Multi-element membrane assembly for selective carbon capture

Abstract

The present disclosure provides multi-element membrane assemblies for selective separation and capture of gaseous effluents. The assemblies may include stacked membrane units in, for example, either cubic or cylindrical configurations, providing high surface-area-to-volume ratios and thermal stability. The cubic configuration comprises flat membrane panels with metallic borders and support stringers, while the cylindrical configuration comprises toroid segments with thermally compatible gaskets. Both configurations maintain hermetic seals at elevated temperatures and provide efficient gas flow channels for feed and permeant gases. Manufacturing methods include pressing, casting, and additive manufacturing techniques. The assemblies are particularly suitable for separating carbon dioxide from high-temperature gas mixtures using lithium zirconate membranes.
