Adsorption-Enhanced Composite Membranes

Pic 01

CO2-Selective Membranes

Polymer-nanocrystal composite membranes provide improved CO2/X (X = CH4, N2, H2) selectivity, CO2 permeance, as well as increased robustness under harsh feed conditions. Using established solution-based processing techniques, this membrane format can be scaled to thousands of square meters of membrane area in a modular, spiral-wound assembly, for large scale applications.

Gas Processing Applications

Adsorption-enhanced composite membranes can be used for acid gas removal from raw natural gas, biogas upgrading to pipeline-quality biomethane, and H2 purification in syngas applications. In each of these, Flux CO2-selective membranes operate at very high selectivity and permeance, which translates to maximized product recovery and small operation footprint.
