20130092153, Apr 18, 2013

Filed:

Jul 3, 2011

Appl. No.:

13/576652

Inventors:

John Setel O'Donnell - Palo Alto CA, US
Peter Emery von Behrens - San Francisco CA, US
Stuart M. Heisler - Bakersfield CA, US

International Classification:

F24J 2/54
F24J 2/12
F24J 2/05

US Classification:

126600, 126694, 126652

Abstract:

Solar energy generates steam in a “once-through” configuration without recirculation, with closely managed steam quality, to produce wet steam from high-contaminant feed water without scaling or fouling. Feed water is pressurized, preheated, and evaporated in a series of pipes exposed to concentrated solar energy to produce a water-steam mixture for direct distribution to an industrial process such as enhanced oil recovery or desalination. Water flow rates are managed based on measurements of solar energy and steam production to manage variations in the solar energy. Steam generator piping system uses continuous receiver pipe that is illuminated by segmented parabolic mirrors enabled to track the sun. Provisions for steam generator piping recurring maintenance are provided. Thermal energy from hot condensate and/or from low quality steam is recaptured and warms inlet water.

International Classification:

E21B 43/24

US Classification:

166 57, 126684

Abstract:

Solar energy is collected and used for various industrial processes, such as oilfield applications, e.g. generating steam that is injected downhole, enabling enhanced oil recovery. Solar energy is indirectly collected using a heat transfer fluid in a solar collector, delivering heat to a heat exchanger that in turn delivers heat into oilfield feedwater, producing hotter water or steam. Solar energy is directly collected by directly generating steam with solar collectors, and then injecting the steam downhole. Solar energy is collected to preheat water that is then fed into fuel-fired steam generators that in turn produce steam for downhole injection. Solar energy is collected to produce electricity via a Rankine cycle turbine generator, and rejected heat warms feedwater for fuel-fired steam generators. Solar energy is collected (directly or indirectly) to deliver heat to a heater-treater, with optional fuel-fired additional heat generation.

International Classification:

F22B 1/00

F22B 1/22
F01K 3/24

Abstract:

Separators and mixers for delivering controlled-quality solar-generated steam over long distances for enhanced oil recovery, and associated systems and methods. A representative method includes heating water to steam at a solar field, separating a liquid fraction from the steam, directing the steam toward a target steam user via a first, steam conduit, and directing the liquid fraction toward the target steam user in parallel with the steam via second, liquid fraction conduit. The method can further include mixing the liquid fraction and the steam before delivering the combined liquid fraction and steam to the target user.

International Classification:

E21B 36/00

Abstract:

Systems and methods for variable rate steam injection, including via solar power for enhanced oil recovery, are disclosed. Several embodiments include using the variable nature of solar-generated steam to improve the efficiency and cost-effectiveness of enhanced oil recovery processes. In particular embodiments, the variable rate injection can provide more uniform steam distribution in an oil-bearing formation, at a lower cost than if the same amount of steam were provided on a continuous basis.

International Classification:

F03G 6/06
F28D 20/00

Abstract:

Heat storage devices for solar steam generation, including recirculation and desalination, and associated systems and methods are disclosed. A representative method includes directing a high temperature working fluid (a) from a thermal storage device to a solar field to heat the high temperature working fluid, and (b) back to the thermal storage device. The method can further include directing a first portion of the high temperature working fluid from the thermal storage device through a first branch of a high temperature working fluid loop to transfer heat to a process fluid at a first temperature. A second portion of the high temperature working fluid is directed from the thermal storage device through a second branch of the high temperature working fluid loop, in parallel with the first branch, to transfer heat to the process fluid at a second temperature less than the first temperature.
