Abstract: Provided are apparatus and systems for performing a swing adsorption process. This swing adsorption process may involve performing dampening for fluctuations in the streams conducted away from the adsorbent bed unit. The process may be utilized for swing adsorption processes, such as rapid cycle TSA and/or rapid cycle PSA, which are utilized to remove one or more contaminants from a gaseous feed stream.

Abstract: A capacitive cable, as well as a method for operating a downhole electro-hydraulic (EH) tool using the capacitive cable, are described herein. The capacitive cable includes at least one standard conductor and at least one capacitive conductor including integrated wire-shaped capacitors. The method includes inserting a tool string including the capacitive cable and an attached downhole EH tool into a wellbore and conducting power from the surface to the downhole EH tool via the standard conductor(s) of the capacitive cable. The method also includes storing electrical energy downhole within the capacitive conductor(s) of the capacitive cable, and activating the downhole EH tool to provide for the rapid release of the electrical energy from the capacitive conductor(s) into the downhole EH tool, initiating an electro-hydraulic event within the wellbore.

Abstract: A process for separating one or more one-ring cycloparaffins and one or more multi-ring cycloparaffins from a hydrocarbon mixture is disclosed. The process comprises the steps of providing the hydrocarbon mixture; and contacting the hydrocarbon mixture with an adsorbent material comprising a metal organic framework to separate the one or more one-ring cycloparaffins and the one or more multi-ring cycloparaffins from the hydrocarbon mixture. The process is conducted in a liquid phase.

Abstract: Systems and methods are provided for integrating a chemical looping combustion system with molten carbonate fuel cells to provide improved operation of the molten carbonate fuel cells when using the exhaust from a gas turbine or other electrical power generation device as the CO2 source for the MCFC cathodes. This integration can be accomplished by using metal oxide in the chemical looping combustion system to oxidize the anode output flow from the MCFCs. This can reduce or minimize the number of separations that need to be performed in order to process the concentrated CO2 present within the anode exhaust. By reducing, minimizing, or eliminating the CO and H2 in the anode exhaust, the need to perform more costly separations (such as cryogenic separation or amine washing) to obtain a high purity CO2 product stream can be reduced or minimized. Optionally, the cathode exhaust from the molten carbonate fuel cells can be used as an oxygen-containing stream for regeneration of the metal oxide.

Abstract: Some examples include systems and methods for monitoring emission indications. A system has an image sensor to capture an image of a flare stack. A computer vision engine is configured to determine whether an emission indicator captured by the image indicates an emission event. A server engine is configured to transmit a notification indicating whether the emission indicator indicates the emission event to a control system of the flare stack. The computer vision engine is configured to update one or more model settings, one or more thresholds, or a combination thereof based on one or more settings. In one embodiment, the computer vision engine is configured to identify, using a deep convolutional neural network (DCNN) model, the emission indicator captured by the image.

Abstract: Disclosed is a staged-air burner device capable of high energy efficiency, high flame stability, combusting multiple readily switchable fuels ranging from pure hydrogen, to any hydrogen/methane mixture, to pure methane, and generating a low level of NOx. The burner device can include: a primary air chamber receiving a primary air and a flue gas; a burner tube capable of receiving a fuel jet and drawing in the air-flue gas mixture from the primary air chamber; a burner tip discharging the fuel-air-flue gas mixture formed in the burner tube to a first combustion zone and a second combustion zone via center orifices and side orifices on the burner tip, respectively; and a staged air chamber receiving staged air and discharging it via staged air ports into a third combustion zone. Combustion of the fuel occurs in at least one of the first, second, and third combustion zones.
