Abstract: Improved adsorbent sheet based parallel passage adsorbent structures for enhancing the kinetic selectivity of certain kinetic-controlled adsorption processes, such as PSA, TSA and PPSA processes, and combinations thereof, are provided. The enhancements in kinetic selectivity made possible through the implementation of the present inventive improved adsorbent structures may unexpectedly enable significant intensification of selected kinetic adsorption processes relative to attainable performance with conventional adsorbent materials in beaded or extruded form. Such process intensification enabled by the present inventive adsorbent structures may provide for increased adsorption cycle frequencies, and increased gas flow velocities within the adsorbent beds, which may increase the productivity and/or recovery of a kinetic adsorption system incorporating the inventive adsorbent structures.

Abstract: An inventive improved parallel passage contactor structure demonstrating enhanced fluid flow performance is disclosed. Such improved parallel passage contactor structure may be adapted for many fluid/solid interaction processes such as catalytic gas reaction, fluid treatment, or adsorptive gas separation including pressure, temperature and partial pressure swing adsorption. Improved contactor structures according to the invention have Gas Flow Parameter values less than about 1.8E-4 Pa*s/m, which provide for enhanced process performance in applications such as adsorptive gas separation (holding other system variables constant). Some embodiments of the improved contactor structures incorporate improved mesh spacer materials having Open Volume Ratio values greater than about 85%.
