Abstract: Fluid classes for use in energy recovery in well and geothermal environments for power production are disclosed. The fluids fall into the classes of fluids being capable of increasing thermodynamic efficiency of electricity and/or heat generation from a closed-loop geothermal system. Numerous methods are disclosed which exploit the thermodynamics of the fluids for optimum energy recovery.

Abstract: Described herein are devices and methods for rotating a container (e.g., a capped tube containing a sample). The disclosure provides devices and methods of rotating a container using one motor, resulting in a less complex device. The device moves and rotates a container rotating member which in turn is used to rotate a container. The devices can be used in automated analytical instruments (e.g., automated blood analyzers) that automatically transport and detect the identity of sample containers. The devices can also be used in instruments that automatically spin sample containers to mix or homogenize the sample.

Abstract: Valves, pumps, detectors, sample loops, fraction collectors and the like are individually incorporated into modules that are mountable at individual mounting sites on a base unit which also supports one or more chromatography columns. Each module includes fluid connections to other modules and a microcontroller joining the module to a computed and monitor through an electronic connector at each mounting site. The fluid connections between the modules and the column(s) are removed from the electronic connections and accessible to the user. A software platform may recognize the modules and their locations, coordinate fluid connections between the modules, and provide a variety of control, monitoring, data generating and data processing functions to generate chromatographic data. The software platform may also provide graphical tools for designing chromatographic methods from a library of phases.

Abstract: In one arrangement, a cartridge includes a cartridge body defining a holding compartment, first and second fractioning compartments, and a number of flow channels formed within the cartridge body. A predetermined quantity of fluid can be held in the holding compartment when the cartridge body is held in a first orientation, and can be poured from the holding compartment to the first fractioning compartment by rotating the cartridge body about a predefined rotation axis to a second orientation, spilling the fluid from the holding compartment to the first fractioning compartment through one of the flow channels. The first fractioning compartment is such that when the cartridge body is in the second orientation, not all of the fluid can be contained in the first fractioning compartment, and fluid that overflows the first fractioning compartment flows through a second flow channel to the second fractioning compartment.

Abstract: A system and method for adjusting a position of an oil-water interface layer. A vessel, such as a free water knockout or a treater used in the processing of heavy oil, contains a fluid comprising the interface layer. A nuclear densitometer is positioned to obtain density measurements of the fluid at various heights along the vessel. Based at least in part on these density readings, a valve controlling flow out of a water discharge port on the vessel may be actuated, with the flow of water through the water discharge port being inversely proportional to the height of the interface layer.

Abstract: A system for fluid manipulation includes a composite wafer and a movable compression device. The composite wafer includes a flexible layer and a substantially rigid layer adhered to the flexible layer. The flexible layer defines one or more recesses that are covered by the substantially rigid layer to form one or more reservoirs and one or more fluid channels among the one or more reservoirs. The movable compression device contacts the flexible layer and is configured to progressively compress the flexible layer such that when the movable compression device traverses the flexible layer, fluid is forced through the one or more fluid channels and the one or more reservoirs in a sequence determined by the layout of the one or more fluid channels and the one or more reservoirs. Certain reservoirs may be pre-loaded with fluids and reagents for performing a specified medical test.
