Figure 4.2 Comparison of predicted overall nitrogen MTC using constants and correlations according to Table 4.1. Overall gas pressure = 267 kPa, gas composition (N2/O2) = 75/25 4.2 Small Scale PSA Small scale PSA is an advancement of PSA technology for the purpose of process size reduction. It is typically distinguished from traditional PSA by rapid cycling (< 30 seconds) of small adsorbent particles (< 1 mm). Larger scale PSA typically operates with cycle times on the order of minutes and a particle size > 1.5mm. Cycle time reduction requires an increase in gas velocity for a given amount of adsorbent. This raises several issues such as sorbent fluidization, increase in column pressure drop, and higher gas dispersion.12 In addition, a higher gas velocity reduces contact time with the solid, necessitating smaller adsorbent particles (<1mm). For a finite adsorption rate, the result 58PDF Image | LIMITS OF SMALL SCALE PRESSURE SWING ADSORPTION
