A well production particulate measurement system having a stationary frame removably mountable to tank, a hopper coupled to the frame and moveable relative to the frame; a well production inlet configured to receive well production and discharge the particulates and liquid into the hopper, and to strip at least a portion of a gas phase from the well production; and a weight transducer coupled to the system and configured to sense a weight of particulates in the hopper.

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.

A slurry removal system includes a tank, an eddy pump, and a pipe system. The tank is configured to receive a mixture of solid material and liquid. The eddy pump has a pump inlet connected to the tank and a pump outlet. The pipe system is connected to the pump outlet and including a discharge line and a recirculation line. The eddy pump is configured to pump the mixture of solid material and liquid from the tank through the pump inlet to the recirculation line to form an essentially homogeneous mixture, and configured to pump the essentially homogeneous mixture from the tank through the pump inlet to the discharge line to remove the homogeneous mixture from the tank.

A system for treating wastewater comprising a coagulation-flocculation assembly having a raw wastewater inlet and a coagulated-flocculated wastewater outlet; and a slurry separator comprising an intake area configured for receiving wastewater slurry from the coagulated-flocculated wastewater outlet, a liquid outlet, a sludge outlet, and a filtration module configured to facilitate percolating of liquid therethrough and forming of a filter cake thereon. The slurry separator being configured to receive slurry at the intake area, separate the slurry to liquid and sludge by the filtration module, remove the liquid via the liquid outlet, and convey the sludge from the intake area to the sludge outlet. The system further comprises a level maintaining arrangement configured to maintain at least a minimal level of the filter cake.

A sand handling system having, for example, one to three sand separators are configured to be operatively connected to a well and an inlet of a common dumping vessel. Advantageously, the dumping vessel has a sensor to measure an amount of sand in the dumping vessel and provide a signal to a programmable controller which is arranged to dump the dumping vessel when a specified amount of sand is in the dumping vessel. The system automates the sand handling process and also measures and records data associated with a number of flowback parameters. The data can then be used in well design to improve oil and/or gas production, lessen sand production, reduce well damage and/or equipment corrosion due to, for example, sand.

A separation device and method for treating effluent mixture streams including one or more liquid component(s). The device and method can utilize gravity and/or hydromechanical separation to separate non-water components from the effluent mixture. The device and method more particularly relates to an improved large capacity grease interceptor having an integrally formed double baffle sidewall within the tank reservoir to control the movement of effluent mixture within the reservoir, as well as significantly improve structural integrity of the device and ease of manufacturing and assembly.
