A waste oil handling apparatus features a tank with draining compartments for receiving waste oil containers in inverted and elevated positions above the tank floor. Multiple drain ports communicate with the tank interior at different elevations relative to the floor for draining accumulated contents of varying density that have gravitationally separated into distinct layers at those elevations. The ports feature adjustable fittings for adjusting the levels from which the layered contents are drawn through the ports from the tank interior. The tank has a large cleanout access by which personnel can access the tank interior for thorough cleanout. The compartments are organized into one or more troughs, each having a pivotal lid thereon. Lift brackets under the floor enable lifted transport of the tank by pallet jack or forklift.

Embodiments disclosed herein relate to an apparatus for refining a liquid stream which includes a liquid carrier with a heavier waste and a lighter waste. The apparatus includes a first flow chamber, a second flow chamber, and plates. The first flow chamber is a cone structure and directs the liquid stream downwards in a first direction at a first velocity. The first velocity is greater than a settling velocity of a heavier waste in the liquid carrier. The second flow chamber directs the liquid carrier upwards in a second direction at a second velocity less than the settling velocity. The plates are in the second flow chamber and at a transition between the first and second flow chambers. The plates have an inclined geometry to cause laminar flow in the liquid stream to separate the heavier waste to a lower collection chamber and lighter waste to an upper collection reservoir.

Embodiments disclosed herein relate to an apparatus for refining a liquid stream. The apparatus includes a first flow chamber, an inclined plate region, and a second flow chamber. The first flow chamber forms a first portion of an hourglass double cone structure and directs the liquid stream in a first direction at a first velocity. The inclined plate region includes inclined plates radiating outward from the hourglass double cone structure in a helical pattern. The inclined plate region directs the liquid carrier in a second direction opposite the first direction at a second velocity less than the first velocity forming a laminar flow condition in the liquid stream to separate heavy waste and light waste from the liquid stream. The second flow chamber forms a second portion of the hourglass double cone structure and directs the liquid stream to a liquid stream outlet.

Devices, systems, and methods for separating solids from liquids are disclosed. A vessel includes an inlet, a carrier liquid outlet, a product outlet, a purifying section, and a heater. The inlet directs a slurry into the purifying section. The slurry comprises particles of a solid and a carrier liquid. The purifying section preferentially drives the particles of the solid towards a heating zone of the purifying section versus the carrier liquid. This displaces a first portion of the carrier liquid away from the heating zone of the purifying section. The heater heats the slurry. The carrier liquid outlet drives a majority of the carrier liquid out of the vessel. The product outlet is adjacent to the heating zone of the purifying section.

A gas inlet system for a wet gas scrubber includes a weir configured to deliver liquid to a scrubbing passage to wet the interior surface of the scrubbing vessel during operation of the gas inlet system. The weir include a weir duct and a weir trough extending at least partially around the weir duct to receive and at least partially fill with liquid during operation of the gas inlet system. The weir trough has an upper trough outlet in liquid communication with the upper weir duct inlet to deliver liquid from the weir trough into the upper weir duct inlet during operation of the gas inlet system. The weir trough also has a lower trough outlet below the upper trough outlet. The lower trough outlet is in liquid communication with the scrubbing passage to deliver liquid from the weir trough toward the scrubbing passage during operation of the gas inlet system.

A method and system for treatment of flow-back and produced water from a hydrocarbon well in which fracturing operations are carried out using a phase separation and creating of positive charge in the water.

A well flow separator vessel having a sediment chamber at the inlet end of the vessel with a knock-down billet, followed by a coalescer and a first horizontal flow path between an upper horizontal divider and a lower horizontal divider extending the cylinder length from the sediment chamber towards the distal end of the vessel. At the far end of the first flow path, gasses are received through a scrubber/demister into a second horizontal flow path between the upper horizontal divider and the top side of the vessel, also extending the cylinder length, except directing flow in the reverse direction back towards the inlet end of the vessel towards a gas outlet. Also at the far end of the first flow path, combined liquids fall into a third horizontal flow path between the lower horizontal divider and the bottom side of the body extending the cylinder length towards the inlet end of the vessel, and having at a first one water separation chamber and one oil collection chamber separated by at least a first Weir plate, wherein the oil collection chamber terminates at the bulkhead. A plurality of outlets is provided for removing sediment, water and oil from the chambers and gas second horizontal flow path.

Embodiments of the present disclosure include systems and methods for collecting, storing, separating, and disposing of waste material from an oil and gas well site in order to enhance payload efficiency. An embodiment of a method, for example, may include introducing a waste material into an enhanced-payload mobile vessel positioned at the oil and gas well site, the waste material selected to include one or more of a sludge waste material, a solids-laden wastewater material, and a dry waste material. The method may further include transporting the waste material when positioned in the enhanced-payload mobile vessel along roadways to an off-site waste management facility. Additionally, the method may include dumping the waste material from the enhanced-payload mobile vessel by a site-based lifting mechanism into a receiving vessel at the off-site waste management facility thereby to dispose of the waste material at a reduced transportation cost.
