Abstract: A flare monitoring system includes a camera configured to capture one or more images of a burning portion of a hydrocarbon gas emitted from a flare stack, memory circuitry storing instructions thereon, and processing circuitry configured to execute the instructions to estimate a flow rate of the hydrocarbon gas based on first data corresponding to the one or more images, and based on second data corresponding to an internal diameter of the flare stack.

Abstract: Systems and methods for determining a pump flow (Q) of a pump are disclosed. A method for determining a pump flow (Q) of a pump includes calculating an inverse of a polynomial equation defining a DP-Q performance curve of a pump, where the inverse is a Q-DP polynomial equation defining the performance of the pump, receiving a pump head (DP) value from a pump head sensor associated with the pump, computing a pump flow based on the Q-DP polynomial equation, comparing the computed pump flow to a preset target flow rate, and automatically controlling a pump parameter of the pump such that the calculated flow rate becomes the preset target flow rate.

Abstract: Sales gas output from a glycol dehydration unit in a gas plant is flown into a sales gas pipeline. One or more operational parameters of the glycol dehydration unit are received. One or both of an amount of glycol carryover and an amount of water carryover in sales gas output from the glycol dehydration unit in the gas plant are determined based on the one or more operational parameters of the glycol dehydration unit. An amount of glycol and water co-condensation in the sales gas pipeline is determined based on one or more operational parameters of the sales gas pipeline and the one or both of the amount of glycol carryover and the amount of water carryover. An amount of black powder formation of the sales gas is determined based on the amount of glycol and water co-condensation.

Abstract: A computer-implemented method can include implementing a feedback control scheme including controlling a separation efficiency for a high-pressure production trap (HPPT) by manipulating the demulsifier concentration. Controlling the separation efficiency can include determining, as a function of temperature and based on correlations of historical process data, minimum and maximum target separation efficiencies; identifying a target separation efficiency that is between the minimum and maximum target separation efficiencies; and adjusting a demulsifier dosage, used in calculating the separation efficiency, between a minimum demulsifier concentration and a maximum demulsifier concentration.

Abstract: In a hydrocarbon field including multiple production wells and injection wells, at a hydrocarbon field level, a long-term field-level target and optional long-term well-level targets for the field are received by a field-level processor. The long-term field-level target including a long-term field-level production target indicating a quantity of hydrocarbons to be produced and a long-term field-level injection target indicating a quantity of fluid to be injected into the field. The field-level processor determines short-term individual production targets for the production wells and short-term individual injection targets for the injection wells to achieve the long-term field-level target. At an individual well level, individual hydrocarbon productions of the production wells or individual fluid injections of the injection wells are controlled, by at least one individual well-level processor independent of the field-level processor, to achieve the long-term field-level target.

Abstract: Example computer-implemented methods, apparatuses, and systems are described for implementing split range control using Proportional-Integral (PI) control on a process. In some aspects, a feedback signal from the process is received. A proportional control is performed on the feedback signal to generate a first control output while an integral control is performed on the feedback signal to generate a second control output. A first valve of the process is controlled based on the first control output while a second valve of the process is controlled based on the second control output. The second valve has a valve diameter larger than a valve diameter of the first valve.
