The present invention relates to a method for the separation of an oily mixture from an aqueous mixture and a kit for use in said method.

A degasification system includes a degasification unit in which a plurality of degasification modules degasifying a liquid are connected, wherein the degasification unit has a connection supply pipe which connects the liquid supply paths of the plurality of degasification modules in series and in which openings through which the liquid passes are formed at positions corresponding to the plurality of degasification modules such that the liquid is supplied to the hollow fiber membrane bundles of the plurality of degasification modules in parallel, and wherein the degasification unit is configured such that a pressure loss of the liquid from a supply port of the connection supply pipe through which the liquid is supplied to the discharge ports of a downstream side degasification module is larger than a pressure loss of the liquid from the supply port to the discharge ports of an upstream side degasification module.

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 flow back system for separating solids from a slurry recovered from a hydrocarbon well. The system includes a V-shaped tank with a first series of baffles configured to cause the settling of solids that are moved by a shaftless auger to a conduit fluidly connected to hydrocyclones mounted over a linear shaker. The overflow from the hydrocyclones is discharged through a second conduit back into the tank for processing by a second series of baffles resulting in a clean effluent. The clean effluent is recirculated in the well.

A monolithic membrane-type filtration structure for filtering liquids, includes a support formed of a porous inorganic material of permeability K.sub.s, the support having a tubular overall shape with a main axis, an upstream base, a downstream base, a peripheral wall delimiting an internal part and a plurality of passages parallel to the main axis of the support, formed in the internal part of the support, a membrane of permeability K.sub.m and of mean thickness t.sub.m covering the internal surface of the passages; the external hydraulic diameter of the structure satisfying the relationship Ø.sub.f=α×[A+B×log.sub.10 (K.sub.s×t.sub.m/K.sub.m)]; in which α is a coefficient between 0.85 and 1.15, and A=−21570×ent.sub.int.sup.2−18.6×D.sub.h+19.0×e.sub.int−2.5×e.sub.ext+0.1244 B=−11760×D.sub.h×e.sub.int+9.7×e.sub.int+3.1×e.sub.ext+0.04517. D.sub.h is the mean hydraulic diameter of the passages, e.sub.int is the minimum thickness of the internal walls between the passages, e.sub.ext is the minimum thickness of the peripheral wall of the filter.

A separation apparatus for separating constituents from effluent. The separation apparatus includes a gas diffuser, a hopper, and a tank. The gas diffuser includes an inlet inner tube for receiving effluent from a well. The hopper is disposed at least partially below the gas diffuser, and the tank is connected to the hopper. The gas diffuser is configured so that gas in the effluent is released from the effluent and into the atmosphere before the effluent enters the hopper. The hopper is configured so that liquid effluent in the hopper spills over a top portion of the hopper and into the tank.

A vertical dryer system and method for managing oil well solids and liquids includes a vertical dryer; a hopper for well drilling cuttings mixed with residual liquids; and an enclosed drag chain conveyor having an opening into the hopper for picking up drill cuttings and associated liquids. The enclosed drag chain conveyor extends from the hopper to a vertical dryer, there being an opening in said enclosed drag chain located at said vertical dryer, whereby drilling cuttings and associated fluids being conveyed by said drag chain are delivered to said vertical dryer for drying. The enclosed drag chain conveyor returns again to said hopper in a continuous enclosed loop except for the openings.

The present disclosure is directed to providing an oil-water separation filter structure including a base guide having a separated water outlet hole through which a fluid separated from a mixed fluid including an impurity exits, an oil-water separation filter disposed on the base guide to separate the impurity and the fluid included in the mixed liquid, and a top guide disposed on the oil-water separation filter, having at least one mixed fluid inlet hole through which the mixed fluid enters, and coupled to the base guide. According to the present disclosure, the oil-water separation filter structure includes a hydrophilic material to separate water and oil, and as opposed to the existing nonwoven fabric type filters, can be continuously used, thereby preventing environmental pollution problems.

A process and device to create access to low gravity solids (LGS) of about 2 to 20 microns for removal from a fluid material/LGS emulsion having the steps of: flowing the emulsion into high pressure tubing; separating the emulsion into at least two high pressure streams; forcing the emulsion through high pressure nozzles at a terminus of each of the at least two high pressure tubing streams at a speed in the range of about 10 ft/sec to 200 ft/sec or at a force in a range of about 10 to 100 PSI; and colliding the streams of emulsion exiting the high pressure nozzle within a pressure drop chamber, wherein the pressure drop is in a range of about 5% to 50% of the back pressure of the nozzles; wherein a cavitation effect is realized from a collision force of the high pressure streams within the pressure drop chamber.

A sand separator for capturing solid debris from oil and gas wells includes a spherical, high-pressure vessel adapted to couple downstream of a wellhead. Fluid entering the separator follows a helical path around a vertical separator axis, slowing and separating into water, gas, oil and solid debris, the latter sinking to the bottom. A conical, downwardly opening flue descends from an exit port at the top and terminates in a horizontal, coaxial perimeter. A scalloped, annular collar inside the flue perimeter creates a low barrier to fluid flow into the flue. As fluid constituents circulate toward the flue, they recombine free of sand and rock debris, pass under the flue perimeter and across the collar, slowing further and becoming substantially laminar A fluid dome rises inside the flue with a gas layer above other fluid constituents, permitting the gas to exit the separator through the exit port.
