    摘要： A system for controlling the hydrogen/hydrocarbon mole ratio in a continuous hydrocarbon conversion process wherein the hydrocarbonaceous feed stock is catalytically reacted in a hydrogen atmosphere. Applicable to both hydrogen-consuming and hydrogen-producing processes, in which the reaction zone effluent is separated to provide a liquid product phase and a hydrogen-rich vaporous phase, a portion of the latter being recycled to the catalytic reaction zone, the control system affords improved overall operation of the particular process in addition to increased catalyst activity and stability. Analyzers are utilized to monitor composition characteristics of the charge stock and liquid product, and the hydrogen concentration of the vaporous phase recycled to the reaction zone. Representative output signals are transmitted to comparator/computer means which compares the rate of change and actual values of the composition characteristics and the hydrogen concentration, and generates additional output signals which are utilized within the control system for regulating the hydrogen/hydrocarbon mole ratio of the combined charge to the reaction zone.

    摘要： 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.

    摘要： In a hydrocarbon converting unit in a petroleum refinery, the hydrogen to hydrocarbon mole ratio is controlled in accordance with the following equation: WHERE VH is the volume percent hydrogen in recycle gas, Gg is the specific gravity of the recycle gas, Fg is the flow rate of the recycle gas, Gc is the specific gravity of charge oil, Fc is the charge oil flow rate, Mc is the average molecular weight of the charge oil and the term 13261.21 is a conversion factor. Signal means sample the charge oil and the recycle gas and provide signals corresponding to the specific gravity of the charge oil Gc and of the recycle gas Gg, the average molecular weight Mc of the charge oil and the quantity of hydrogen VH in the recycle gas. Flow transmitters sense the flow rates Fc and Fg of the charge oil and the recycle gas, respectively, and provide corresponding signals. An analog computer computes the hydrogen to hydrocarbon mole ratio in accordance with the aforementioned equation and the signals from the signal means and the flow transmitters and provides an output corresponding thereto. An error signal is developed using an output from the analog computer and a reference signal corresponding to a desired value for the hydrogen to hydrocarbon mole ratio. The error signal is used to control the hydrogen entering the hydrocarbon converting unit so as to maintain the hydrogen to hydrocarbon mole ratio at the desired value.
