The universal separator is a device that provides simultaneous separation of solids and oils (and potentially gases) from water. It has applications in many industries including: Sewage Treatment; Water Treatment; Oil & Gas (tailings ponds, SAGD, etc.); Mining; and Food Processing. Furthermore, the concept offers virtually endless operating and geometric variations depending on the application. The universal separator employs various means of separation including coagulation, cyclonic separation, recycling, electrostatic demulsification and oil floatation.

A sand bypass separator is provided for separating particulate matter from a fluid mixture in a production well and directing the separated particulate matter away from a pump intake. The separator includes an outer tube, an inner tube positioned within the outer tube. The outer tube has a plurality of slots to allow the fluid mixture to enter the separator between the outer tube and the inner tube. As the fluid mixture moves downward, the fluid mixture reaches a downward velocity sufficient to allow the particulate matter in the fluid mixture to continue downward as the fluid is drawn into the inner tube through the pump intake. A bypass that extends from above the pump intake to below the pump intake to collect and direct the separated particulate matter separated below the pump intake may also be included.

A system for separating a multiphase well stream into a solids fraction, a water fraction, an oil fraction and a gas fraction includes a transportable support surface; a solids separator which is mounted on the support surface and is configured to receive the multiphase well stream and separate the well stream into a first heavy fraction primarily comprising the solids fraction and a first light fraction primarily comprising the gas, oil and water fractions; and a multiphase fluid separator which is mounted on the support surface and includes a first separator section and a second separator section which is positioned vertically below and connected directly to the first separator section. The first separator section is configured to receive the first light fraction and separate the first light fraction into a second light fraction primarily comprising the gas fraction and a second heavy fraction primarily comprising the oil and water fractions. The second separator section is configured to receive the second heavy fraction and separate the second heavy fraction into a third light fraction primarily comprising the oil fraction and a third heavy fraction primarily comprising the oil fraction.

A drilling fluid processing system for processing drilling fluid to remove solids and hydrocarbons from the drilling fluid at a drill site includes a transportable skid upon which equipment of the system is mounted and is transportable together as a unit. Equipment mounted to the skid include separator tanks, settling tanks, pumps, heating system, polymer injection system, vacuum system, and centrifugal separators. The system further includes a centrifugal separator support platform that is movable between a raised, operation position and a lowered, transport position. Additionally, the system is easily configured to operating in several different process operation modes according to a desired drilling fluid treatment.

Column for carrying out mass exchange processes, in particular desorption and absorption processes, said column comprising: a vertical cylindrical container comprising a first cylindrical container section having a first height hi and a first diameter d1, a second cylindrical container section having a second height h2 and a second diameter d2, a third cylindrical container section having a third height h3 and a third diameter d3 and a fourth cylindrical container section having a fourth height h4 and a fourth diameter d4 from bottom to top in a longitudinal direction of the container, a gas, in particular air, inlet in the wall of the first container section and a liquid outlet in the first container section, a polyethylene packing in each of the second container section and the third container section, a liquid inlet in the wall of the third container section, a liquid distributor that is placed in the third container section and is in fluid connection with the liquid inlet, and a gas mixture, in particular air mixture, outlet in the fourth container section, mass exchange apparatus comprising such a column, method for extracting iodine from drilling and/or formation water of oil or gas fields by air and use of such a column or mass exchange apparatus for extracting iodine from drilling and/or formation water of oil or gas fields by air.

A process for removing volatile diluent(s) from processed solids, generated from unstabilized drilling waste being washed in a diluent/solvent wash process. The process describes the use of hot water to deliver quality heat energy to the processed solids phase, evaporating the diluent and at least partially removing chlorides or other soluble or insoluble contaminants in the process, resulting in enhanced efficiency of diluent and contaminant recovery, for example, as a result of the near infinite surface area of water, among other things.

A separator system and method may provide a four-way separator that may separate a material and remove a hazardous material. The hazardous material may include gas and sand that may be removed by the four-way separator. The separator system and method may further provide a main unit that may include three chambers or recirculation hoppers, an auger sand extractor, and a strap tank. The separator system and method may provide a faster rig-up time and may be exclusively driven by hydraulics.

A sand bypass separator is provided for separating particulate matter from a fluid mixture in a production well and directing the separated particulate matter away from a pump intake. The separator includes an outer tube, an inner tube positioned within the outer tube, and a bypass. The outer tube has a plurality of slots to allow the fluid mixture to enter the separator between the outer tube and the inner tube. As the fluid mixture moves downward, the fluid mixture reaches a downward velocity sufficient to allow the particulate matter in the fluid mixture to continue downward as the fluid is drawn into the inner tube through the pump intake. The bypass extends from above the pump intake to below the pump intake to collect and direct the separated particulate matter separated below the pump intake.

Oil-gas separators and methods of using the oil-gas separators are disclosed. An exemplary oil-gas separator comprises a first fluid channel for receiving a well fluid, the first fluid channel having an open proximal end, a sealed distal end, and a plurality of perforations in a distal portion of the first fluid channel's exterior wall for expelling well fluid comprising oil and entrained gas into an annular space between the oil-gas separator and a well casing to produce gas-reduced oil and a second fluid channel for receiving the gas-reduced oil, the second fluid channel having a sealed proximal end, an open distal end for expelling the gas-reduced oil to the Earth's surface, and a plurality of perforations in a proximal portion of the second fluid channel's exterior wall for receiving fluid from the annular space.

A tank system may be conventional and fixed, or mobile, such as a fracking fluid or other tank trailer. A drain port thereof is fitted with an adapter connecting a snorkel system to drain liquids from near the top of the liquid level in the tank. A snorkel head at the extreme distal end of a tube near the longitudinal center of the tank is suspended by a system of buoys. A flow field controller resists formation of vortices near the snorkel head, so it can operate as near the surface as possible, withdrawing the highest grade oil efficiently without entrainment of overlying gases and vapors, nor the second liquid layered therebelow. All are configured to fit into the tank without requiring any personnel to enter the tank. Oil, water, and sludge may drain through the system to exit the tank.
