241 RC-BASED VAPOR TRAPS CASCADE US14096579 2013-12-04 US20150152748A1 2015-06-04 Mark Labinov
A method for tuning a system of cascade oscillating vapor traps to utilize the high-pressure condensate and produce intermittent power output on the basis of the physicochemical line of Retrograde Condensation in the two-phase zone. The method is based on usage of the “natural” frequencies, defined by the fluid on every point on said line and is radically different from the way steam traps are tuned presently.
242 METHOD FOR OPERATING A COMBINED-CYCLE POWER PLANT WITH COGENERATION, AND A COMBINED-CYCLE POWER PLANT FOR CARRYING OUT THE METHOD US14559338 2014-12-03 US20150082803A1 2015-03-26 Francois DROUX; Dario Ugo BRESCHI; Karl REYSER; Stefan ROFKA; Johannes WICK
The invention relates to a method for operation of a combined-cycle power plant with cogeneration, in which method combustion air is inducted in at least one gas turbine, and in which method the exhaust gas emerging from the at least one turbine is passed through a heat recovery steam generator (HRSG) in order to generate steam. The electricity production can be decoupled from the steam production in order to restrict the electricity production while the heat provided by steam extraction remains at a constant level. A portion of the inducted combustion air can be passed through at least one turbine to the HRSG without being involved in the combustion of the fuel in the gas turbine. This portion of the combustion air can be used to operate at least one supplementary firing in the heat recovery steam generator.
243 SYSTEMS AND METHODS FOR REDUCING PARASITIC LOSSES IN CLOSED LOOP SYSTEMS US14310856 2014-06-20 US20140373545A1 2014-12-25 Sankar K. Mohan
Embodiments of a system that configured as a closed loop system, with a pump, an evaporator, a power generator, and a condenser, the combination of which circulate a working fluid to generate electrical power. The embodiments can harvest residual energy in the working fluid to improve efficiency and to reduce power loss that can derive from the pump as well as other auxiliary loads (e.g., fans). In one embodiment, the system incorporates members that operate in response to the working fluid, often in the higher pressure vapor form that occurs after evaporation and/or power generation stages. These members can include mechanical elements, for example, that have motive action (e.g., reciprocate, rotate, etc.) that is useful to satisfy operating and power requirements of auxiliary loads. For the pressurization stage, these mechanical elements may embody a piston-and-cylinder arrangement (or other rotary or linear positive displacement arrangement) that generates motion that can drive the pump.

245 OILFIELD APPLICATION OF SOLAR ENERGY COLLECTION US14194919 2014-03-03 US20140345599A1 2014-11-27 John Setel O'Donnell; Peter Emery von Behrens; Stuart M. Heisler; David Bruce Jackson
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.

A second portion of the extracted working fluid may be introduced into the chamber defined within the expander rotor via a conduit defined in the thrust balance seal chamber. The second portion of extracted working fluid minimizes unequal axial thrust loads on the expander rotor due to the overhung arrangement.

Recycled exhaust gas from a power generation combustion reaction can be separated using a swing adsorption process so as to generate a high purity CO2 stream while reducing/minimizing the energy required for the separation and without having to reduce the temperature of the exhaust gas. This can allow for improved energy recovery while also generating high purity streams of carbon dioxide and nitrogen.

The invention relates to a method for operating a combined-cycle power plant with cogeneration, in which method combustion air is inducted in at least one gas turbine, is compressed and is fed to at least one combustion chamber for combustion of a fuel, and the resultant exhaust gas is expanded in at least one turbine producing work, and in which method the exhaust gas which emerges from the at least one turbine is fed through a heat recovery steam generator in order to generate steam, which heat recovery steam generator is part of a water-steam circuit with at least one steam turbine, a condenser, a feedwater tank and a feedwater pump, wherein heat is produced by extraction of steam from the at least one steam turbine. In a method such as this, simple decoupling of heat and electricity production, which is advantageous for operation, is achieved in that the steam can be selectively extracted from the at least one steam turbine as low-pressure steam or intermediate-pressure steam, and in that the steam extraction is switched from low-pressure steam to intermediate-pressure steam in order to restrict the electricity production.
