  • Patent number: 10710916
    Abstract: A mobile sewage treatment and water reclamation system for rapid deployment to augment existing wastewater systems and provide interim service in lieu of permanent facilities, includes: (a) denaturing stage wherein raw sewage is first ground into suspendable grit, its pH first lowered to kill acid-sensitive bio-organisms, then raised to kill base-sensitive bio-organisms, and then neutralized; (b) clarifying stage employing an inverted-cone tank to circulate the solution after injection with chemicals to flocculate small particles for collection in a layer for siphoning off; and (c) disposal stage wherein clarified water passes through media filters to remove remaining solids and odors, the effluent water being clean enough for irrigation, aquatic life and discharge into waterways; and wherein sterile sludge is pressed into semi-dry solids, then dried, crushed, powdered and bagged for use as high-nitrate biomass fertilizer or for fossil-fuel power co-generation applications.

    Abstract: Method for removing hydrogen sulfide from fluids such as oil and gas well drilling, treatment, and production fluids and effluents from hydrocarbon operations and mineral mining operations. The sulfide scavenger used in the method is a gluconate salt other than ferrous gluconate. The gluconate salt is added to the fluid along with an iron source if iron is not already in the fluid. The gluconate reacts with the iron and forms iron gluconate in the fluid, which in turn reacts with the hydrogen sulfate to form iron sulfide which may be readily removed from the fluid.

Each gasification chamber may have a mechanism that ingests and mixes a second gas into the water thereby physically displacing at least a portion of the first gas into a vapor space at the top of each gasification chamber from which it is subsequently removed. There is an absence of communication between the vapor spaces of adjacent chambers.

    Abstract: A process for treatment of an aqueous stream to produce a low solute containing distillate stream and a high solute/solids containing blowdown stream utilizing a method to increase the efficiency of an evaporator while providing an essentially scale free environment for the heat transfer surface. Multi-valent ions and non-hydroxide alkalinity are removed from aqueous feed streams to very low levels and then the pH is increased preferably to about 9 or higher to increase the ionization of low ionizable constituents in the aqueous solution. In this manner, species such as silica and boron become highly ionized, and their solubility in the concentrated solution that is present in the evaporation equipment is significantly increased. The result of this is high allowable concentration factors and a corresponding increase in the recovery of high quality reusable water with essentially no scaling.

A facility for performing the method is also provided. The method includes removing the coarse solids from the mud, breaking the emulsion, separating the hydrophobic phase from the water phase and the solid phase, vaporizing all residual oil and water from the solids, and burning off the vaporized oil. The method produces a solid “soil” product that is free from oil contamination, an oil product that is fit for reuse, and clean air emissions. A thermal desorber can be used to efficiently vaporize the oil at low temperature. Optionally the water fraction of the mud can be vaporized, solutes and salts can be captured as evaporite and then be mixed with the soil product. The method has the unique advantage of producing no persistent hazardous waste.

  • Patent number: 7828979
    Abstract: A method for converting animal waste, in the form of waste slurry, to energy and useful byproducts. A screen mesh filters out large objects from waste slurry and the filtered slurry is chopped and fragmented to reduce binding of fibrous materials. The fragmented slurry is mixed at a rate to maintain solids in the fragmented slurry in suspension while minimizing aeration and turbulence within the mixing unit. A solids recovery unit recovers about 95% of the suspended solids. An additive is introduced into the solids recovery unit for providing agglomeration of solids particles. The recovered solids are gasified to produce at least methane/ethane gas. The produced gas is provided to an energy production unit to generate electrical and/or heat energy. Liquid remaining after the solids recovery is treated to remove undesirable contaminants to an extent in compliance with water quality standards set for animal waste flushing, animal washing and animal drinking water, as the case may be.

  • Patent number: 7815804
    Abstract: A method or process for treating wastewater containing high organics, silica, boron, hardness, and suspended and dissolved solids. The method includes degasifying the wastewater for the removal of dissolved gases and thereafter chemically softening the wastewater. After the chemical softening step, the wastewater is directed through a media filter or membrane which removes additional solids and precipitants. Thereafter the wastewater is directed through a sodium ion exchange that further softens the wastewater. The effluent from the ion exchange is directed through a cartridge filter and the effluent from the cartridge filter is directed through one or more reverse osmosis units. At a selected phase of the process, prior to the wastewater reaching the reverse osmosis unit or units, the pH of the wastewater is raised and maintained such that the pH of the wastewater reaching a reverse osmosis unit is at a pH greater than 10.5.

    Abstract: An emulsion treating unit and process. A subcooled boiling zone in the unit comprises a heat transfer surface to contact an emulsion at a temperature in excess of the saturation temperature of an aqueous phase in the emulsion, wherein the boiling zone is atmospherically vented. The unit also provides means for recovering an oil-rich layer from adjacent a vapor-liquid interface; and means for recovering an aqueous-rich layer from below the oil-rich layer. The process provides operation of the treating unit to heat an emulsion in the subcooled boiling zone, wherein the boiling zone is atmospherically vented, recovering an oil-rich layer and recovering an aqueous-rich layer from below the oil-rich layer. In one embodiment the boiling zone comprises a heat transfer surface having a temperature in excess of the saturation temperature of the aqueous-rich layer, wherein the vapor-liquid interface is subcooled with respect to the saturation temperature of the aqueous layer.

  • Patent number: 7681643
    Abstract: A process for conditioning of wastewater treatment brines for deep well injection during recovery of heavy hydrocarbon oils in situ. High pressure steam is used to mobilize oil, which is recovered in a mixture of oil and produced water. The produced water is pre-treated by removing residual oil. The remaining water is acidified and steam stripped to remove non-hydroxide alkalinity and non-condensable gases, and is then fed to a crystallizing evaporator, where it is evaporated from a circulating brine slurry to produce (1) a distillate stream having a trace amount of residual solutes, and (2) evaporator blowdown stream containing, as dissolved or suspended solids, substantially all of the solutes from the produced water feed. The distillate stream is used as boiler feedwater, either directly or after polishing. The evaporator blowdown is conditioned to remove substantially all suspended solids and to produce a clear brine solution for deep well injection.
