A cyclonic inlet diverter for initiating the separation of a multi-phase inlet fluid flow comprises an enclosed tubular body mounted crosswise within a larger separator vessel. The inlet diverter includes a splitter plate positioned within a center portion of the tubular body and configured to split the inlet flow into a first stream and a second stream, and a swirl plate positioned on each side of the splitter plate with angled surfaces configured to increase the cyclonic motion of the first and second streams within the tubular body. The inlet diverter further includes elongate apertures formed through bottom sidewall portions of the tubular body on each side of the splitter plate, an axial aperture formed through opposing end caps of the tubular body, and at least one radial aperture formed through lateral sidewall portions of the tubular body proximate each opposing end cap.

In one embodiment, a concentrically baffled reactor includes an outer housing that defines an interior space, an inlet through which material can be delivered into the interior space, an outlet through which material can be removed from the interior space, and multiple concentric baffles within the interior space that define multiple concentric reactor zones through which the material can sequentially flow to the outlet.

A separation device for a fluid purification device is provided, the separation device comprising: at least three concentric enclosures including an outermost enclosure and an innermost enclosure and defining at least two concentric cavities; a plurality of spiral-shaped channels formed in each of the at least two concentric cavities, so that fluid can flow through said plurality of spiral-shaped channels; a fluid inlet, for receiving fluid, located in an upper section of an outermost cavity among the at least two concentric cavities, the fluid inlet corresponding to a gas outlet; a solids outlet, for discharging solids comprised in the fluid, located in a lower section of the separation device; and a liquid outlet, for discharging liquid comprised in the fluid, located in an upper section of at least one inner cavity among the at least two concentric cavities.

A separation tank for the separation of a mixture of oil, gas, water, and solids obtained from an oil field includes distinct regions vertically located within the tank interior where constituent components of the mixture can collect. The inflowing mixture may be directed to a vertical column extending inside the separation tank and can be introduced to the tank interior through a swirl vane diffuser configured to impart a helical direction to the inflowing mixture that assist separation of the mixture component. To further facilitate separation of oil from the mixture, the separation tank may be operatively associated with an aeration system configured to generate and introduce an aerated liquid to the tank interior. Gas dissolved in the aerated liquid may form microbubbles that can naturally adhere to the oil and solids separate it from the mixture which can improve the quality of the water.
