Abstract:

Systems and methods for an oxy-fuel type combustion reaction are provided. In one or more embodiments, a combustion system can include at least two mixing zones, where a first mixing zone at least partially mixes oxygen and carbon dioxide to produce a first mixture and a second mixing zone at least partially mixes the first mixture with a fuel to produce a second mixture. The combustion system can also include a combustion zone configured to combust the second mixture to produce a combustion product. In one or more embodiments, the first mixture can have a spatially varied ratio of oxygen-to-carbon dioxide configured to generate a hot zone in the combustion zone to increase flame stability in the combustion zone.

US Classification:

96110

Abstract:

An adsorber with minimal dead volume especially suited to reverse-flow applications comprises: a) an adsorber body; b) a first head engaged with said adsorber body; c) a first conduit extending from outside said head to at least partially through said head; and d) a first valve in flow communication with said first conduit controlling fluid flow along a flow path extending from the first valve and through the adsorber body. The adsorber is especially suited for use in a process for swing adsorption separation processes.

International Classification:

F02C 3/34

US Classification:

60772, 60 3952

Abstract:

Methods and systems for low emission power generation in hydrocarbon recovery processes are provided. One system includes a gas turbine system configured to stoichiometrically combust a compressed oxidant and a fuel in the presence of a compressed recycle exhaust gas and expand the discharge in an expander to generate a gaseous exhaust stream and drive a main compressor. A boost compressor can receive and increase the pressure of the gaseous exhaust stream and inject it into an evaporative cooling tower configured to use an exhaust nitrogen gas having a low relative humidity as an evaporative cooling media. The cooled gaseous exhaust stream is then compressed and recirculated through the system as a diluent to moderate the temperature of the stoichiometric combustion.

US Classification:

60772, 60 3952

Abstract:

Methods and systems for low emission power generation in hydrocarbon recovery processes are provided. One system includes a gas turbine system configured to stoichiometrically combust a compressed oxidant derived from enriched air and a fuel in the presence of a compressed recycle exhaust gas and expand the discharge in an expander to generate a recycle exhaust stream and drive a main compressor. A boost compressor receives and increases the pressure of the recycle exhaust stream and prior to being compressed in a compressor configured to generate the compressed recycle exhaust gas. To promote the stoichiometric combustion of the fuel and increase the COcontent in the recycle exhaust gas, the enriched air can have an increased oxygen concentration.

International Classification:

F02C 3/34

US Classification:

60772, 60 3952

Abstract:

The present techniques are directed to a combustor for a gas turbine. For example, an embodiment provides a spool piece for the combustor. The spool piece includes an oxidant injection port configured for injection of an oxidant proximate to a flame in the combustor and a recycle-gas extraction port configured for an extraction of a recycle gas from the combustor, wherein the recycle gas is isolated from the oxidant prior to the use of the oxidant in a flame.

Abstract:

Provided are more efficient techniques for operating gas turbine systems. In one embodiment a gas turbine system comprises an oxidant system, a fuel system, a control system, and a number of combustors adapted to receive and combust an oxidant from the oxidant system and a fuel from the fuel system to produce an exhaust gas. The gas turbine system also includes a number of oxidant-flow adjustment devices, each of which are operatively associated with one of the combustors, wherein an oxidant-flow adjustment device is configured to independently regulate an oxidant flow rate into the associated combustor. An exhaust sensor is in communication with the control system. The exhaust sensor is adapted to measure at least one parameter of the exhaust gas, and the control system is configured to independently adjust each of the oxidant-flow adjustment devices based, at least in part, on the parameter measured by the exhaust sensor.
