where dp is in cm. Finally, case 4 used the same correlations as case 3 to determine DL, but now film resistance was included according to equation 4.2. In all cases, Dp for nitrogen was found from equation 4.4 using typical literature correlations for Dm and Dk.24 A pore tortuosity (τp) of 3 was assumed since studies on larger LiLSX particles have estimated it between 2 and 4.28, 39, 42 The dimensionless Henry’s law coefficient (K) was found from previously determined DSL isotherm paramters52 assuming conditions of T = 313 K, P = 267 kPa, and a gas composition of 0.75/0.25 N2/O2 so the predictions are comparable to future experiments in this study. Table 4.1 summarizes the constants and correlations used in all four cases. Figure 4.2 demonstrates the koverall varies significantly depending on the assumptions made. As velocity increases, the controlling mass transfer limitation switches from axial dispersion control to macropore diffusion control. This is illustrated by the approach of koverall in Figure 4.2 to the horizontal “macropore only” line. As the koverall approaches the horizontal line, the macropore term in equation 4.1 becomes controlling. When koverall is far from the horizontal line, axial dispersion effects are controlling. It is evident the inclusion of film resistance has a noticeable impact on koverall if axial dispersion effects are low (Case 1 and 2). However, a higher axial dispersion coefficient has a much greater effect on koverall, especially at lower Reynolds numbers (Case 3 and 4) Small scale PSA processes often operate at low to moderate Reynolds 56PDF Image | LIMITS OF SMALL SCALE PRESSURE SWING ADSORPTION
