A gas trap system for releasing gas-phase fluids is provided herein. The gas trap system is designed to reside within a return fluids tank, such as at a drill site. The gas trap system first includes a gas trap. The gas trap is configured to agitate drilling fluids in the return tank, and then to release gases during agitation. Liquids are circulated and released through a liquids exhaust port while gases are released through a gas exhaust port near the top of the gas trap. The gas trap system is configured to float along vertical guide rods in response to changes in height, weight and viscosity of the drilling fluids in the return tank. A method of capturing gaseous phase fluids from a fluid return is also provided herein. The fluid return is preferably drilling fluids at a drill site.

Gas-extraction device (152) for extracting at least one gas contained in a drilling mud, the device comprising: an enclosure (162), an equipment (164) for supplying the drilling mud to the enclosure (162), an equipment (170) for introducing a carrier gas into the enclosure (62; 162), wherein the device comprises a flow regulator (204) able to regulate the flow rate of a gas flow containing at least carrier gas, and a pressure controller situated downstream of the enclosure (162) configured for locally setting a pressure lower than the pressure of the enclosure (162), wherein the flow, regulator (204) is interposed between the pressure controller and the enclosure (162).

The inventive technology described herein includes a novel mechanical apparatus and system which allows centrifugation of small micron sized particles. The invention allows for continuous separation of ultrasound contrast agents (microbubbles) from lipid solution via centrifugation assisted by a motor. The system allows for mass isolation and collection of microbubbles. The invention also allows for the dispensation of lipid solution. In one preferred embodiment, dilute microbubble solution is introduced to the system and subjected to a centrifugal force such that the particles migrate towards the center and collectively rises for extraction, while the lipid solution dispenses and is replace with an equal volume of dilute solution. In one preferred embodiment, the device includes a rotating column or cylinder driven by a belt drive assembly, with the column being supported by annular bearings on both ends. The bearings allow rotation of the outer cylinder independent of stationary input cylinder and output components.

Systems for removing gas from a sealant and transferring gas-less sealant to an applicator are provided. The system may comprise: a rotatable chamber including: a first opening for receiving sealant; a hollow conduit arranged such that when gas accumulates in the center of the rotatable chamber when the rotatable chamber is rotating, the gas is ventable from the rotatable chamber; a second opening for receiving gas-less sealant from the rotatable chamber after the gas is vented from the hollow conduit; and a motor operatively configured to rotate the rotatable chamber; and a gas-less sealant applicator in fluid communication with the second opening of the rotatable chamber such that gas-less sealant released by the second opening is flowable into the applicator. The system may also include a robot arm including an end effector with a sealant dispensing nozzle. A method for applying sealant to an aircraft structure is also provided.

A product-lubricated multiphase pump for pumping a multiphase mixture containing hydrocarbon includes a separation system and a supply system. To achieve a good cooling and lubrication of pump elements without a lot of operating media and operating medium circuits, the separation system has a first separation stage for at least partly separating at least a portion of the multiphase mixture into a plurality of phase-enriched components and the supply system supplies a liquid-enriched liquid component as lubricant to a pump element to be lubricated.

A system for sulphur removal from a flue gas. The system includes an absorber, a reaction tank and a buffer tank. The buffer tank is connected to the reaction tank by a communicating vessel passage.

Systems and methods for extracting hydrocarbon gas utilize a vacuum chamber with a mud chamber portion that is expandable and contractible. Gas is extracted at vacuum pressures.

The invention relates generally to a de-aeration apparatus and system, and more particularly, to an apparatus and system suitable for de-aerating highly viscous fluids comprising a vacuum chamber, an annular disk for rotating within the chamber, and a fixed baffle covering a portion of the surface of the annular disk and thereby defining a predetermined path by which the fluid to be de-aerated is spread more quickly into a thinner layer on the disk, exposing a greater amount of air/gas bubbles from the fluid in a shorter amount of time and resulting in a higher quality product than conventional de-aeration systems allow.

A vacuum deaerator is provided with a refining device with which it is possible to suppress the occurrence of situations involving interrupted discharging and continuously discharge a material being treated that is highly viscous, etc. The vacuum deaerator introduces a liquid material being treated into a vessel having a vacuum therein to perform deaeration and then discharged the material being treated out of the vessel. A rotating rotor with refining device arranged in the vessel and a rotating discharge vane provided separately from the rotating rotor for the purpose of discharging the material being treated in the vessel out of the vessel are installed.
