  • Patent number: 11513496
    Abstract: A method of monitoring and controlling an industrial process includes capturing images of a non-sensible process condition of the industrial process with an image capture device, receiving the images of the non-sensible process condition with a computer system, and converting each image into a corresponding numeric value with a machine learning model stored in and operable by the computer system. The corresponding numeric value is then received and compared to a predetermined numeric value for the non-sensible process condition with a closed-loop controller, and an actuator operates with the closed-loop controller to adjust operation of the industrial process when the corresponding numeric value fails to match the predetermined numeric value or is outside of a defined threshold near the predetermined numeric value.

  • Publication number: 20210241142
    Abstract: A virtual operation assistant for use in a processing/manufacturing facility (e.g., processing/manufacturing facility) may be an autonomous system that interfaces with a user. The virtual operation assistant may collect real-time and/or historical data about processes and/or hardware in a processing/manufacturing facility, analyze the data, provide reporting and/or recommendations based on the data, execute commands relating to the operational parameters of the processes and/or hardware, and any combination thereof.

  • Patent number: 10133268
    Abstract: Systems and methods for optimizing a system operating in a first mode of operation include detecting an event associated with a cycle in a first mode of operation. When the cycle ends (i.e., when another event is detected), steady state criteria is applied to determine whether data associated with the cycle satisfies the steady state criteria. Optimization targets can be calculated based on the data associated with the cycle. Control signals including the optimization targets can be applied to a next cycle operating in the first mode of operation to improve process performance.

  • Publication number: 20110098862
    Abstract: A method is provided for controlling a multi-stage process. The process comprises multiple first stage processes for producing an intermediate product from a feed, and multiple further stage processes for producing an end-product from the intermediate products. The first stage processes comprise multiple intermediate processes and the further stage processes comprise multiple end processes for producing the end product. An intermediate controller controls the first stage processes in response to one or more product properties of the end product EP and a further controller FC controls the further stage processes in response to the product properties of the intermediate product. The multi-stage process further comprises the step of assigning process values to each of the end processes and the intermediate processes. The intermediate controller IC controls operation of the intermediate processes to optimize the overall process value for producing the end product.

  • Publication number: 20100152900
    Abstract: The present invention is directed to innovative and unique mathematical models that capture key constraints, process kinetics and control structures such that a wide envelope of hydrogen gas and associated light gas supply, distribution and use can be modeled. The present invention is also directed to a real time optimization (RTO) computer application for effective optimization of hydrogen and associated light gas supply and distribution and, thereby, consumption, in a refinery that employs said models and solves an objective function, as well as to a method and refinery using the same. The objective function can be an economic objective function such as the minimization of cost for hydrogen supply and distribution or the maximization of profit based on a valuation of products made by hydrogen consumers in the hydrogen system minus the corresponding cost of the hydrogen supply and distribution.

  • Patent number: 7389186
    Abstract: The invention provides a method and means of predicting, in near real-time, the detailed chemical composition of major streams in a refinery, including those downstream from the crude distillation column. The dynamically updated feed characterizations can be derived in near real time from an assay database of current crude diet, RTO information about upstream refinery units and various analyzer inputs. The chemical compositions of each stream are stored and updated in a plant wide database. A broad range of property calculations can be ascertained, either automatically or on demand, from the compositional information. An application permits users, such as operations, planning and engineering personnel, to access the database directly or indirectly (e.g., on line). This information is then used by each user to further optimize the operation of a given refinery unit and/or the plant as a whole.
