Abstract: Systems and methods are provided for combined cycle power generation and enhanced hydrocarbon production where emission gases during power generation are separated by adsorption and applied to facilitate extraction of hydrocarbons from a reservoir. A power generation plant passes exhaust gas to a first swing adsorption reactor. The first swing adsorption reactor adsorbs the CO2 from the exhaust gas. An adsorption cycle of the first swing adsorption reactor is variable. An injection well injects the CO2 adsorbed by the first swing adsorption reactor in a hydrocarbon reservoir. A production well that is in communication with the injection well produces a mixture of hydrocarbons and CO2. A second swing adsorption reactor purifies the produced hydrocarbons by adsorbing the produced CO2 from the production well.The purified hydrocarbons are fed back to the power generation plant where combustion occurs and power is generated.

Abstract: Systems and methods are provided for combined cycle power generation while reducing or mitigating emissions during power generation. Recycled exhaust gas from a molten carbonate fuel cell power generation reaction can be separated by using a swing adsorption process so as to generate a high purity CO2 stream while reducing or minimizing the energy required for the separation and without having to reduce the temperature of the exhaust gas. A high temperature adsorption reactor adsorbs the CO2 and recovers H2 from an exhaust gas of a first molten carbonate fuel cell at a high temperature and at a low pressure. The reactor passes along the adsorbed CO2 to a cathode and the recovered H2 to an anode of a second molten carbonate fuel cell for further power generation. This can allow for improved energy recovery while also generating high purity streams of CO2 and H2.

Abstract: A method for capturing emissions from a fuel combustion process comprising: providing a fuel to a combustor on a gas turbine, providing an oxidant to the combustor, combusting the fuel and the oxidant in the combustor to produce an exhaust gas, passing at least a portion of the exhaust gas to one or more catalyst beds. The one or more catalyst beds promote a reaction which consumes CO and produces CO2 and adsorb CO2. Pressure at the catalyst beds is reduced by outputting a blow down stream from the catalyst beds and then CO2 is purged from the one or more catalyst beds with a regenerant stream to create a product stream.

Abstract: Systems and methods for using pressure swing adsorption to separate and/or capture resulting emissions are provided. A stream of recycled exhaust gas is passed into a first swing adsorption reactor comprising a first adsorbent material which adsorbs CO2. An enriched N2 stream is recovered from a forward end of the first swing adsorption reactor. The pressure in the first swing adsorption reactor is reduced. The first swing adsorption reactor is purged with a portion of the first N2 stream recovered from the first swing adsorption reactor. The first purge output is passed to a second swing adsorption reactor comprising a second adsorbent material which adsorbs CO2. A second N2 stream is recovered from the second swing adsorption reactor. The pressure in the second swing adsorption reactor is reduced. The second swing adsorption reactor is purged with a steam purge.
