  • Patent number: 8480768
    Abstract: A gasifier 10 includes a first chemical process loop 12 having an exothermic oxidizer reactor 14 and an endothermic reducer reactor 16. CaS is oxidized in air in the oxidizer reactor 14 to form hot CaSO4 which is discharged to the reducer reactor 16. Hot CaSO4 and carbonaceous fuel received in the reducer reactor 16 undergo an endothermic reaction utilizing the heat content of the CaSO4, the carbonaceous fuel stripping the oxygen from the CaSO4 to form CaS and a CO rich syngas. The CaS is discharged to the oxidizer reactor 14 and the syngas is discharged to a second chemical process loop 52. The second chemical process loop 52 has a water-gas shift reactor 54 and a calciner 42. The CO of the syngas reacts with gaseous H2O in the shift reactor 54 to produce H2 and CO2. The CO2 is captured by CaO to form hot CaCO3 in an exothermic reaction.

  • Patent number: 8230796
    Abstract: A combustor 110 is operative to effect therewith the combustion of fossil fuel 114? in order to thereby both heat to a working fluid 102 and generate a flue gas 104. An air preheater 144 receives the flue gas 104 generated in the combustor 110. A blower 180 causes air 188 to flow to the air preheater 144 when operating in an air fired mode, and causes both O2 and recycled flue gas 188? to flow when operating in the O2 firing mode. The air preheater 144 is operative to transfer heat from the flue gas 150 received thereby to the air 188 that is received when operating in an air fired mode or to both the received O2 and the recycled flue gas 188? that is received when operating in the O2 firing mode in order to thereby effect a preheating of the air 188 or of both the O2 and recycled flue gas, 188? depending upon the specific nature of the mode of operation thereof, and to thereby effect therewith a cooling of the flue gas received thereby.

  • Patent number: 8196532
    Abstract: A combustor 110 combust a fluidized bed of fossil fuel 114, 114? to heat a working fluid 102 and generate flue gas 104. An air preheater 144 has first and second gas passageways 144a, 144b for respectively directing the generated flue gas 150 and another gas 250 with captured CO2 generated by combustion outside of the combustor 110. When operated in a non-CO2 capture, the air preheater 144 receives the flue gas 150, but not the other gas 250, and the first gas passageway 144a directs the flue gas 150 so as to preheat the air 188. However, when operated in the CO2 capture mode, the air preheater 144 receives the flue gas 150 and the other gas 250, and the second gas passageway 144b also directs the other gas 250 so as to preheat the air 188?. In either mode, the preheated air 188, 188? is applied by the combustor 110 to fluidize a bed of fossil fuel 114, 114?.

  • Patent number: 7896951
    Abstract: A system for reducing carbon dioxide emissions from gasses generated in burning fossil fuel, includes a vessel, separator and reheater. The upper portion of the vessel receives downward flowing, first type solid particles capable of absorbing heat from upward flowing gasses and second type solid particles capable of capturing carbon dioxide from the gasses. The separator separates the second type solid particles with the captured carbon dioxide from the gasses discharged from the first vessel discharge, and directs the separated second type solid particles with the captured carbon dioxide to a separator discharge. The reheater directs the first type solid particles and the second type solid particles with the captured carbon dioxide in a downwardly flow to a first reheater discharge, such that heat from the first type solid particles causes the captured carbon dioxide to be released from the second type solid particles.

    Abstract: A hot solids process operable selectively for combustion purposes and gasification purposes wherein a pre-identified product is selected from a group of products to be generated through the use of the hot solids process. Based on the nature of the pre-identified product, which is to be generated through the use of the hot solids process, a specific fuel from which the pre-identified product is capable of being derived is selected from a group of fuels. Then, from a group of reactors there is selected a first reactor, which is operable for generating in the first reactor the pre-identified product as an output from the first reactor. Thereafter, from a group of reactors, there is selected a second reactor, which is operable for effecting in the second reactor the conversion of air and of a predetermined carrier selected from a group of carriers to produce a predefined output from the second reactor.
