  • Patent number: 8333895
    Abstract: A pond receives a flow of contaminated water into the pond substantially tangential to a volume of clarified water which is stored in the pond and which is largely quiescent. The tangential inflow overcomes a large rotational inertia in the stored volume of clarified water and establishes a slow spiral flow path about the periphery of the pond and inwards to a central outlet. The clarified stored water is discharged ahead of the inflowing contaminated water increasing the residence time of the contaminated water in the pond and permitting contaminants to receive at least partial treatment, such as settling of sediment, in the pond.

  • Patent number: 8333239
    Abstract: A burner with a casing seal is used to create a combustion cavity at a temperature sufficient to reservoir sand. The burner creates and sustains hot combustion gases at a steady state for flowing into and permeating through a target zone. The casing seal isolates the combustion cavity from the cased wellbore and forms a sealed casing annulus between the cased wellbore and the burner. Water is injected into the target zone, above the combustion cavity, through the sealed casing annulus. The injected water permeates laterally and cools the reservoir adjacent the wellbore, and the wellbore from the heat of the hot combustion gases. The hot combustion gases and the water in the reservoir interact to form a drive front in a hydrocarbon reservoir.

  • Patent number: 8197676
    Abstract: A tailings solvent recovery vessel substantially without conventional internals utilizes nozzles for forming very fine solvent-containing hydrocarbon droplets from a solvent-containing tailings feedstream. The hydrocarbon droplets are discrete from water droplets. The hydrocarbon droplets are small enough to result in a large surface area and a desired fall residence time but sufficiently large that they are not entrained with the rising vapor in the vessel. The feedstream is introduced to the vessel with a pressure drop to result in an initial flashing of the solvent from the solvent-containing droplets. Heat from the vessel atmosphere or from steam flowing countercurrent to the falling hydrocarbon droplets is transferred to the falling hydrocarbon droplets resulting in vaporization of any residual solvent therefrom. A substantially solvent-depleted pool is collected in the bottom of the vessel and retained only so long as is required to pump the underflow stream from the vessel.

  • Patent number: 8122949
    Abstract: A tapered sleeve and fracturing head system for introducing fracturing fluid to a wellbore, while protecting a conveyance string from the erosive effects of the fracturing fluid is disclosed. A tapered sleeve has a top portion and a tapered downhole portion. The sleeve is fit to a main bore of a fracturing head by an upset at the top portion of the sleeve that engages a shoulder of the fracturing head. The sleeve intercepts, deflects and redirects introduced fracturing fluids downhole, preventing direct impingement of the fracturing fluid against the conveyance string. The main bore of the fracturing head may also be tapered at an angle substantial parallel to and along the length of the taper of the sleeve, to further improve the fluid dynamics of the fracturing fluid and further reduce the erosive effects of the fracturing fluid.

  • Patent number: 7936920
    Abstract: Relative histograms compare occurrences in event channels for a multi-channel data set for determining comparisons therebetween. One or more relative histograms are formed using relating functions applied to channels, preferably including a quotient between a first reference channel and a second channel and between the reference channel and at least a third channel. Preferably the relating functions generate values where a ratio and its reciprocal are symmetrical about an identity value. More preferably a data set is presented in a two-dimensional histogram for establishing the deviation of significant counts from an adjustment point which is preferably at the identity value. In practice, the relative histograms can be applied to correct tint in the red, green and blue channels of color images.

  • Patent number: 7927394
    Abstract: Collection apparatus are installed in a horizontal separator vessel to aid conventional coalescing media to remove mist and droplets from a gas flow, typically downstream from a compressor. The collection apparatus have filaments which act to wick the coalesced droplets either from the conventional coalescing media or from the sides of the vessel toward an annular channel which collects the droplets and assists in delivering the droplets, by gravity, to the bottom of horizontal vessel where they are carried to a collection area. Use of the collection apparatus permits a reduction in the size of the separator vessel and further permits vapor load factors of up to about 10 times that in a conventionally designed separator vessel.

  • Patent number: 7909975
    Abstract: Disclosed is a system for recovering gas produced during electrodialysis of a saline solution, from gas entrained in an electrolyte solution circulating through anode and cathode compartments of an electrodialysis (ED) unit. In one embodiment, the system provides separate catholyte and anolyte towers within a closed, re-circulating loop between the cathode and anode compartments. Each tower comprises an inlet at which the entrained gas separates from the electrolyte solution and flows into the headspace. One can recover residual gases from the electrolyte solution in one more additional apparatus. Preferably, hydrogen gas is separated from the catholyte solution and, more preferably, further purified for use as a fuel source in alternative power generating devices, such as a fuel cell or bio-fuel generator, useful in the unit operations of a water treatment system.

  • Patent number: 7754661
    Abstract: A method of recovering hydrocarbon or synthetic base oils from used oil-based drilling mud utilizes acid to deactivate emulsifiers in the drilling mud for altering the emulsion stability and permitting removal of the solids contained in the drilling mud using conventional separation such as centrifugation. A surfactant is typically added to prevent water-wetting as a result of the addition of the acid. The recovered base oil contains substantially all of the deactivated emulsifiers, which can be reactivated through the addition of lime, allowing new drilling fluids to be prepared without the need to add significant amounts of emulsifier to the recycled base oil.
