摘要： The present disclosure relates to systems and methods useful for power production. In particular, a power production cycle utilizing CO2 as a working fluid may be configured for simultaneous hydrogen production. Beneficially, substantially all carbon arising from combustion in power production and hydrogen production is captured in the form of carbon dioxide. Further, produced hydrogen (optionally mixed with nitrogen received from an air separation unit) can be input as fuel in a gas turbine combined cycle unit for additional power production therein without any atmospheric CO2 discharge.

摘要： The present disclosure relates to a power production system that is adapted to achieve high efficiency power production using partial oxidation of a solid or liquid fuel to form a partially oxidized stream that comprises a fuel gas. This fuel gas stream can be one or more of quenched, filtered, and cooled before being directed to a combustor of a power production system as the combustion fuel. The partially oxidized stream is combined with a compressed recycle CO2 stream and oxygen. The combustion stream is expanded across a turbine to produce power and passed through a recuperator heat exchanger. The expanded and cooled exhaust stream can be further processed to provide the recycle CO2 stream, which is compressed and passed through one or more recuperator heat exchangers in a manner useful to provide increased efficiency to the combined systems.

摘要： The carbon dioxide membrane separation system in a coal gasification process contains introduction of a mixed gas of hydrogen (H2) and carbon dioxide (CO2) in a high temperature and high pressure condition generated through water gas shift reaction from a water gas shift reaction furnace, while maintaining the temperature and pressure condition, to a zeolite membrane module containing a zeolite membrane for removing carbon dioxide, thereby removing carbon dioxide and generating a fuel gas rich in hydrogen. The fuel gas rich in hydrogen in a high temperature and high pressure condition discharged from the zeolite membrane module is fed to a gas turbine of the power generation facility while maintaining the temperature and pressure condition.

摘要： A statorless axial turbine for a turbocharger has a turbine housing assembly defining a meridionally divided scroll extending circumferentially and surrounding the turbine wheel, the meridionally divided scroll defining a first scroll extending substantially fully about the turbine wheel and a separate second scroll extending substantially fully about the turbine wheel. The turbine housing assembly defines a separate inlet for each of the first and second scrolls through which a separate exhaust gas stream is received, and separate first and second outlets for each of the first and second scrolls, respectively, through which the respective exhaust gas streams are fed into an inlet side of the turbine wheel generally in an axial direction of the turbine wheel.
