The present disclosure relates to a power production system that is adapted to achieve high efficiency power production with carbon capture when using a solid or liquid hydrocarbon or carbonaceous fuel. More particularly, the solid or liquid fuel first is partially oxidized in a partial oxidation reactor that is configured to provide an output stream that is enriched in methane content. The resulting partially oxidized stream can be cooled, filtered, additionally cooled, and then directed to a combustor of a power production system as the combustion fuel. The partially oxidized stream is combined with a compressed recycle CO.sub.2 stream and oxygen. The combustion stream is expanded across a turbine to produce power and passed through a recuperator heat exchanger. The recycle CO.sub.2 stream is compressed and passed through the recuperator heat exchanger and optionally the POX heat exchanger in a manner useful to provide increased efficiency to the combined systems.

A process for reducing pressure of a vapor stream wherein the vapor stream rotates a turbine wheel within the turbine to transmit rotational movement to an electrical generator and generate electricity. The resulting lower pressure vapor stream reduces a partial pressure of a hydrocarbon vapor or is injected into a reactor to reduce a temperature in the reactor. A recovered electric power measuring system comprises at least one processor; at least one memory storing computer-executable instructions; and at least one receiver configured to receive data from a sensor on an electrical powerline connected to a generator of a turbine, the turbine in fluid communication with a vapor stream wherein the turbine reduces the pressure of the vapor stream and the resulting lower pressure vapor stream is injected into a reactor to reduce a temperature in the reactor or to reduce a partial pressure of hydrocarbon vapor in the reactor.

A process is provided for recycling Hydrogen enrichment tail gas to a combined cycle power system.

Oxy-fuel combustion of a fuel stream, an oxygen stream and a recycle stream can form an exhaust stream, with, for example, a gas turbine. The exhaust stream can be separated into a water-rich stream and a carbon dioxide-rich stream. At least a portion of the carbon dioxide-rich stream can be divided to form the recycle stream. A second portion of the carbon dioxide-rich stream and a hydrogen stream can generate an exit stream, with, for example, a Sabatier reactor. The exit stream can be separated into a methane-rich gaseous product and a water-rich liquid product.

The invention relates to a process and system for converting carbon material into power. Carbon material 12 is gasified into synthesis gas 18 in a gasifier 16, and steam 14 is supplied to the gasifier 16. The synthesis gas 18 is supplied to a gas turbine 30, 36, 38 to produce power. Air 24 is added to the synthesis gas 18 prior to the gas turbine 30, 36, 38. Exhaust gas 40 from the gas turbine 30, 36, 38 is cooled in a first cooling device 42 with water 46 to produce steam 52. The steam is used in at least one steam turbine to produce power 56 and the steam 58 from at least one steam turbine 56 is recycled to the gasifier 16.

A chemical looping combustion (CLC) based power generation, particularly using liquid fuel, ensures substantially complete fuel combustion and provides electrical efficiency without exposing metal oxide based oxygen carrier to high temperature redox process. An integrated fuel gasification (reforming)-CLC-followed by power generation model is provided involving (i) a gasification island, (ii) CLC island, (iii) heat recovery unit, and (iv) power generation system. To improve electrical efficiency, a fraction of the gasified fuel may be directly fed, or bypass the CLC, to a combustor upstream of one or more gas turbines. This splitting approach ensures higher temperature (efficiency) in the gas turbine inlet. The inert mass ratio, air flow rate to the oxidation reactor, and pressure of the system may be tailored to affect the performance of the integrated CLC system and process.
