Transformational Membranes for Pre-Combustion Carbon Capture (Final Report)

Abstract

The objectives of this project are to develop a cost-effective design and fabrication process of a novel transformational membrane and its membrane modules that capture CO 2 from coal derived syngas. We have synthesized transformational membranes, scaled up the membrane to a prototype size of 14 inches wide by 20 feet in continuous roll-to-roll fabrication, fabricated at least 9 prototype membrane modules (each with about 2.5-inch diameter, 14-inch length, and 800 cm 2 membrane area) for testing with simulated syngas at OSU to achieve capture with at least 95% CO 2 purity. The membrane modules are in commercial spiral-wound (SW) configuration with a minimal pressure drop (<0.103 bar/meter (1.5 psi/meter)).
