Abstract: A liquid droplet catching device installed in a compressor impeller, the device includes an aperture disposed on a surface of the impeller and configured to receive the liquid droplet, and a channel disposed beneath and in fluid communication with the aperture, wherein in the channel is configured to direct the liquid droplet away from the aperture and out of the compressor impeller.

Abstract: A centrifugal compressor comprises at least one stage suited to separate a liquid phase and a gas phase with the aid of at least one of a hydrophobic, super-hydrophobic, hydrophilic or super-hydrophilic surface layer, wherein the hydrophobic and/or super-hydrophobic surface layer is disposed on at least one of an inlet guide vane, impeller, return channel straight hub, or exiting hub bend; and the hydrophilic and/or super-hydrophilic surface is disposed on at least one of the impeller casing, diffuser casing, exiting casing bend, return channel straight hub, exiting hub bend, collection point, or drain.

Abstract: A valve assembly for use in a wellhead assembly that includes a valve body, a cavity formed in the valve body, and a flow passage through the valve body that intersects the cavity. Also included is a gate slidable in the cavity between an open position and a closed position. A bore is formed through the gate. A fluidic passage is also formed through the gates that provides fluid communication between the bore and an upstream side of the valve member. The fluidic passage is formed so that when the gate is being moved into the closed position, fluid upstream of the gate enters the fluidic passage and exits into the bore to assist closing the valve.

Abstract: A system for detecting and controlling a slug event in a flow through a pipeline is provided. The system includes multiple sensors configured to indicate one or more parameters of the flow for a slug at multiple locations in the pipeline. The system also includes a controller configured to receive one or more response signals corresponding to at least one of the parameters from the sensors. The system further includes a variable speed drive system electrically coupled to the controller and a compressor pumping fluid in the pipeline such that a ratio of liquid to gas is within an acceptable range, wherein the variable speed drive is configured to receive one or more signals from the controller and further configured to regulate at least one of a translational or a rotational speed or a power of the compressor based upon the signals. The system also includes a display unit coupled to the controller, the display unit configured to output the plurality of signals received from the controller.

Abstract: A system for stabilizing flow in a pipeline is provided. The system includes at least one of an internal supply or an external supply configured to provide fluid into the pipeline such that a ratio of liquid to gas in the flow is within an acceptable range. The system also includes one or more sensors configured to indicate the ratio of liquid to gas in the fluid. The system further includes at least one valve configured to regulate a flow of the fluid from the internal supply or the external supply into the pipeline based upon the ratio indicated by the one or more sensors.
