Per- and polyfluoroalkyl substances (PFAS) are destroyed by oxidation in supercritical conditions. PFAS in water is concentrated in a reverse osmosis step and salt from the resulting solution is removed in supercritical conditions prior to destruction of PFAS in supercritical conditions.

A cyclone includes a hollow cylindrical upper portion and a hollow conical lower portion having an inclined wall and a base wall. The base wall and the inclined wall are continuous contact with each other, and the inclined wall of the hollow conical lower portion is in continuous contact with an outer wall of the hollow cylindrical upper portion. A total cyclone height is from about 10 to about 30 millimeters, and a ratio of the total cyclone height to an inner diameter of the hollow cylindrical upper portion is from about 0.7 to about 1.3. An angle between an inner surface of the base wall and an inner surface of the inclined wall is from about 110 to about 130 degrees.

An accumulator (28), optionally in combination with an internal heat exchanger in a shared housing (24), comprising a cyclone (12) for separation of the gas and liquid phase of a refrigerant, and characterised in that the cyclone (12) comprises two separate, curved flow paths (14, 16), one of which (14) leads from an inlet (18) on the cover side whose direction of flow is closer to the axial than the radial direction of the cyclone (12) into the accumulator and radially outwards, and the other of which (16, 52) leads outwards from an end facing away from the cover (20).

A method and apparatus for a turbine engine having a compressor section, combustion section, and a turbine section in an axial flow arrangement with a cooling circuit in fluid communication with at least one of the compressor section, combustion section, or turbine section. The method and apparatus further including separating particles from a cooling air that flows through the cooling circuit.

Disclosed is a liquid-liquid-solid three-phase separator for waste oil, including an oil-bath heating tank, a plurality of cyclone units and solid removal units. The cyclone units are provided and fixed in the oil-bath heating tank. Each of the solid removal units is connected to an underflow pipe of each of the cyclone units and is configured to separate solid particles. A solid removal outer pipe is arranged at a tail end of the underflow pipe via the first connector; the second connector is arranged at a tail end of the solid removal outer pipe; the solid removal inner pipe is arranged at an underflow outlet of the underflow pipe via the second connector to form a solid removal gap. The invention provides the demulsification and dehydration treatment of waste oil emulsion and the separation of solid particles.

An apparatus for the extraction of compounds from botanical material using a condensable gas solvent includes sequential extraction and separation stages.
