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.

Abstract: An in situ recovery of uranium operation involves circulating reactive fluids through an underground uranium deposit. These fluids contain chemicals that dissolve the uranium ore. Uranium is recovered from the fluids after they are pumped back to the surface. Chemicals used to accomplish this include complexing agents that are organic, readily degradable, and/or have a predictable lifetime in an aquifer. Efficiency is increased through development of organic agents targeted to complexing tetravalent uranium rather than hexavalent uranium. The operation provides for in situ immobilization of some oxy-anion pollutants under oxidizing conditions as well as reducing conditions. The operation also artificially reestablishes reducing conditions on the aquifer after uranium recovery is completed. With the ability to have the impacted aquifer reliably remediated, the uranium recovery operation can be considered inherently safe.

Abstract: A debris catcher uses induced circulation from a venturi to urge debris laden flow into the lower end of a housing. An inlet tube maintains velocity so as to keep the debris moving with the fluid stream as it goes up the inlet tube. A screen fits over the open end of the inlet tube and runs down around the inlet tube toward the entrance of the debris laden fluid into the lower end of the housing. There is a clearance around the cylindrical portion of the screen so some flow can exit that way. There is also an open exit through the top of the screen that can be reached after the fluid stream makes two hairpin turns. Many modules can be stacked. Each module has a large screen area for flow to exit and progressive modules can have smaller screen openings in an uphole flow direction.

Abstract: The acid mine water demineralization apparatus consists of two concentric cylinders that are divided into a total of four sections; a water chamber, a gas chamber, a reaction zone, and an aeration zone. The water chamber transports acid mine water to the inlets of a plurality of the sharp edged orifices. The gas chamber receives ozone from an external source and sends it through a porous plate into the reaction zone, thus ensuring the gas is dispersed uniformly throughout the reaction zone. Water passing through the sharp edged orifices into the reaction zone reacts with the ozone to oxidize the insoluble metals in the water. Exiting the reaction zone, the water enters into the aeration zone where additional oxygen is added to the water and the agitation of the water is calmed before it enters a settling tank.
