Some embodiments relate to an air filter frame including a single strip of framing material forming at least two of the four major frame segments and the frame corner between the two major frame segments. In some embodiments, a single strip of framing material forms at least three of the four major frame segments and two of the frame corners.

Abstract: A method for coalescing a disperse phase component in a primarily gas process fluid includes passing the process fluid through a structure. The structure includes an outer wall with an electrically insulating material formed on an entire inner surface of the outer wall to define an entirely insulated flow path for receiving the process fluid and the flow path is free of any portion of the structure. A plurality of planar, spaced-apart electrode plates is positioned within the entirely insulated flow path and positioned substantially parallel to one another and substantially the entirety of each of the plurality of electrode plates is coated with an insulative material. At least one insulating member disposed in a space between and spaced apart from two adjacent electrode plates. A power source is applied to the electrode plates to generate an electrical field to coalesce droplets of the disperse phase component.

Abstract: A spiral mist elimination system includes a container with an inlet and a layered assembly in fluid communication with the inlet. The layered assembly contains a spiral shape and is concentric with a central axis of the container. The layered assembly imparts centrifugal motion in the engine bleed air as the engine bleed air travels spirally inward. The first portion of the layered assembly receives the first set of droplets. The layered assembly also includes a mesh matrix that collects a second set of droplets. The second set of droplets impacts the mesh matrix and coalesces to form a third set of droplets. A perforated tube is disposed along the central axis of the container. The perforated tube collects the engine bleed air from the layered assembly. Gravity draws the first and third sets of droplets into a reservoir.

When a primary air flow is drawn to flow from the upstream to the downstream positions inside the casing, the primary air flow is adapted to pass by at least one edge of the exterior of the main filter, resulting at least two exterior surfaces of the main filter being exerted with different atmospheric pressures. Through the secondary air flow inlet, a secondary air flow is entrained through the main filter and flows from its exterior surface is exerted with higher atmospheric pressure to its exterior surface is exerted with lower atmospheric pressure.

Abstract: A degasser includes a vessel having a series of chambers. Liquid containing a gas is directed through the vessel and the chambers therein. A stripping gas is injected into the vessel and moves through the vessel in a counter-current direction relative to the flow of liquid. More particularly, the stripping gas moves from one chamber to another chamber in an upstream direction (relative to the flow of the liquid) and is mixed with the liquid in each chamber, causing gas in the liquid to be displaced. Displaced gas is vented from the vessel at a location near where the liquid enters the vessel.
