Abstract:
1. A fractionation vessel for separating methane from a natural gas mixture, the vessel comprising: a housing; a gas inlet for receiving the natural gas mixture into the housing at a pressure of at least 100 psig; a first gas outlet for releasing at least a portion of the natural gas mixture from the housing; an adsorbent material within the housing, the adsorbent material having a kinetic selectivity for contaminants over methane greater than 5, such that the contaminants become kinetically adsorbed within the adsorbent material in gas phase; at least two major flow channels through the adsorbent material, the at least two major flow channels placing the gas inlet and the first gas outlet in fluid communication; and at least one minor flow channel through the adsorbent material, the at least one minor channel being in fluid communication with the major channels.
