A mud cleaning system may include a system inlet carrying mud from a wellbore, a heater, a fluid separating system, and a system outlet carrying the mud to a holding vessel. The system inlet, the heater, the separator, and the system outlet may be fluidly connected such that mud flows from the system inlet, into the heater and the separator, and then out the system outlet.

A separation apparatus for separating constituents from effluent. The separation apparatus includes a gas diffuser, a hopper, and a tank. The gas diffuser includes an inlet inner tube for receiving effluent from a well. The hopper is disposed at least partially below the gas diffuser, and the tank is connected to the hopper. The gas diffuser is configured so that gas in the effluent is released from the effluent and into the atmosphere before the effluent enters the hopper. The hopper is configured so that liquid effluent in the hopper spills over a top portion of the hopper and into the tank.

An oleophilic separation apparatus has a rotatable metal cage and at least one oleophilic sieve in frictional engagement with the rotatable metal cage. The oleophilic sieve is made of an oleophilic material such that a bitumen phase adheres to the oleophilic sieve upon contact. A plurality of apertures in the oleophilic sieve allows aqueous phase to escape from the rotatable metal cage. A hot zone is provided that has at least one rotation member and a source of heat. The oleophilic sieve is in frictional engagement with the at least one rotation member. The hot zone heats the bitumen phase adhered to the oleophilic sieve to allow for collection of the bitumen phase.

A filtration and testing device integral thereon, for simultaneously performing cleaning of fluid used in the oil and natural gas industry for completions, workovers, and commissioning of wells while simultaneously pressure testing of two separate groups of pressurized equipment using fluid cleaned by the filtration and testing device. A support structure has a cleaning cycle assembly and a pressure testing cycle assembly connected in parallel to a controller for cleaning fluid and regulating pressure by comparing fluid pressures to preset limits. The controller regulates cleaning of first and second dirty hydraulic fluids and regulates pressure of cleaned hydraulic fluids and secondary fluids for pressure testing of the two different groups of pressurized equipment simultaneously.

A diffuser and solids collection system includes a first baffle section having an input for receiving from a petroleum well a fluid carrying solids and a first set of internal baffles for reducing a velocity of the fluid. A second baffle section in fluid communication with the first baffle section has a second set of internal baffles for further reducing the velocity of the fluid. A solids collection container separates the solids from the fluid received from the second baffle section. A weighing system, supported by the second baffle section and supporting the solids collection container, weighs the solids collected in the solids collection container.

A dynamic demulsification system to facilitate the removal of water from oil for use in a gas-oil separation plant (GOSP) which has a dehydrator vessel in fluid communication with a desalter vessel which in turn is in fluid communication with a water/oil separator vessel includes the following system components: an in-line microwave treatment subsystem upstream of one or two of each of the dehydrator vessel, the desalter vessel and the water/oil separator vessel, each of which vessels receives a water-oil emulsion; a sensor for the real-time monitoring and transmission of data representing one or more properties of the water-oil emulsion in the respective vessel(s) and/or downstream of the respective vessel(s) with which the sensor is associated; and a processor/controller that receives the data from the sensor and transmits one or more signals to the one or both of the respective in-line microwave treatment subsystem(s) to generate and apply microwave energy of predetermined characteristics to the flowing fluid based on the properties of the emulsion.

A desanding wellhead includes a wellhead device in communication with a well and configured to receive a mixed fluid produced therefrom, and a sand separation device coupled to the wellhead device. The sand separation device is configured to receive fluid from the well via the wellhead device, separate at least some solids from the fluid, and provide at least some of the fluid back to the wellhead device.

Stacked-plate filters may include a plurality of stacked filter plates with small gaps therebetween. The present disclosure provides a stacked-plate filter apparatus comprising a plurality of filter plates stacked along a longitudinal axis with the filter plates substantially parallel. Each filter plate has a respective outer rim, first face and second face. Each of the filter plates defines a respective opening therethrough. The outer rim forms a first peripheral edge at the first face and a second peripheral edge at the second face. The first peripheral edge is radially misaligned from the second peripheral edge to form an offset gap interface for each adjacent pair of the filter plates. For each of the filter plates, the respective outer rim may be tapered from the first face to the second face to provide the radial misalignment.

The present disclosure is related to hybrid desalination systems and associated methods. The hybrid desalination system can comprise a first desalination unit comprising a reverse osmosis unit and a second desalination unit fluidically connected to the first desalination unit, wherein the second desalination unit comprises a humidification-dehumidification desalination apparatus. The present disclosure is also related to systems and methods for the formation of solid salts using a humidifier. According to certain embodiments, the flow velocity of a gas in the humidifier can be relatively high during the formation of the solid salt. In some embodiments, the humidifier comprises a multi-stage bubble column humidifier.
