| Abstract: | The present invention relates to vacuum pressure swing adsorption (VPSA) process to recover carbon dioxide having a purity of more than 90% from streams containing at least carbon dioxide and nitrogen (e.g., flue gas from power plant). The feed to the CO2 VPSA can be at moderate temperature and at low CO2 partial pressures. The CO2 VPSA unit produces two streams, a high purity CO2 product suitable for sequestration and nitrogen enriched waste stream which can be vented . This invention highlights that CO2 product purity and recovery ,which are the key performance indicators of the VSA process ,depend on the arrangements of VSA cycle steps in a particular manner, apart from adsorbent properties. This has been leveraged in the present invention to get desired performance. Hence an improved multistep VSA cycle is designed and implemented in a custom designed fully automated PC/PLC based three columns apparatus to get high CO2 recovery with high purity suitable for sequestration. | ||
