Polymeric Membranes for H2 and N2 Separation

Polymeric Membranes for H2 and N2 Separation

J. Wu, S. Japip, T.S. Chung

H2 and N2 separations are of paramount importance to the global development of clean energy and environment. While the traditional thermal-driven processes are often deemed overly energy-intensive, the polymeric membrane technology presents an energy-efficient and potentially cost-effective alternative that comes with many operational and environmental advantages to offer. However, a variety of key challenges revolving around the membrane performance and stability issues require new material innovations in order to be eventually overcome. This chapter provides the background for polymeric gas separation membranes and also a detailed evaluation on state-of-the-art polymeric membrane materials for H2 and N2 separations. Performance enhancement strategies will also be discussed in the later parts.
