摘要:
The present application is directed to a method and system for preparing gaseous utility streams from gaseous process streams, particularly, removing oil contamination from such streams prior to use in a dry gas seal. The methods and systems may include at least one kinetic swing adsorption process including pressure swing adsorption, temperature swing adsorption, calcination, and inert purge processes to treat gaseous streams for use in dry gas seals of rotating equipment such as compressors, turbines and pumps and other utilities. The adsorbent materials used include a high surface area solid structured microporous and mesoporous materials.

摘要:
A pressure swing adsorption process for removal of CO2 from natural gas streams through a combination of a selective adsorbent material containing an effective amount of a non-adsorbent filler, adsorbent contactor design, and adsorption cycle design. The removal of contaminants from gas streams, preferably natural gas streams, using rapid-cycle swing adsorption processes, such as rapid-cycle pressure swing adsorption (RC-PSA). Separations at high pressure with high product recovery and/or high product purity are provided through a combination of judicious choices of adsorbent material, gas-solid contactor, system configuration, and cycle designs. For example, cycle designs that include steps of purge and staged blow-down as well as the inclusion of a mesopore filler in the adsorbent material significantly improves product (e.g., methane) recovery. An RC-PSA product with less than 10 ppm H2S can be produced from a natural gas feed stream that contains less than 1 mole percent H2S.

Adsorption of CO2 from flue gas streams using temperature swing adsorption. The resulting CO2 rich stream is compressed for sequestration into a subterranean formation and at least a portion of the heat of compression is used in the desorption step of the temperature swing adsorption process.

摘要:
The present invention relates to the separation of one or more of CO2, N2, and H2S gas components from a gas mixture containing at least a second gas using a swing adsorption process unit. The adsorbent contactors of the swing adsorption process unit are engineered structured adsorbent contactors having a plurality of flow channels wherein 20 volume percent or less of the open pore volume of the contactors is in the mesopore and macropore range.
