators Willow 11 and 12 for heating reactors. At the same time, the computing device 17 indirectly monitors the process indicator, depending on which deviation from the optimal value, the optimizer 18 changes the operating modes of the reactors by influencing the tasks of temperature regulators 13 and 14.
