The present invention relates to intelligent oil sludge treatment apparatuses and treatment processes. The treatment apparatus includes an integrative device, an oil removal device, a separation device, a sludge collection tank, a dewatering device, a pyrolysis device, an agent tank, a deodorization tower, a crude oil tank, a light oil tank, a separator, a condenser, a desulfurization tower, a clean water tank, a sewage station, and a steam boiler, where an outlet of the integrative device is connected to an inlet of the oil removal device; the oil removal device is configured to remove crude oil from oil slurry; the oil removal machine collects the crude oil to the crude oil tank, discharges stench into the deodorization tower, and discharges the slurry into the separation device; and the separation device is configured to perform a solid-liquid separation operation.

A permeable membrane tube to separate mixed fluids is provided, including a cyclone generator configured to cause fluid entering the permeable tube to flow in a spiral direction. The cyclonic generator may be a plug positioned at the fluid entrance of the membrane tube. The fluid passes through the permeable membrane tube, which has a center axis along a length of the tube, and flows in the spiral direction thereby separating the fluid into first and second portions, wherein the first portion comprises fluid having a greater density than the second portion and the first portion is directed to an inner surface of the tube.

Described is a method for concentration and extraction of gas field chemicals. The method includes collecting produced water from a gas oil separation plant, treating the produced water to remove oil, and receiving a feed solution containing a gas field chemical and water. The treated produced water is used as a draw solution to concentrate and absorb water from the feed solution using a forward osmosis chamber. A concentrated feed solution containing the gas field chemical and a diluted draw solution is produced. The concentrated feed solution is extracted and stored for injection into gas wells.

Systems and processes for water-oil separations include feeding an oil-water mixture to an inlet of a water-oil separation vessel for separation of the decontaminated water from the oil. Steam bubbles are used to facilitate the separations, where the systems and processes include a water circulation loop for circulating a portion of the decontaminated water through the water circulation loop and heating the water to generate steam via solar energy captured by the concentrated solar collector. The steam may then be fed to a distributor in a separation chamber of the water-oil separation vessel, the distributor distributing the steam in the separation chamber of the water-oil separation vessel as a plurality of bubbles, facilitating separation of oil from water.

A process for separation of a slurry by radially injecting a stream of a nanogas solution at a shear-focus volume within a pipe; passing an aqueous slurry through the pipe along a direction of flow and through the shear-focus volume; and shearing and/or admixing the slurry with the nanogas solution within the shear-focus volume.

The present invention relates to a method for removing hydrocarbons from produced water, comprising: (i) separating produced water from a hydrocarbon and water mixture extracted from a subterranean formation: (ii) contacting said produced water with multivalent metal cations to produce a mixture of produced water and multivalent metal cations; and (iii) removing hydrocarbons from said mixture in a hydrocyclone and/or a compact flotation unit to give treated produced water, wherein the concentration of hydrocarbons in said produced water is less than 10% wt.

Apparatuses to remove entrapped air and debris from bitumen are provided. The apparatuses include a tank comprising a first and second compartment with a separating surface therebetween. Bitumen froth can be received in the first compartment and can flow from the first compartment to the second compartment via the separating surface along a first portion of the flow path. The debris is separated from the bitumen in the first compartment and eliminated through a disposal aperture to form intermediate bitumen. The intermediate bitumen then travels along a second portion of the flow path to the second compartment where it is heated to allow entrapped air to escape and form processed bitumen, prior to exiting from the apparatus. The apparatus is particularly suitable for removing entrapped air and debris from bitumen mined from bituminous sands. Related processes for operating the apparatuses are also provided.

A solvent-removing apparatus according to an embodiment includes a tank body accommodating an emulsion including first source material in a continuous phase and second source material in a dispersed phase, a fluid supply unit for supplying fluid into the tank body to cause the emulsion to circulate, and a discharge unit for discharging the gas in the tank body to the outside.

A system for sand cleaning including: a cleaning unit arranged to receive oil impregnated sand; the unit including a chamber having an impeller, said impeller arranged to agitate the oil impregnated sand in a base of the unit; an aperture in the base of the unit arranged to discharge the treated sand; an oil outlet adjacent to a top of the unit arranged to discharge the separated oil.
