Chapter 2. Pressure Swing Adsorption Processes Production Regeneration Figure 2.4: Two bed, four step, rapid pressure swing adsorption cycle 2.3.4 Multi-bed PSA Most of the modern PSA systems, in addition to the four basic steps, also have extra depressurization steps (see Figure 2.5) between the end of adsorption step and start of the regeneration step, and the corresponding pressure equalization steps between the end of regeneration step and start of the re-pressurization step. The main purpose of these steps is to properly utilize the high pressure product towards the bed end for pressurizing other columns. The number of such steps is highly dependent on the number of beds involved in a given PSA cycle. Furthermore, there are also examples of PSA cycles, which contains an extra idle step [165] , in addition to the above mentioned steps. During this step, there is no inflow or outflow of fluid from the PSA bed. The most important reason for inclusion of this step is to allow necessary time to synchronize the multiple bed assembly. However, it is important to note that this will inevitably cause the PSA productivity to go down. 2.3.5 Rotary Valve Pressure Swing Adsorption A recent addition to the PSA family is the rotary valve based PSA technology from Xebec Adsorption Inc [35], as depicted in Figure 2.6 1.
