摘要： A combustor apparatus is provided, comprising a mixing arrangement for mixing a carbonaceous fuel with enriched oxygen and a working fluid to form a fuel mixture. A combustion chamber is at least partially defined by a porous perimetric transpiration member, at least partially surrounded by a pressure containment member. The combustion chamber has longitudinally spaced apart inlet and outlet portions. The fuel mixture is received by the inlet portion for combustion within the combustion chamber at a combustion temperature to form a combustion product.

摘要： A first contaminant selected from oxygen and carbon monoxide is removed from impure liquid carbon dioxide using a mass transfer separation column system which is reboiled by indirect heat exchange against crude carbon dioxide fluid, the impure liquid carbon dioxide having a greater concentration of carbon dioxide than the crude carbon dioxide fluid. The invention has particular application in the recovery of carbon dioxide from flue gas generated in an oxyfuel combustion process or waste gas from a hydrogen PSA process. Advantages include reducing the level of the first contaminant to not more than 1000 ppm.

摘要： A method and bed for separating a reactive gas from a feed gas mixture is disclosed. The method includes reacting the reactive gas with a bed of reactive solid in an exothermic reaction to create a second solid and a product gas from which the reactive gas is depleted. The product gas is removed and the heat from the reaction is used to liberate the reactive gas from the second solid in an endothermic reaction which yields the reactive solid. The reactive gas is removed and sequestered. Heat reservoir material is included in the bed to retain the heat in support of the endothermic reaction. A device for executing the method having an insulated chamber holding the bed, as well as process units formed of multiple beds are also disclosed. The process units allow the method to be operated cyclically, providing a continuous flow of feed gas, reactive gas and product gas.

摘要： A process and apparatus for the production of low pressure gaseous oxygen (“GOX”) in which compressed and purified feed air (1) is cooled and at least partially condensed in heat exchange means (E1) having a warm end and a cold end and the cooled and at least partially condensed feed air (2) is then distilled in a cryogenic distillation column system (C1, C2). A liquid oxygen (“LOX”) product stream (8) is removed from the column system (C1, C2) and vaporized and warmed by heat exchange (E1) to produce GOX.

摘要： The present disclosure relates to systems and methods that provide a low pressure liquid CO2 stream. In particular, the present disclosure provides systems and methods wherein a high pressure CO2 stream, such as a recycle CO2 stream from a power production process using predominately CO2 as a working fluid, can be divided such that a portion thereof can be expanded and used as a cooling stream in a heat exchanger to cool the remaining portion of the high pressure CO2 stream, which can then be expanded to form a low pressure CO2 stream, which may be in a mixed form with CO2 vapor. The systems and methods can be utilized to provide net CO2 from combustion in a liquid form that is easily transportable.
