| 20110286909 | Generation Of CO Using Off-Gas As Source - A method for generating CO using an off-gas as a source is provided. This method includes providing an off-gas feed stream, wherein said off-gas feed stream comprises CO | 11-24-2011 |
| 20110097260 | Hydrogen Recovery And Methane Production From Residual Fuels and Biomass - A method of hydrogen and methane recovery from syngas from a gasifier is provided. Then directing a raw syngas stream from an acid gas removal system to a CO and methane removal system. Then returning the CO and methane stream to the gasifier, and exporting the hydrogen stream as a product. | 04-28-2011 |
| 20110085966 | High Hydrogen Recovery From Residual Fuels And Biomass - A method of high hydrogen recovery from syngas from a gasifier is provided. This method includes providing a syngas stream from the gasifier to first hydrogen separation device, wherein the first hydrogen separation device is a pressure swing adsorption device, thereby producing a first high purity hydrogen stream and a tailgas stream. This method also includes increasing the pressure of the tailgas stream in a first compressor; thereby producing a pressurized tailgas stream. This method also includes providing the pressurized tailgas stream to a second hydrogen separation device, thereby producing a second high purity hydrogen stream and a residue stream. This method also includes directing the residue stream to an auxiliary boiler, and combining the first high purity hydrogen product stream and the second high purity hydrogen product stream, thereby producing a high purity hydrogen product stream. | 04-14-2011 |
| 20090013717 | PROCESS AND APPARATUS FOR THE SEPARATION OF A GASEOUS MIXTURE - A process for separating carbon dioxide from a carbon dioxide containing fluid comprises the steps of: compressing the fluid in a compressor to form a compressed fluid, drying at least part of the compressed fluid to form a compressed and dried fluid, cooling at least part of the compressed and dried fluid to form a compressed, dried and cooled fluid, separating the compressed, dried and cooled fluid at a temperature lower than 0° C. into a carbon dioxide rich stream, a carbon dioxide lean stream and at least one intermediate purity liquid stream having a carbon dioxide purity lower than that of the carbon dioxide rich stream and higher than that of the carbon dioxide lean stream, expanding at least one intermediate purity liquid stream to produce at least one expanded stream using at least one expanded stream to cool the compressed and dried fluid and recycling at least part of the expanded stream. | 01-15-2009 |
