20120055334 | METHOD FOR REMOVING OR DETOXIFYING GAS - A method for removing negatively-charged gas molecules includes the steps of: adsorbing negatively-charged gas molecules by a substrate carrying a positively-charged substance or a positively-charged substance and a negatively-charged substance on the surface of the substrate or in a surface layer of the substrate; and desorbing the aforementioned negatively-charged gas molecules adsorbed on the aforementioned substrate, from the substrate using a fluid.

20160032206 | PROCESS FOR REMOVING SULFUR COMPOUNDS FROM NATURAL GAS STREAMS - A process for the removal of sulfur compounds from a feed stream. A first separation zone removes sulfur compounds and produces a partially cleaned stream. A first adsorption zone adsorbs the remaining organic sulfur compounds on a regenerable adsorbent a produces a treated gas stream. A portion of the treated gas stream may regenerate the adsorbent in the first adsorption zone by removing organic sulfur compounds. The organic sulfur compound rich stream can be passed to a non-regenerable adsorption zone. The non-regenerable adsorption zone will separate out the organic sulfur compounds and provide a re-treated gas stream which may be recycled to a portion of the process. The non-regenerable adsorption zone may include regenerable adsorbent, but the zone is not operated to regenerate the adsorbent while it is in the non-regenerable adsorption zone. | 02-04-2016 |

20120222555 | Gas Purification Process Utilizing Engineered Small Particle Adsorbents - A gas separation process uses a structured particulate bed of adsorbent coated shapes/particles laid down in the bed in an ordered manner to simulate a monolith by providing longitudinally extensive gas passages by which the gas mixture to be separated can access the adsorbent material along the length of the particles. The particles can be laid down either directly in the bed or in locally structured packages/bundles which themselves are similarly oriented such that the bed particles behave similarly to a monolith but without at least some disadvantages. The adsorbent particles can be formed with a solid, non-porous core with the adsorbent formed as a thin, adherent coating on the exposed exterior surface. Particles may be formed as cylinders/hollow shapes to provide ready access to the adsorbent. The separation may be operated as a kinetic or equilibrium controlled process. | 09-06-2012 |
