Abstract: A fuel, an oxidant, and a diluent can be introduced to a combustion zone, wherein the oxidant comprises air, oxygen-enriched air, or oxygen-lean air. At least a portion of the fuel can be combusted to produce an exhaust gas comprising, nitrogen, nitrogen oxides, and carbon monoxide. The exhaust gas can be expanded to produce mechanical power and an expanded exhaust gas. A concentration of at least one of oxygen, hydrogen, nitrogen oxides and carbon monoxide, in the exhaust gas or the expanded exhaust gas or both can be determined, and an amount of the oxidant or the fuel introduced to the combustion zone, or both, can be adjusted based on the determined concentration to produce an exhaust gas containing a combined amount of oxygen and carbon monoxide of less than about 2 mol % and a nitrogen concentration ranging from 20 mol % to 75 mol %.

Abstract: Methods and systems for low emission power generation in hydrocarbon recovery processes are provided. One system includes a gas turbine system configured to stoichiometrically combust a compressed oxidant derived from enriched air and a fuel in the presence of a compressed recycle exhaust gas and expand the discharge in an expander to generate a recycle exhaust stream and drive a main compressor. A boost compressor receives and increases the pressure of the recycle exhaust stream and prior to being compressed in a compressor configured to generate the compressed recycle exhaust gas. To promote the stoichiometric combustion of the fuel and increase the CO2 content in the recycle exhaust gas, the enriched air can have an increased oxygen concentration.

Abstract: Embodiments described herein provide a system and methods for the production of hydrocarbons. The method includes flowing a stream directly from a hydrocarbon reservoir to a cavern and performing a phase separation of the stream within the cavern to form an aqueous phase and an organic phase. The method also includes flowing at least a portion of the aqueous phase or the organic phase, or both, directly from the cavern to a subsurface location and offloading at least a portion of the organic phase from the cavern to a surface.

Abstract: Systems and methods for controlling the composition of a combustion exhaust gas are provided.

Abstract: A gas processing facility for the liquefaction of a natural gas feed stream is provided. The facility comprises a gas separation unit having at least one fractionation vessel. The gas separation unit employs adsorbent beds for adsorptive kinetic separation. The adsorbent beds release a methane-rich gas feed stream. The facility also includes a high-pressure expander cycle refrigeration system. The refrigeration system compresses the methane-rich gas feed stream to a pressure greater than about 1,000 psia. The refrigeration system also chills the methane-rich gas feed stream in one or more coolers, and then expands the chilled gas feed stream to form a liquefied product stream. Processes for liquefying a natural gas feed stream using AKS and a high-pressure expander cycle refrigeration system are also provided herein. Such processes allow for the formation of LNG using a facility having less weight than conventional facilities.

Abstract: The invention relates to the integration of a dehydroaromatization process with the processes for the utilization of associated gas; gases comprising methane and higher hydrocarbons, and/or liquefied natural gas (LNG) production or usage.

Abstract: The GTL process of the invention comprises: reacting a combustible carbonaceous material in a syngas reactor, preferably an autothermal reformer, under conditions to produce a synthesis gas; contacting the synthesis gas with an F-T catalyst to form liquid products and a tail gas; separating the tail gas from the liquid products; separating CO2 from the light products in the tail gas; recovering the light products as additional products for sale or other use and utilizing at least a portion of the separated CO2 as a feed stream to the syngas reactor.
