Abstract: Systems and methods are provided for improving separation of gas phase streams using an adsorbent, such as 8-member ring zeolite adsorbents or DDR type zeolite adsorbents. Suitable gas phase streams can include at least one hydrocarbon, such as methane or a hydrocarbon containing at least one saturated carbon-carbon bond, and at least one additional component, such as CO2 or N2. The selectivity of the adsorbent is improved by selectivating the adsorbent with one or more barrier compounds. The presence of the barrier compounds is believed to alter the relative ability of potential adsorbates to enter into and/or move within the pores of the adsorbent.

Abstract: A cyclic process for selectively separating hydrogen sulfide from a gas mixture including CO2 is operated by contacting the gas mixture under sorption conditions with a non-aqueous sorbent comprising a basic non-protogenic nitrogenous compound to react the H2S with the basic compound so that the H2S can be sorbed by the compound. The compound containing the sorbed H2S can then be subjected to desorption conditions by which the H2S is desorbed and the sorbent readied for another sorption step in the cycle. The basic nitrogenous compound can be carried on a porous solid sorbent, e.g., a solid oxide such as alumina, silica, silica-alumina, zeolites, or a mesoporous and/or macroporous solid oxide. The process may be operated using a pressure swing, temperature swing, partial pressure swing, purge displacement, or a combination thereof between the sorption and desorption portions of the cycle, preferably in a rapid cycle operation.

Abstract: The identification, synthesis, and use of an isomorphously substituted molecular sieve material having structural frameworks substituted with a preselected substitution element for a framework element of the molecular sieve material can result in a preferred transport controlling window size range for the optimal separation of a target gas component from a gaseous mixture containing said target gas component.

Abstract: A method for recovering oil from a subterranean, hydrocarbon-bearing formation includes at least one injection well and injecting a carrier fluid including a diverting agent into a high permeability pathway within the formation. An activating fluid is injected into the high permeability pathway within the formation, resulting in the precipitation or swelling of the diverting agent. The permeability of the high permeability pathway is decreased within the formation containing the diverting agent to a permeability less than the permeability of the adjacent areas of the formation. The carrier fluid may have a predetermined residence time within the formation prior to injecting an activating fluid; the step of injecting a carrier fluid comprising a diverting agent and injecting an activating fluid may be repeated. A mineralization fluid may be injected that is oversaturated or becomes oversaturated upon interacting with the acid gas that causes mineral precipitation to seal off high-permeability pathways.

Abstract: A temperature swing adsorption process for the removal of a target species, such as an acid gas, from a gas mixture, such as a natural gas stream. Herein, a novel multi-step temperature swing/pressure swing adsorption is utilized to operate while maintaining very high purity levels of contaminant removal from a product stream. The present process is particularly effective and beneficial in removing contaminants such as CO2 and/or H2S from a natural gas at relatively high adsorption pressures (e.g., at least 500 psig) to create product streams of very high purity (i.e., very low contaminant levels).

Abstract: A CO2 amine scrubbing process uses an absorbent mixture combination of an amine CO2 sorbent in combination with a non-nucleophilic, relatively stronger, typically nitrogenous, base. The weaker base(s) are nucleophilic and have the ability to react directly with the CO2 in the gas stream while the relatively stronger bases act as non-nucleophilic promoters for the reaction between the CO2 and the weaker base. The sorption and desorption temperatures can be varied by selection of the amine/base combination, permitting effective sorption temperatures of 70 to 90° C., favorable to scrubbing flue gas.
