Abstract: An apparatus and related methods to separate liquid from a liquid/gas mixture, particularly in a low gravity environment. The apparatus includes a chamber having a capillary channel around a perimeter of the chamber, a liquid/gas inlet to the chamber, a liquid outlet from the chamber, the liquid outlet being positioned at the perimeter of the chamber to remove liquid from the capillary channel, and a gas outlet from the chamber. The gas outlet is positioned in the chamber, away from the capillary channel, to remove gas from the chamber. The chamber is structured to be readily fabricated using traditional machining techniques or additive manufacturing techniques. The chamber may be fabricated from various materials, including, for example, polymers, metals, composites, and ceramics. The chamber may function as a heat exchanger so that the apparatus can remove condensable vapors from the gas in the mixture in addition to what is already liquid.

Abstract: Thermal treatment techniques for recycling are generally very clean but their byproducts include a fine ash that may become entrained in the exhaust air plume as smoke. We therefore disclose a materials recycling apparatus (10) comprising a heat treatment chamber (14) for processing the material at an elevated temperature, the chamber having a vent (24) leading via a heat exchanger (26) to a scrubber (36) comprising a disrupted flow path, at least one spray nozzle (54,56,58,60) directed towards the disrupted flow path, and a supply of liquid (ideally water with a little detergent) to the or each spray nozzle. In this way, the entrained ash can be efficiently removed from the air flow, allowing it to be vented, and the captured ash disposed of via a waste water outlet together with the ash washed from the chamber. The flow path can be disrupted by at least one baffle plate (48, 50, 52), ideally with the spray nozzle located ahead of the baffle plate(s).

Abstract: An apparatus to separate water droplets from an air stream includes an elongated tube having a first end and a second end. The elongated tube includes an opening at a first end of the elongated tube, the opening may be positioned to accept the air stream. A reservoir is positioned at a second end of the elongated tube. A helix structure is positioned within the elongated tube. The helix structure includes an upper surface, a lower surface arranged opposite the upper surface, an outer edge, and a variable pitch along a length of the elongated tube. The variable pitch may provide a variable interior angle between an inner wall of the elongated tube and the upper surface of the helix structure.

Abstract: Embodiments of the present disclosure a system for capturing proppant dust particles when positioned at a fracking operation site including a proppant delivery assembly to receive one or more containers having proppant stored therein. The system dispenses the proppant from the one or more containers and delivers the proppant to other fracking operation equipment. Moreover, the system includes a dust collection assembly positioned proximate and associated with the proppant delivery assembly to capture dust particles released by movement and settling of the proppant when being dispensed and delivered by the proppant delivery assembly. The dust collection assembly is positioned to direct an air flow in a flow path overlying the dust particles to capture the dust particles and move the dust particles away from the proppant thereby reducing risk of dust exposure to fracking operation site personnel.

Abstract: High-definition particle detection during centrifugation of a pharmaceutical liquid is provided. Centrifugation of fluid containers drives particles to the interior surface of the container if the particles are denser than the fluid and to the middle of the container if the particles are less dense than the fluid. The imager can then be focused directly on the particle itself for rapid identification without the need for computing complex particle trajectories. If the centrifugation of the container is carried out at an angle to the axis of symmetry of the container, particles can be driven to a single line on the interior surface of the container by the centrifugal force, making the identification of the particles even more straightforward than in two dimensions. The particle imager can also be attached to the rotating container to prevent blurring of the particle image due to the relative motion of the container and imager.

Abstract: The combination of a gas-pressure-driven pump jet nozzle or alternatively Coanda effect nozzle with an impactor nozzle(s) in an air-oil separator for separating oil from blow-by gasses from a crankcase of an internal combustion engine, or for separating liquid aerosol from gas, in general. Such combination enhances impaction efficiency and enables operation at higher pressure differentials (or pressure drop) ("dP") without causing excessive backpressure in the air-oil separator.
