    Abstract: An adsorption module and associated processes for conducting advanced separations processes such as sorption enhanced water-gas shift (SEWGS). The adsorption module contains at least one angled baffle to create at least two tapered adsorbent beds within the adsorption module. The taper is such that the adsorbent beds' cross-sections within the adsorption module decrease in the direction of feed flow, thereby taking advantage of increased product purity and process efficiency provided by tapered adsorption beds.

    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 CO 2 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 CO 2 and recovers H 2 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 CO 2 to a cathode and the recovered H 2 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 CO 2 and H 2 .

    Abstract: Partition coefficients for solutes in solvent-water systems are estimated based on corresponding values for the octanol-water system. The estimation of the partition coefficient includes correction factors based on the nature of the solute and the solvent. Petroleum fractions are an example of a suitable solvent for which a partition coefficient can be estimated, although other types of solvents can be used in developing a model for use in the estimation.

    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 CO 2 . Pressure at the catalyst beds is reduced by outputting a blow down stream from the catalyst beds and then CO 2 is purged from the one or more catalyst beds with a regenerant stream to create a product stream.

    Abstract: Systems and methods are provided for performing multistage naphtha reforming with intermediate separation of aromatics using a swing adsorption process. Use of a swing adsorption process can allow aromatics to be selectively removed from the intermediate reforming effluent while reducing or minimizing the energy costs for cooling and subsequent reheating of the intermediate reforming effluent. The resulting aromatics-rich stream generated from swing adsorption can have a substantially higher aromatics content than an aromatics-rich stream generated by conventional separation methods during multi-stage naphtha reforming. In some aspects, selective thermal purging (either hot or cold) can be used to further facilitate adsorption or desorption of components by the adsorbent in the swing adsorption vessel.

    Abstract: In various aspects, apparatuses and methods are provided for low pressure drop gas separations. In PSA processes, where there are large swings in pressure and corresponding swings in fluid velocity through the adsorbent, mechanical stresses during pressure cycling are of considerable concern. When that pressure is relieved in a lower pressure portion of the cycle, the high velocity of gas moving through the adsorbent bed can erode, strip away, or otherwise damage the channels within the adsorbent. Provided herein are methods which utilize flexible boundaries between adsorbent beds that are operated out of phase with one another. The flexible boundaries permit an increase in void space through the adsorbent during high pressure stages of the cycle and a decrease in void space through the adsorbent during low pressure stages of the cycle.

    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 CO 2 from the exhaust gas. An adsorption cycle of the first swing adsorption reactor is variable. An injection well injects the CO 2 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 CO 2 . A second swing adsorption reactor purifies the produced hydrocarbons by adsorbing the produced CO 2 from the production well. The purified hydrocarbons are fed back to the power generation plant where combustion occurs and power is generated.
