A gas separator, gas separation system, and method for separating gas from drilling cuttings by actively maintaining a liquid seal of liquid in a lower portion of a separation vessel by controlling an introduced amount of the liquid admitted to the separation vessel as a removed amount of the liquid is removed from the separation vessel and by promoting agitation of the drilling cuttings in the liquid in an agitation chamber within the lower portion of the separation vessel to aid removal of the drilling cuttings along with the removed amount of the liquid.

A main housing provides a first reservoir and a second reservoir. Water flows from the first reservoir to the second reservoir. A draining aperture in the first reservoir directs water from the first reservoir to the second reservoir. The water may be flushed from the first reservoir to the second reservoir. In another embodiment, the water may flow directly from the first tank to the second tank without the flush. A pump circulates water from the second reservoir to the first reservoir. The pump directs the water through a filtration system to filter the water to remove at least some of the dirt, debris, and other contaminants from the water. The filtered water is then returned to the first reservoir. An overflow relief in a dividing wall of the first reservoir directs overflow water to the second reservoir.

A transportable multi-chamber water filtration system useable at construction sites with sources of contaminated water is disclosed. The transportable multi-chamber water filtration system removes sediment and contaminants from contaminated water by combined processes of gravitational settling, filtration and coagulation of sediment by the use of flocculants. The system provides efficient removal of sediment and contaminants from the water around various sized sites.

A mechanical separator for separating a fluid sample into first and second phases within a collection container is disclosed. The mechanical separator may have a separator body having a through-hole defined therein, with the through-hole adapted for allowing fluid to pass therethrough. The separator body includes a float, having a first density, and a ballast, having a second density greater than the first density. A portion of the float is connected to a portion of the ballast. Optionally, the float may include a first extended tab adjacent a first opening of the through-hole and a second extended tab adjacent the second opening of the through-hole. In certain configurations, the separator body also includes an extended tab band disposed about an outer surface of the float. The separator body may also include an engagement band circumferentially disposed about at least a portion of the separator body.

A negative pressure shale shaker integrated with negative pressure generation and gas-liquid separation includes a base, a liquid inlet buffer tank, a screen frame assembly, a support frame, a vacuum hose, a damping spring, a screen frame inclination angle adjustment device, a drainage hose, a negative pressure automatic drainage device, a vacuum pan, a three-way pipe, a liquid mist separator, a connecting pipe, a vacuum pressure limiting valve, a silencer and a negative pressure fan. A drilling fluid containing cuttings, after entering the screen with a negative pressure thereunder, rapidly passes through the screen along with air into a vacuum chamber. The air in the vacuum chamber is directly drawn away through holes formed on the side plates of the screen frame by the negative pressure fan.

Methods and systems are provided for operating a vehicle including an engine and a fuel system. In one embodiment, a water drainage system for a fuel system comprises a fuel tank, a fuel-water separator in fluid communication with the fuel tank, and a purge tank in fluid communication with the fuel-water separator and the fuel tank, the purge tank separate from the fuel tank. The water drainage system further includes a fuel property sensor for detecting a presence of water and a purge line in fluid communication with the purge tank for removing fluid from the purge tank, a flow of the fluid from the purge tank controlled by a check valve.

A method for removing solids submerged in a polymer-based slurry. The present invention filters used polymer-based slurries, containing solids, to return the slurry to a condition that is favorable to the owner. The method utilizes a first collection tank, an agitator, a shaker with a plurality of screens, a desander, a desilter, a centrifuge that removes solids down to a size range of 5-7 microns, and a second collection tank. Each component can be used in tandem depending on the polymer-based slurry characteristics that are required by the owner. The preferred embodiment includes the following steps: obtaining used polymer-based slurry, pumping the slurry into a first collection tank where the slurry undergoes agitation, pumping the slurry through a plurality of screens, pumping the slurry into a desander and/or a desilter, passing the slurry through a screen, and pumping the slurry in centrifuge that removes solids down to a size range of 5-7 microns. After completion of the method, the owner can decide to repeat the steps to obtain a polymer-based slurry in accordance with their requirements.

The present invention relates to a tubular oil separator providing separation of respective fluid components mixed in fluids from oil wells, wherein the tubular oil separator A is arranged to mitigate problems related to turbulence and possible non-Newtonian fluid behaviors of fluid components mixed in the fluids from the oil wells in the oil separator. The invention further relates to a method of operating a separator. Moreover the invention relates to a system of multiple separators. Inventive aspects of the separator comprises an elongated outer, closed tubular section and an elongated, inner tubular section, which is closed in one end and open in another end, —where the inner tubular section is arranged inside the outer tubular section, —and where oil well substances are introduced into the open end of the inner tubular section via a tube feed section passing through the outer tubular section and into the inner tubular section, —and where the inner tubular section comprises multiple, elongated and parallel slots arranged in a longitudinal direction of the inner tubular section in a circumferential manner, —where the inclination of the separator facilitates separation of the oil well substances into lower density substances and higher density substances, —where the lower density substances by buoyancy drift upward through the slots and exit via an upper outlet in the outer tubular section and higher density substances sink downward through the slots and by gravitation exit via a lower outlet in the outer tubular section.

In a method for fabricating a separation fence (1) to be used in a hydrometallurgical liquid-liquid solvent extraction settler, the fence is manufactured of polymer resin. The fence (1) is manufactured as a shell-like integral piece by rotational molding. The fence (1) is a rotationally molded shell-like integral piece.

An inlet arrangement for a tray-based grit removal system utilizes a set of separate inlet hoses to connect the vertical stack of trays to a horizontally-disposed inlet chute, thus eliminating the inlet duct utilized in prior art configurations. Each hose is configured to have about the same length and diameter, providing an essentially uniform influent pressure at the input to each tray. The hoses are directly connected between the trays and the inlet chute, where each tray may be formed to include a hose coupler of the same diameter as the hose. The inlet chute may take the form of a trough or tube (or other suitable geometry), with the plurality of hoses all terminating along a common, horizontal output face of the chute.
