A recovery system for large-scale spilled oil flowing onto and adhered to a shore is disclosed. The recovery system for large-scale oil flowing onto and adhered to a shore is mounted on an amphibious vehicle that can move on a neritic zone and land. A skimmer assembly is installed in a front of the amphibious vehicle. An oil collection assembly is foldably provided on each of front opposite sides of the amphibious vehicle, thereby easily collecting oil. A recovered oil treatment assembly is mounted on the amphibious vehicle and configured to accommodate the oil recovered by the skimmer assembly therein and to store separated oil by separating water from the accommodated oil.

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.

Removable trap stations for hydrocarbon flowlines can be implemented as an apparatus. The apparatus includes a multi-phase fluid receiver body and a tank defining an interior volume. The fluid receiver body is configured to couple to a flowline carrying a multi-phase fluid including solids and liquids. The fluid receiver body includes an inlet portion configured to receive a portion of the multi-phase fluid including a portion of the solids flowing through the flowline into the receiver body. The fluid receiver body includes an outlet portion fluidically coupled to the inlet portion. The portion of the multi-phase fluid is configured to flow from the inlet portion to the outlet portion. The tank is fluidically and detachably coupled to the outlet and is configured to receive and retain the portion of the multi-phase fluid received through the inlet portion.

Vaults, boxes, systems, and methods of treatment systems to capture pollutants from storm water runoff and prevent the conveyance of these pollutants from entering a receiving water body or landscape area, which is designed to be a part of a local permanent storm water drainage infrastructure. A single treatment box, vault and system combines both drainage conveyance, multi-level treatment techniques, variable hydraulic capabilities, and easy and inexpensive methods for servicing the system, along with a hinged skimmer system with or without a float. The hinged skimmer system can include a rigid vertical panel attached by pivotal support rods that allow the vertical panel to move up and down along a vertical plane in front of an outlet flow line to a vault. The system can also include components selected from a shelf or baffle beneath the hinged skimmer, a dual screened filtration system, media filtration, and hydroslide water pressure lines with spray heads for cleaning debris on a sloped floor, as well as a flow spreader, debris ramp and screened deflector.

An apparatus for, and a method of, separating oil, water, gas and solid particles (usually sand) from a hydrocarbon-containing fluid produced from an oil and/or gas production facility. In particular, this invention relates to an apparatus and method for the separation of oil, water, gas and solid particles from a well or group of wells using an integrated apparatus which significantly reduces the space required on the production platform or rig and recycles produced gas to improve process efficiency while reducing cost.

A system for separating solids from a fluid includes a containment vessel having a V-shaped tank in fluid communication with an agitated overflow tank. Baffles within the V-shaped tank provide a series of zones where the fluid is deposited for processing. A shaftless auger at the bottom of the V-shaped tank transfers solids to an area where they are pumped to a first hydrocyclone assembly associated with a first shaker. Overflow from the hydrocyclone assembly and underflow from the first shaker is further processed by a second hydrocyclone assembly associated with a second shaker. Overflow from the second hydrocyclone assembly and underflow from the second shaker are deposited into overflow tank which contains the cleaned fluid.

The present invention provides a multiphase separator for separating a multiphase fluid produced by one or more oil wells, the multiphase separator comprising: a separating vessel, comprising an inlet chamber and an oil chamber for collecting oil at least partially separated by a barrier; an inlet for introducing the multiphase fluid into the separating vessel; wherein the oil chamber is positioned on the opposite side of the barrier to the inlet; a gas outlet configured to collect gas separated from the multiphase fluid; an oil outlet configured to collect oil, separated from the multiphase fluid, from the oil chamber; a water outlet configured to collect water separated from the multiphase fluid; and a gas and water mixture injector configured to inject a mixture of pressurized gas and water in a lower portion of the separating vessel.

The invention relates to a method for clarification of raw green liquor in a sedimentation tank. According to the invention is a part of dregs separated in the sedimentation tank recirculated back into the inflow of raw green liquor, and preferably after passing the dregs through at least one turbulence generator (30, 31) that could break up larger dregs particles into smaller dregs particles, and thus create larger total surface on the dregs particles, improving sedimentation rate in the sedimentation tank. In a preferred embodiment is the recirculated dregs added into the flow of raw green liquor before a flocculant is added into the flow of raw green liquor and mixed recirculated dregs.

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.

Systems, devices, and methods for providing nutrient removals in an up flow filtration storm water system for treating water to very high clean levels using filtration media. A filtration media can be supported by a screen above a floor in a vault allows for incoming storm water to pass into a void space above the floor into the screen and filtration media and then out an outlet to the vault. The filtration media can include recyclable and/or natural particles. Layers of river rocks can be placed on top of and below the filtration media. The captured debris can drop to the floor. The long lasting filtration media can be cleaned by being backwashed.
