Abstract:
A refinery or petrochemical plant may include a fractionation column and related equipment, such as one or more condensers, receivers, reboilers, feed exchangers, and pumps. The equipment may have boundaries or thresholds of operating parameters based on existing limits and/or operating conditions. Illustrative existing limits may include mechanical pressures, temperature limits, hydraulic pressure limits, and operating lives of various components. There may also be relationships between operational parameters related to particular processes. For example, the boundaries on a naphtha reforming reactor inlet temperature may be dependent on a regenerator capacity and hydrogen-to-hydrocarbon ratio, which in turn may be dependent on a recycle compressor capacity. Operational parameters of a final product may be determined based on actual current or historical operation, and implemented in one or more models to determine adjustments for enhanced operational efficiency.

Claim (Index 17):
A method comprising:\n receiving, by a computing device, surface temperature data collected by one or more thermocouples affixed to one or more tubes inside a furnace of a plant; analyzing, by the computing device, the surface temperature data for completeness by identifying gaps in the surface temperature data based on a measurement interval; correcting, by the computing device, the surface temperature data for overall mass balance closure; using, by the computing device, the surface temperature data to determine whether an upset occurred; based on the surface temperature data for the one or more tubes inside the furnace, determining, by the computing device, a maximum capacity of the furnace; using, by the computing device, a design of a device of the plant to calculate a fraction of an available capacity of the device of the plant that is currently being used; based on the surface temperature data, determining, by the computing device, a model fitting parameter for a process model for a plant; using, by the computing device, the model fitting parameter for the process model for the plant, optimize the process model for the plant; determining, by the computing device, a recommended adjustment to a cut point of the plant or a tray efficiency of the plant to minimize differences between measured performance of the plant and predicted performance of the plant; generating, for display, one or more detail screens depicting a relationship between the surface temperature data and operational performance of the one or more tubes inside the furnace; sending, by the computing device, a report showing actual performance of the plant compared to predicted performance of the plant; and recommending, by the computing device, target operational parameters for the plant to improve production of a final product of the plant.
