  • Patent number: 8580011
    Abstract: A gas and liquid mixture separation and collection system for zero gravity operation that can be applied to a urinal toilet is disclosed. There is an inlet to receive the gas and liquid mixture. The mixture is directed to a filter having an air side. A vacuum pump on the air side of the filter generates a pressure delta to force the inlet flow. A peristaltic pump is used to transfer liquid away from the filter surface. In doing so, the flow on the liquid side of the membrane filter may contain some gas left over from the inlet flow mixture, but there is substantially less gas than in the gas and liquid mixture at the inlet. The filtered mixture is directed to an expandable collection bag that is attached to the air side of the filter so the filter process can be repeated to remove more gas from the mixture.

The separator includes an upper-tier elongate conduit, a lower-tier elongate conduit and a plurality of spaced apart connectors. Each of the upper and lower-tier elongate conduits has an outlet and at least one of the upper and lower-tier elongate conduits has an inlet for receiving the mixture flow. The upper and lower-tier elongate conduits also each have a plurality of openings such that one connector of the plurality of connectors may interconnect one of the upper-tier elongate conduit openings with a one of the lower-tier elongate conduit openings. The connectors enable communication of at least one of a liquid component and the at least one of another liquid component and a gas component of the mixture flow therebetween.

  • Patent number: 7615103
    Abstract: The present invention is directed to methods and apparatuses for removing bubbles from a process liquid. The process liquid can comprise a plating solution used in a plating tool. The process liquid is supplied to a tank. A plurality of streams of the process liquid are directed towards a surface of the process liquid from below. This can be done by feeding the process liquid to a flow distributor comprising a plurality of openings providing flow communication between an inner volume of the flow distributor and a main volume of the tank. Before leaving the tank through an outlet, the process liquid flows through a flow barrier.

  • Patent number: 7569097
    Abstract: In subsea multiphase pumping systems, the use of a gas-liquid cylindrical cyclone (GLCC) as a separator to recirculate liquid from pump discharge to pump suction, especially during high gas inlet conditions from a multiphase petroleum stream. Further contemplated is protection of the pump from momentary high gas inlet conditions due to an incoming slug flow profile from a petroleum stream, via transforming a naturally varying multiphase petroleum stream into separated phases for measured distribution to the pump suction and ensuring a minimum liquid flow.

  • Patent number: 6893486
    Abstract: A method and system for sea-based handling/treatment of fluid hydrocarbons (oil) with associated gas include a first separation step in a high-pressure separator (18) installed on the sea bed, from which is output an oil flow containing an essentially predefined percentage of residual gas. The oil containing residual gas is carried through a riser (22) up to a surface vessel/production ship (12), where it is subjected to a second separation step in a second separator (24) incorporated in a low-pressure surface plant on board the vessel (12), this separated residual gas being used as fuel for direct/indirect generation of electric power for the operation of the underwater and above-water sections of the system. Water and gas produced in the first separation step is returned to a suitable reservoir by the use of a multiphase pump.

  • Patent number: 6726743
    Abstract: This disclosure relates to a method for deaerating a liquid layer such as a coating solution using electrostatic forces. A flow of charged particles is created above and moved towards a low conductivity liquid layer. The flow of charged particles causes localized thinning of the liquid layer which facilitates the removal of bubbles of entrained gas from the liquid by bringing those bubbles closer to the exposed surface of the liquid and rupturing them at that surface. This electrostatic deaeration technique is combined with other non-electrostatic liquid layer thinning techniques or degassing techniques to further facilitate removal of bubbles from the liquid in preparation of further processing of the liquid. The liquid layer may be stationary or flowing with respect to the application of charge particles.

  • Patent number: 6630013
    Abstract: An apparatus and method for deaeration of treatment agents applied to webs of paper and board, having an inlet manifold (3), an accept-fraction manifold (4), and a reject-fraction manifold (5). For deaeration the assembly uses a plurality of air separator units (12) connected to the manifolds so as to allow admission of the treatment agent to the air separator units (12) from the inlet manifold (3) and discharge of the accept and reject fractions formed in the air separator units (12) respectively to the accept-fraction and reject-fraction manifolds (4, 5). A cut-off valve (18) is mounted on at least the inlet manifold (3), between two parallel-operating air separator units (12), so as to permit cutting off the flow through the manifold (3) at this location of the cut-off valve, dividing the plural air separator units (12) by the cut-off valve (18) into two groups.
