    Abstract: A method for desalinating a liquid, including: contacting, within a hydrate former reactor, a feed gas stream including iso-butane in an amount ranging from above zero mol % to about 3 mol % and liquid seawater or liquid wastewater including a dissolved salt, wherein a temperature and pressure within the hydrate former reactor is controlled so that the feed gas stream and the liquid seawater or liquid wastewater form a hydrate slurry; separating hydrate particles from the hydrate slurry; and decomposing the hydrate particles into its constituents of water and gas or gas mixture containing iso-butane, wherein the water has a concentration of the dissolved salt that is less than that of the liquid seawater or liquid wastewater.

    Abstract: A method of evaluating subsurface connectivity, including: extracting biological material from samples obtained from a plurality of hydrocarbon wellbores, the biological material including nucleic acids, proteins, and lipids; determining microbial community structures based on the biological material, which includes determining an abundance of various species included in the samples; generating a reservoir connectivity analysis model, wherein the reservoir connectivity analysis model identifies a connectivity between at least two of the plurality of hydrocarbon wellbores in accordance with similarities in the microbial community structures at a plurality of subsurface locations that establish a path of fluid communication between the at least two of the plurality of hydrocarbon wellbores, wherein the reservoir connectivity analysis model includes a timing of the connectivity based on molecular biology; and generating a subsurface image or visualization, from the reservoir connectivity analysis model, that indicates a flow of hydrocarbons in the subsurface between the at least two hydrocarbon wellbores.

    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.
