Abstract:
A process for the production of electric energy and CO 2 from a hydrocarbon feedstock comprising steam reforming of the feedstock producing synthesis gas, wherein the synthesis gas is separated into a hydrogen rich and carbon lean stream and a rest stream, said hydrogen rich and carbon lean stream is combusted with compressed air for producing a combustion product which is expanded in a turbine generating electric energy, said rest stream is recirculated as fuel for producing heat for said steam reforming is described. Further a power plant for performing the process is described.
Abstract:
A process for the production of electric energy and CO2 from a hydrocarbon feedstock 1 comprising steam reforming of the feedstock producing synthesis gas (22) wherein the the synthesis gas is separated into a hydrogen rich and carbon lean stream (50) said hydrogen rich and carbon lean stream is combusted with compressed air for producing a combustion product which is expanded in a turbine (6) generating electric energy, said rest stream (50) is recirculated as fuel (52) for producing heat for said steam reforming is described. Further a power plant for performing the process is described.
Abstract:
The invention relates to a method for inter alia to increase the energy and cost efficiency of a gas power plant or a thermal heat plant with C0 2 capturing. The power plant comprises gas turbine plants (12,12') comprising compressor units (13,13') and turbine units (14,14') and further comprises a combustor (10). The combustor (10) is working in principle with to separate gas part streams where one gas part stream flows internally through the flame tube (40) of the combustor (10), while the other gas part stream is flowing along the exterior of the flame tube (40). The first gas part stream comprises additional air and re-circulated, uncleaned flue gas from the combustor (10), said gases being combusted together with fuel inside the flame tube (40). The second gas part stream comprises cleaned flue gas which is heated up at the exterior of the flame tube (40) while the flame tube (40) is cooled down. The invention comprises also a power plant, a combustor and a C0 2 capture plant.
Abstract:
A method of using biomass as supplementary firing in a combined cycle, combined heat and power plant comprising an internal combustion engine fired with fossil fuel and a steam engine, where steam for the steam engine is generated in a waste heat boiler for the flue gas from the internal combustion engine, and where the biomass is gasified in a gasification reactor to produce a biomass gas, where the biomass gas is carried hot from the gasification reactor and into an afterburner in the waste heat boiler, and combusted there. A combined heat and power plant for carrying out the method is also described.
