| 20110120012 | MINIMAL SOUR GAS EMISSION FOR AN INTEGRATED GASIFICATION COMBINED CYCLE COMPLEX - Disclosed is a process to start-up, operate, and shut down a gasifier and an integrated gasification combined cycle complex with minimal sour gas emissions while additionally reducing the release of contaminants such as carbon monoxide, hydrogen sulfide, and nitrogen oxides. The process is accomplished by starting up with a sulfur free feedstock and by scrubbing any ventable sour gases free of sulfur contaminants prior to release of any such gases to the atmosphere. | 05-26-2011 |
| 20110070135 | Processes and Apparatuses for Purifying Greenhouse Gases - This invention relates to processes and apparatuses for purifying greenhouse gases. This invention relates to processes and apparatuses for drying carbon dioxide and/or producing syngas. The process includes the step of contacting a greenhouse gas stream having a contaminant with a solvent stream to at least partially reduce an amount of the contaminant and form a used solvent stream. The process includes the step of using the greenhouse gas stream for carbon sequestration, enhanced oil recovery, industrial gas supply, or chemical synthesis and production. | 03-24-2011 |
