摘要:
Systems and methods are disclosed herein for enhancing interoperability of a plant. Such systems and methods include a carbon emission, capture, transport, and usage model. The carbon emission, capture, transport, and usage model is capable of modeling interrelationships of inputs, outputs, and requirements between a carbon emitting plant, the carbon capture process, a carbon transportation system, and a carbon usage system. The carbon emitting plant is capable of producing a product having a carbonaceous substance. The carbon capture process is capable of capturing at least a portion of the carbonaceous substance from the product as a carbonaceous gas. The carbon transportation system is capable of transporting the carbonaceous gas from the carbon capture process to the carbon usage system. The carbon usage system is capable of receiving the carbonaceous gas transported by the carbon transportation system.

The disclosed embodiments provide systems for the removal and use of tar from a biomass gasification system. For example, in one embodiment, a biomass gasification system includes a reactor configured to gasify a biomass fuel in the presence of air to generate a producer gas. The system also includes an absorber configured to receive a mixture of the producer gas and tar and to absorb the tar into an organic solvent to produce treated producer gas and a rich solvent mixture containing at least a portion of the tar. The system further includes a recycle line configured to direct the rich solvent mixture to a biomass gasifier.
摘要:
A system includes a gasifier. The gasifier includes a chamber, a first nozzle, and a second nozzle. The first nozzle is configured to output a first fuel and a first oxidant to create a mixture that combusts in a combustion-reduction zone of the chamber. The second nozzle is configured to output a reduction promoter into the combustion-reduction zone to reduce combustion products in the combustion-reduction zone of the chamber.
摘要:
A method of assembling a combustion system includes providing a gas turbine engine that includes a gas turbine section coupled downstream from a combustion chamber and coupling a source of oxygen to the gas turbine engine such that a stream of oxygen discharged from the source facilitates displacing nitrogen in the working fluid of the gas turbine engine and facilitates decreasing emissions generated within the gas turbine engine.
摘要:
A plasma-assisted waste gasification system and process for converting waste stream reaction residues into a clean synthesis gas (syngas) is disclosed. The feedstock is fed into a reactor roughly one-third from the bottom through the use of a feed mechanism. The reactor has three zones; a bottom zone where melting occurs, a middle zone where gasification takes place, and a top zone with integrated plasma torches to control the temperature and polish the syngas. The residence times in the three zones are selected to optimize the syngas composition and melted products. The syngas leaves the reactor and is partially quenched with relatively cooler synthesis gas. The partially quenched syngas is further cooled to recover heat for steam generation and/or preheating the waste stream to the reactor. The cold syngas is then processed to remove pollutants. The clean synthesis gas is combusted in power generation equipment to generate electricity, or converted to other fuels by chemical processes.

The present application thus provides a gasifier for use in converting a feedstock material into a syngas. The gasifier may include an outer chamber, a reaction zone positioned within the outer chamber, and a disruption device maneuverable within the outer chamber to ensure a steady flow of the feedstock material into the reaction zone without bridging.
