摘要： Gas turbine power plants augmented with an air injection system for hot air injection to augment power and are used to drive sensitive cogeneration processes are fitted with compressed air storage capability to more smoothly ramp on air injection in the event of sudden and unexpected interruption of the air injection system. Utilizing stored hot air injection prior to starting an air injection system significantly reduces the start-up time of the air injection system.

摘要： In a closed system that recirculates exhaust gas from a gas turbine engine, recirculated exhaust gas should be mixed into inlet gas in a manner that produces a uniform distribution within the mixed gas, while preventing an excessive pressure drop at the point of mixing, and without needing excessive duct length. Otherwise, the performance of the gas turbine engine may be detrimentally affected. Accordingly, a mixer box is disclosed that injects recirculated exhaust gas into a flow path of inlet gas in a uniform manner. The mixer box may comprise mixer(s) that extend the flow path of the recirculated exhaust gas into the flow path of the inlet gas along two axes. Each mixer may comprise surface apertures and/or interior channels designed to promote uniform ejection of the recirculated exhaust gas from the mixers into the flow path of inlet gas.

摘要： Electrical/mechanical power is derived from oxycombustion of hydrocarbons, preferably LNG, in a first of two nested cycles each operating on a Brayton cycle to provide a source of power, without mixing of working fluids between the two cycles. Each cycle employs CO2 as a working fluid, the first cycle operating under low pressure conditions in which CO2 is sub-critical, and the other cycle operating under higher pressure conditions in which CO2 is supercritical. The first cycle serves as a source of heat for the second cycle by gas/gas heat exchange which cools the products of combustion and circulating working fluid in the first cycle and heats working fluid in the second cycle.

摘要： The present invention provides methods and system for power generation using a high efficiency combustor in combination with a CO2 circulating fluid. The methods and systems advantageously can make use of a low pressure ratio power turbine and an economizer heat exchanger in specific embodiments. Additional low grade heat from an external source can be used to provide part of an amount of heat needed for heating the recycle CO2 circulating fluid. Fuel derived CO2 can be captured and delivered at pipeline pressure. Other impurities can be captured.

摘要： The present disclosure provides systems and methods for power production. In particular, the systems and methods utilize the addition of heat to an expanded turbine exhaust stream in order to increase the available quantity of heat for recuperation and use therein for heating a compressed carbon dioxide stream for recycle back to a combustor of the power production system and method.

摘要： A method for purifying an asphaltene-containing fuel where the asphaltene-containing fuel is supplied to a deasphalting unit in which asphaltene contained in the fuel is separated using a solvent, thereby forming a substantially deasphalted fuel. The solvent is separated from the deasphalted fuel in a solvent recovery unit after a successful separation of the asphaltene from the fuel, and the waste heat of turbine exhaust gas produced in a gas turbine when converting fuel into electricity is used in order to purify the asphaltene-containing fuel. A corresponding device is used for purifying an asphaltene-containing fuel.

摘要： The present invention is a system and method of power medium expansion that functions with a rate of efficiency higher than systems found in prior art. Novel features of the system increase the overall efficiency with the use of a power medium that begins the cycle in the liquid state and enters the gaseous state. An additional novel feature is the use of additional heat that may also increase the overall cycle efficiency. Another additional novel feature is recuperating energy that can supplement the phase change of the power medium along with isolating the components from the ambient.
