  • Patent number: 10400776
    Abstract: In some aspects, a compressor system includes a compressor train including two or more compressors connected in series and a control mechanism. The control mechanism is controlled by a performance controller. The performance controller is operable to identify a process variable of the performance controller; receive, on a recurrent basis from a load sharing controller, a setpoint for the process variable of the performance controller; and control the control mechanism based on the setpoint and the process variable of the performance controller. The setpoint is determined dynamically during operation of the two or more compressors by the load sharing controller based on a load sharing parameter associated with the two or more compressors.
    Type: Grant

  • Patent number: 9441995
    Abstract: A measurement system and method of use include a fluid conduit for routing a base fluid therethrough, a gas conduit in fluid communication with the fluid conduit for mixing a gas into the base fluid to form a foamed bi-phase fluid, a foam conduit in fluid communication with the fluid conduit and the gas conduit to receive the bi-phase fluid therein, a first sensor disposed to measure a characteristic of the base fluid in the fluid conduit, a second sensor disposed to measure a characteristic of the gas in the gas conduit, a third sensor disposed to measure a characteristic of the bi-phase fluid in the foam conduit, and a processor for receiving data representing the measurement from at least one of the first sensor, the second sensor, and the third sensor, analyzing the data, and calculating a parameter of the bi-phase fluid based upon the data.
