Figure 6. Optimized purity-recovery Pareto frontiers for UiO-66 (blue) and MIL-101(Cr) (green) fiber sorbents for sub-ambient PSA operation at 243 K. The inset shows points within the desired range of purity and recovery. Starred points (with identical color schemes) indicate conditions used in separate case studies.
