| 20090288557 | PROCESS AND ZEOLITIC MATERIALS FOR THE SEPARATION OF GASES - The present invention relates to a process for the separation of gases which comprises putting a mixture of gases in contact with a zeolite of the ESV type to obtain the selective adsorption of at least one of the gases forming the gaseous mixture. The present invention also relates to particular zeolitic compositions suitable as adsorbents. | 11-26-2009 |
| 20100139485 | GAS RECOVERY PROCESS - A method for concentrating a single gas component from a gas mixture is disclosed. The method utilizes concentration units and recovery units to concentrate the single gas component which is often at very low concentrations in the gas mixture. This method allows for the recovery of a valuable gas depending upon application such as oxygen and Ar-40. | 06-10-2010 |
| 20110005392 | PROCESS FOR SEPARATION OF CO2 BY PRESSURE-MODULATED ADSORPTION ON A POROUS CARBON SOLID - A process for separation of carbon dioxide that is present in a gas mixture by pressure-modulated adsorption (PSA) that comprises at least the following stages is described:
