    Abstract: An apparatus, method, and system for recovering oil from a submerged oil source, wherein the system includes a submerged conduit having at least two openings, with a first opening capable of being located in proximity of a leak in order to capture leaking oil, and with a second opening capable of communicating captured leaking oil to another location. A natural gas separator, coupled to the submerged conduit separates the boiling vapor phase natural gas from the captured oil thereby outputting oil with water contaminant. An oil/water separator coupled to the natural gas separator then separates out the contaminant water, resulting in a processed recovered oil product for storage and subsequent refinement. The flow to capture the leak is induced by generating a lower pressure at nozzle in the conduit via power jet, air lift, pumping of fluid out of conduit close to sea level, or other methods.

  • Publication number: 20130220629
    Abstract: A two phase gas-liquid separation apparatus is provided that shapes the flow in a flow shaping line. Shaping the two-phase flow allows centrifugal force to send the heavier, denser liquid to the outside wall of the flow shaping line and allows the lighter, less dense vapor or gas to occupy the inner wall of the flow shaping line. With the gas positioned on the inner wall of the flow shaping line, an exit port on the inner wall will allow for the majority, if not all, of the gas, along with a low amount of liquid, to be sent to a conventional separator. A high ratio of vapor/liquid at a flow rate much lower than the total flow rate within the flow shaping line is sent to the conventional separator. This allows for efficient separation of the vapor from the liquid with the use of a smaller conventional separator.

  • Patent number: 8366808
    Abstract: A method and apparatus for separating a first fluid from a fluid mixture. In one embodiment water containing methane is passed through an agitation chamber with a plate at the chamber's proximal and distal ends. Both plates have orifices permitting the mixed fluid to pass into and out of the agitation chamber. In one embodiment, the mixed fluid rotates about its axis of flow through the agitation chamber. In one embodiment, the mixed fluid passes through a separation chamber having a plurality of baffles that promote separation of the methane from the methane/water mixture. In one embodiment, the separated methane is removed from the water in a collection chamber that facilitates gravity separation of the mixed fluids. In one embodiment, liquid hydrocarbon is removed from water.

  • Patent number: 8333828
    Abstract: Various embodiments of the present invention are directed to degassing and cleaning of hydrocarbon fuel. Degassing of hydrocarbon fuel is a way to remove the dissolved gases which aid in the oxidation of the fuel as well as the removal of sulfur, water and other particulate matter through radial cavitation. This process allows for both improvements in efficiency as well as decrease in emissions of standard fuel and the re-refining of fuels which have broken down. University of Idaho did a study on the breakdown of diesel fuel and found out that 26% of the efficiency is lost by the 28th day after fuel processing. In one embodiment, the fuel is subjected to fluid-shear forces and cavitation.

  • Publication number: 20120118154
    Abstract: A process and apparatus is provided for reduction of dissolved oxygen content in seawater from about 8 ppm in the feed seawater to about 10 ppb or less. Significant advantages are achieved by: use of a separator in horizontal alignment to provide high gas-liquid contacting area for separation and de-entrainment within the separator, thereby providing higher throughput; and heating seawater to at least 30° C. and up to 60° C., so as to enhance removal of oxygen from seawater; use of once-through fuel gas as stripping gas and its subsequent combustion for heating the seawater provides for high efficiency and reduction of fouling. The combination of these features allows the amount of residual oxygen in deoxygenated seawater to be reduced to below 10 ppb and as low as 2 ppb.

  • Patent number: RE43941
    Abstract: An apparatus for separating natural gas from production streams comprising a liquid dispersion of water, sand, and natural gas is provided for. The separator comprises a vessel having an interior surface defining a spherical interior space. The interior space allows a production stream introduced therein to experience a velocity drop sufficient to allow separation of the natural gas from the sand and water components. The separator also comprises a stream inlet port in the vessel, a liquid drain in the lower end of the vessel, and a gas outlet port at the upper end of the vessel remote from the stream inlet port. A baffle is mounted in the interior of the vessel in the path of the production stream between the stream inlet port and the gas outlet port. The baffle is effective to spread and direct a high pressure production stream introduced into the interior space via the stream inlet port downward toward the liquid drain.
