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.

Fluid for use in power production environments

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.

A steam generator apparatus for generating steam from a feedwater inlet stream including impurities is disclosed. The apparatus includes a tubing circuit in communication with an inlet for receiving the feedwater stream, the tubing circuit having a substantially unrifled bore defined by a metal wall, and a heat source operable to deliver a heat flux to the feedwater stream through the metal wall of the tubing circuit, the heat flux being operable to cause evaporation of feedwater within the tubing circuit and to produce an outlet stream at an outlet of the tubing circuit, the outlet stream includes a steam portion and liquid phase portion, the steam portion being greater than about 80% of the outlet stream by mass, the steam portion providing sufficient cooling of the metal wall to maintain a wall temperature at less than a threshold temperature associated with safe operation of the steam generator apparatus.

Steam generator and method for generating steam

A method for generating steam from a feedwater inlet stream including impurities is disclosed. The method involves receiving the feedwater inlet stream at an inlet of a steam generator and causing the feedwater stream to flow through a tubing circuit to an outlet of the tubing circuit, the tubing circuit having a substantially un-rifled bore defined by a metal wall. The method also involves delivering a heat flux to the feedwater stream through the metal wall of the tubing circuit to generate steam by causing evaporation of feedwater within the tubing circuit, and controlling at least one of a flow rate of the feedwater stream and the heat flux to cause generation of an outlet stream at the outlet includes a steam portion and liquid phase portion, the steam portion being greater than about 80% of the outlet stream by mass. The steam portion provides sufficient cooling of the metal wall to maintain a wall temperature at less than a threshold temperature.

Apparatus and methods for conveying a flow of oil-containing liquid into an oil separation skim tank, and a skim tank incorporating such apparatus and methods, are disclosed. One such apparatus includes at least one diffuser, the diffuser defining an intake opening configured to receive the flow of oil-containing liquid and an exhaust opening configured to convey the flow of oil-containing liquid into the skim tank. The diffuser is configured to cause the flow of oil-containing liquid to have a greater horizontal width at the exhaust opening than at the intake opening, while minimizing vertical divergence of the flow at the exhaust opening.

A thermally integrated fuel cell system includes a stack zone, a burner zone and a low temperature zone. The fuel is combined with steam and passed sequentially through a primary reformer and a secondary reformer or a radiative fuel heat exchanger. Air may be passed sequentially through an afterburner heat exchanger and a radiative air heat exchanger such that the radiative heat exchanger may be used to heat the stack zone. The stack exhaust is combusted in an afterburner. Afterburner exhaust heats the primary reformer, the high temperature air heat exchanger, the low temperature air heat exchanger and steam generator. The stack zone includes the stacks, the secondary reformer and the radiative heat exchanger. The burner zone includes the afterburner which includes a start burner, the primary reformer and the high temperature air heat exchanger. The low temperature zone includes the low temperature air heat exchanger and a steam generator.

Thermally integrated fuel cell system

A thermally integrated fuel cell system includes a stack zone, a burner zone and a low temperature zone. The fuel is combined with steam and passed sequentially through a primary reformer and a secondary reformer. Air is split into two parallel streams and preheated in a low temperature heat exchanger. One air stream passes to a high temperature heat exchanger while the other passes to a radiative heat exchanger. The air and fuel streams are equalized in an equalization heat exchanger before entering the fuel cell stacks. The stack exhaust is combusted in an afterburner. Afterburner exhaust heats the primary reformer, the high temperature heat exchanger, the low temperature heat exchanger and steam generator. The stack zone includes the stacks, the secondary reformer, the radiative heat exchanger and the equalization heat exchanger. The burner zone includes the afterburner, the primary reformer and the high temperature heat exchanger. The low temperature zone includes the low temperature heat exchanger and the steam generator.

Thermally integrated fuel cell stack

An enclosure for a fuel cell stack for insulating the hot zone of the fuel cell stack and for exchanging heat from the fuel cell stack to a reactant that passes through the enclosure to be used by the fuel cell stack. The enclosure comprises at least one chamber having an intake means for the reactant and an exhaust means for passing the reactant to the fuel cell stack. In one embodiment there are three layered chambers.
