In a bubble lift system, a pressurized chamber at an upper end portion of a riser pipe applies a pressure to an upper portion inside the riser pipe to suppress an increase in the volume ratio of bubbles to a fluid mixture rising inside the riser pipe in a shallow water region. The upper end of the riser pipe is not opened to the atmosphere but is inserted into the pressurized chamber under a high pressure to thereby prevent expansion of the bubbles and gas. In addition, a deaerator for discharging bubbles separated by a centrifugal force is also provided in a middle portion of the riser pipe in a shallow water region to distribute the bubbles more evenly inside the whole riser pipe. The bubble lift system and a bubble lift method thus provided are efficient and employable even in a deep water region.

This invention relates to a method and apparatus for recycling plastics, electronics, munitions or propellants. In particular, the method comprises reacting a feed stock with a molten aluminum or aluminum alloy bath. The apparatus includes a reaction vessel for carrying out the reaction, as well as other equipment necessary for capturing and removing the reaction products. Further, the process can be used to cogenerate electricity using the excess heat generated by the process.

A device for separating gas and liquid from a mixture of gas and liquid phases includes a fluid guide member comprising a fluid inlet and a fluid outlet connected by a conduit configured as an elongated spiral disposed about an axis. A liquid coalescing medium is disposed on an exterior surface of the fluid guide radially outward from the elongated spiral conduit with respect to the axis. The separator also includes a plurality of radial channels providing radial flow paths for fluid from the elongated spiral conduit to the coalescing medium.

The present disclosure provides a gas-liquid flow separation system configured to separate a fluid stream containing both gas and liquid components into separate gas and liquid streams. The separation of the components permits the collection of data relating to the volume of each stream. In some embodiments, the separation system provides for the subsequent recombination of the streams in a homogeneous mixture for processing by downstream facilities. Also, the present disclosure provides a manifold system configured to receive fluid streams from a plurality of sources, combine the streams into a single blended stream containing both gas and liquid components. Subsequently, the system provides for separation of the gas from the liquid components and optional recombination of the same.

A method and apparatus are disclosed for separating a multiphase fluid stream that includes a heavier fluid component and a lighter fluid component. The fluid flows along a first helical flowpath with a first pitch. The first helical flowpath is sufficiently long to establish a stabilised rotating fluid flow pattern for the stream. The uniform rotating fluid also flows along a second helical flowpath, the second helical flowpath having a second pitch greater than the first pitch. The lighter fluid is removed from a radially inner region of the second helical flowpath. The method and apparatus are particularly suitable for the separation of oil droplets from water, especially from water for reinjection into a subterranean formation as part of an oil and gas production operation. The method and apparatus are conveniently applied on a modular basis.

A separation tank for crude oil. Fluid enters an inlet section of a center column of the tank via an offset inlet pipe so the fluid enters swirling. Solids that settle in the inlet section are removed by a center column drain and a solids removal system. Free gas rises and exits from the top of the tank. Liquid flows out of the center column via a diffuser that spirals the fluid evenly toward the wall of the tank where oil coalesces and wicks upward. Liquid flows downward around two flow diverting baffles where more oil coalesces and wicks upward via an oil conduit into the oil layer. The water flows under the lower flow diverting baffle and exits the tank through the outlet section. A large circular oil collector weir uniformly removes oil from the oil layer. Interface draw offs located below the oil-water interface remove excess BS&W.

An oil separator provided with a housing with an inlet for an oil-gas mixture and which defines a space that is closed off by means of a lid, whereby a screen is provided in the aforementioned space in which a filter element is affixed and a pipe or collector that connects the interior of the filter element to an outlet in the housing for purified gas, whereby the oil separator is provided with a drainage line for the removal of the oil that has been filtered out, wherein the drainage line ensures the removal of the oil that has been filtered out from the underside of the filter element directly to an outlet for oil in the housing.

The de-aerator can be used to separate air from oil in an aircraft engine lubrication system. The de-aerator can include a swirler cavity extending circumferentially around axis and axially between a proximal wall and a distal wall, a separation path dividing within the swirler cavity into a radially outer oil segment leading to an oil outlet and a radially inner air segment leading to an air outlet, and a swirling conduit portion having a length turning around the axis upstream of an opening in the proximal wall along the separation path.

A gas-liquid separator includes a housing, an inlet in the housing, a flow passage which is in communication with the inlet and through which a water-containing gas supplied through the inlet flows in a vertical direction, a gas-flow director configured to change a flow direction of the water-containing gas flowing through the flow passage from the vertical direction to the horizontal direction, and a gas-liquid separating portion configured to bring the water-containing gas, supplied from the gas-flow director into the housing, into contact with a plurality of separation blades in sequence to separate water from the water-containing gas.

Disclosed are an oil separation structure and a compressor. The oil separation structure includes a housing and a filtering screen. A core is disposed at a center of the housing, and a plurality of guiding members for guiding gas flow are provided along circumferential directions of the core. The filtering screen is disposed on a periphery of the housing, and a cavity is formed between the filtering screen and the core. The housing is provided with a gas inlet and a gas outlet which are in communication with the cavity, and the gas inlet is configured to introduce the gas flow into the cavity; the guiding members are configured to guide the gas flow to rotationally flow around the core, and the gas outlet is configured to discharge the gas flow from the cavity.
