  • Publication number: 20160158697
    Abstract: A method and apparatus for removing methane from ventilation air in a mining situation is provided by a carbonation reactor CAR which reacts a ventilation air methane stream VAR with a carbon dioxide scavenger to form a mineral carbonate which is passed to a calcination reactor CAL in which a regeneration reaction decomposes the mineral carbonate back to a mineral or mineral oxide. Additional heat may be added to the CAL by steam, solar energy or by burning drainage gas, natural gas, or coal. Steam or supercritical fluid given off by the CAR can be utilized for heating, cooling, or energy generation. The carbon dioxide scavenger can be any metal, metal oxide, mineral or mineral waste having a carbonation tendency, used in the process referred to as “Mineral Carbonate Looping Reactor” (MCLR), or can be stone dust from the mining site used in the process referred to as “Stone Dust Looping Reactor” (SDLR).

  • Patent number: 9346013
    Abstract: An integrated chemical looping air separation unit (5) in a large-scale oxy-fuel power generating plant takes a portion of recycled flue gas (6) via a recycling conduit (7) through a heat exchanger (8) to a reduction reactor (9). The reduction reactor (9) exchanges oxidized metal oxide with an oxidation reactor (11) via transfer means (10) which return reduced metal oxide from the reduction reactor (9) to the oxidation reactor (11). This enables the reduction reactor (9) to feed a mixture of oxygen and recycled flue gas into the boiler (13) of the power generating plant in a more energy efficient manner than conventional oxy-fuel power plants using air separation units.
