Control of multi reaction zones in response to two qualities of product

Abstract

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 EACH REACTION ZONE IS REGULATED TO CONTROL THE SEVERITY OF REACTION IN THE INDIVIDIUAL ZONES. SUCH REGULATION IS CONTROLLED BY MEANS INCLUDING A REGULATABLE SET POINT FOR EACH REACTION ZONE. THE DISCHARGE EFFUENT FROM THE DOWNSTREAM REACTION ZONE IS ANALYZED AND THE SIGNAL RESPONSIVE TO THE CHARACTER OF SUCH EFFUENT IS USED TO DETERMINE A FIRST AND SECOND QUALITY OF THE EFFUENT STREAM. THE OPTIMIZER RECEIVES A SECOND QUALITY SIGNAL WHICH HAS BEEN MODIFIED BY MEANS WHICH ALTERS THE SIGNAL SENT TO THE OPTIMIZER BY THE EXTENT THAT THE FIRST MEASURED QUALITY HAS DEVIATED FROM A PRESET VALUE. THE OPTIMIZER ANALYZES THE SIGNAL FED TO IT AND THEN DETERMINES A SECOND OUTPUT SIGNAL NECESSARY FOR EACH REACTION ZONE TO APPROACH AN OPTIMUM PERFORMANCE IN THE REACTION ZONES. A CONTROLLER UTILIZES THE SIGNAL INDICATIVE OF THE FIRST QUALITY OF THE EFFUENT AND DETERMINES AN OUTPUT SIGNAL REPRESENTING A FIRST COMPONENT OF THE REGULATABLE SET POINTS. THE FIRST AND SECOND OUTPUTS SIGNALS ARE COMBINED AND ARE UTILIZED AS THE REGULATABLE SET POINTS FOR CONTROLLING THE REGULATION OF THE SEVERITY OF REACTION IN EACH REACTION ZONE.
