Abstract: A process for something separating oxygen from air includes mixing the air with hydro fluoro ether in a closed vessel for a desired period of time so that the oxygen from the air is adsorbed into the hydro fluoro ether, discharging the oxygen-adsorbed hydro fluoro ether from the closed vessel, and flashing the oxygen-adsorbed hydro fluoro ether into a chamber so that so as to separate the oxygen from the hydro fluoro ether. Nitrogen is separated from the air as the oxygen is adsorbed in the hydro fluoro ether in the closed vessel. The step of flashing that includes passing the elevated pressure oxygen-adsorbed hydro fluoro ether across a restricting orifice so as to evaporate the oxygen from the hydro fluoro ether.

Abstract: A stacked-plate apparatus and method for separating a first fluid from a multiphase fluid, the apparatus having pairs of adjacent plates spaced apart from one another to form gaps, or flow passageways, between the plates. At a selected pressure, the first fluid of the multiphase fluid can flow along the gaps between the plates, to be collected when it exits the gaps. The other fluids of the multiphase fluid cannot flow along the gaps, and thus the first fluid is separated from the second fluid. The method and apparatus can be used to separate fluids that have different rheological properties, such as air and water, or water and oil.

Abstract: An inlet device for use in a vessel to facilitate separation of a gas phase from a liquid phase in a fluid stream. The inlet device has separation cans positioned at each of the outlet ends of a flow channel. Each separation can has a cylindrical wall and an elongated inlet opening in the cylindrical wall to allow the fluid stream to be introduced in a tangential direction into an open interior region where it swirls to facilitate separation of the gas phase from the liquid phase in the fluid stream. The liquid phase exits the separation can through slots in the cylindrical wall and through an open lower end of the open interior region. The gas phase exits the separation can by ascending upwardly through an open upper end of the open interior region.

Abstract: The present invention relates to processes and systems for basic gas, e.g., ammonia, recovery and/or acid-gas separation. In some embodiments, a system for acid gas separation may be integrated with an ammonia abatement cycle employing a high temperature absorber. In some embodiments, a system for acid gas separation may employ a higher temperature absorber due to the lower energy consumption and cost of the integrated ammonia abatement cycle. Advantageously, heat may be recovered from the absorber to power at least a portion of any acid gas desorption in the process. Reverse osmosis or other membranes may be employed.
