Using membranes for hydrogen separation from biorefinery off-gases has the following advantages over other separation technologies*:
- low energy consumption
- possibility to carry out separation continuously
- mild process conditions
- easy scale-up
- absence of additives
- can be combined with other separation technologies.
Air Products has extensive experience in membrane systems including our PRISM® hydrogen membranes.
