Provided is a liquid processing apparatus and a liquid processing method for reducing a waste amount of a high specific gravity liquid. The liquid processing apparatus includes: a supply pump; a bubble tank including an inflow port, an overflow port, and a return port; a microbubble generator disposed outside the bubble tank; a recovery tank having a recovery port to recover the processing liquid overflown from a first liquid level to the tank; a separation tank including a settling tank connected to the overflow port, and a floating tank connected to the settling tank at a lower portion, and an ejector having a inlet port connected to the supply pump, a suction port connected the suction body, and a discharge port connected to the return port.

The present techniques are directed to a multiphase separation system. The system includes a liquid-liquid separator configured to receive a separated liquid that is further separated into a separated oil and a separated water within the liquid-liquid separator. An oil pump and a water pump, both with adjustable speeds, are configured to pump the separated oil and the separated water, respectively, from the liquid-liquid separator. An interface level in the liquid-liquid separator is regulated by adjusting the speed of the oil pump and the speed of the water pump.

A saturated layer stormwater filtering system with down-flow layered multimedia filters is disclosed. The filtering system may include an upflow pretreatment chamber and a subsequent filtration chamber. It also includes a snorkel pipe as an adjustable head control or internal baffles. The system incorporates gravity powered partially saturated stormwater media filters to harness the potential energy of stormwater from downspouts and pumped flows from stormwater catchments to drive the polluted stormwater in a hydraulically controlled fashion by gravity through a series of filter media layers.

A neutralization/water separation device for an esterified product including: a neutralization tank in which a crude product mixture containing alcohol and an ester compound, a neutralizing agent, and water are put to produce a neutralized mixture; a water separation tank disposed below the neutralization tank to divide the neutralization mixture into a floating layer and an aqueous layer; a partition wall extending downward from a ceiling of the water separation tank to provide a lower passage in the water separation tank; and a transfer line that transfers the neutralized mixture from the neutralization tank to the water separation tank, where the water separation tank includes: a first water separation part into which the neutralized mixture is introduced from the neutralization tank through the transfer line; and a second water separation part into which the neutralized mixture is introduced from the first water separation part through the lower passage, where the first water separation part and the second water separation part are partitioned by the partition wall.

A method of treating oil and gas produced water may include: receiving produced water from one or more wells; separating an aqueous portion of the produced water from oil and solids included in the produced water in order to provide recovered water; performing anaerobic bio-digestion of organic matter included in the produced water using a biomass mixture of anaerobic bacteria obtained from a plurality of wells; aerating the recovered water in order to promote metal precipitation; and performing aerobic bio-digestion of organic matter present in the recovered water. Some embodiments may also include one or more of anoxic equalization, filtration, pasteurization, reverse osmosis, and biocide treatment of the recovered water. The recovered water may be used for oil and gas well fracking and/or land and stream application. Other methods of treating oil and gas produced water are also described.

A system and method for processing unconditioned syngas first removes solids and semi-volatile organic compounds (SVOC), then removes volatile organic compounds (VOC), and then removes at least one sulfur containing compound from the syngas. Additional processing may be performed depending on such factors as the source of syngas being processed, the products, byproducts and intermediate products desired to be formed, captured or recycled and environmental considerations.

A grease trap is provided. The grease trap comprises a container having an inlet opening and an outlet opening disposed in an upper portion thereof and a liner placed inside the container. The liner forms an enclosure and comprises a liner body having an inlet fitting and an outlet fitting mounted thereto. Each of the inlet fitting and the outlet fitting protrude the respective inlet opening and outlet opening and each of the inlet fitting and the outlet fitting are adapted for being connected to a plumbing system for receiving water containing FOG and for providing the water after separation of the FOG, respectively. An inlet baffle and an outlet baffle are disposed inside the liner body and mounted thereto. The inlet baffle and the outlet baffle each surround a respective inlet and outlet and extend downwardly therefrom.

A crude oil desalter unit includes a settler, an inlet manifold fluidly coupled to the settler, and one or more inlet distributors extending from the inlet manifold to discharge a water-in-oil emulsion into the settler. Each inlet distributor includes a riser having a first end, a second end, and an inner flowpath extending between the first and second ends, wherein the riser is coupled to the inlet manifold at the first end, one or more outlet nozzles provided at the second end and in fluid communication with the inner flowpath, and a static mixer positioned within the inner flowpath and defining one or more helical pathways operable to induce rotational flow to a fluid flowing within the inner flowpath.

A system and method for processing unconditioned syngas first removes solids and semi-volatile organic compounds (SVOC), then removes volatile organic compounds (VOC), and then removes at least one sulfur containing compound from the syngas. Additional processing may be performed depending on such factors as the source of syngas being processed, the products, byproducts and intermediate products desired to be formed, captured or recycled and environmental considerations.

Efficient and economical systems and processes described strive to minimize the amount of NGLs and gas purchased, by recycling and reusing the gas and NGLs from producing wells on site for enhanced oil recovery. The EOR fluid is maintained in the liquid phase, greatly reducing the cost and energy consumption of the EOR injection equipment needed. The processes and systems described avoid or significantly decrease the need to purchase NGLs and truck them to the site for EOR, avoid large amounts of compression work, and use refrigeration equipment as an option for improved equipment performance only when desired. Systems and processes use a one-step approach to separate and stabilize the crude from the produced water, the NGLs and the natural gas, reducing the complexity associated with oil production surface infrastructure and eliminating the vast majority of the fugitive emissions associated with current state-of-the-art oil production.
