A PLANT AND PROCESS FOR RECOVERING CARBON DIOXIDE |
摘要 |
The present invention relates to a process and plant for the recovery of carbon dioxide from a gas stream by means of pressure swing adsorption using an adsorbent, such as X or Y type Zeolite adsorbents. The gas feed stream suitably has a moderate concentration of carbon dioxide, such as gas emitted from the filling bowl of the carbonated drinks bottling plant and is recovered without rinsing or purging the adsorbent with a high purity carbon dioxide gas stream. The process therefore provides the advantage of being capturing carbon dioxide from the effluent that would otherwise be emitted to the atmosphere and captures the carbon dioxide in a manner that minimises operational and capital expenditure. The present invention also relates to a process for utilizing one dry stream from a gas separation unit (adsorption or membrane process) to conduct evaporative cooling of water, which is used as the water in a liquid ring vacuum pump thereby decreasing the vacuum level and improving the performance.
