Abstract

This Small Business Innovation Research (SBIR) Phase I project will develop a gas permeation process and membrane to separate olefin/paraffin mixtures in which a multilayer multifunctional membrane configuration ensures high selectivity, high olefin productivity, good mechanical stability, excellent impurity tolerability, and long-term operational reliability. Hollow fiber membrane modules will be developed to enhance the olefin permeance 2~10-fold compared to those by conventional polymer facilitated transport membranes in addition to much enhanced olefin/paraffin selectivity. This membrane system has long-term stability and reliability to dry feed containing trace amounts of H2, C2H2, and/or H2S that cannot be treated by traditional membrane processes.
