A process for synthesizing polymer of intrinsic microporosity (PIM) for highly selective gas separation.
About
Georgia Tech and King Abdullah University researchers have designed and synthesized a novel amidoxime functionalized polymer of intrinsic microporosity (AO-PIM) for gas separation. Pure gas permeation tests show that the new AO-PIM membranes are more permeable than conventional glassy polyimide films, used in current separation techniques. Mixed gas permeation tests show that the membranes have excellent gas separation performance in high-pressure environments. The membranes have shown excellent Hydrogen Sulfide separation in particular.
Key Benefits
Energy Efficient – Greater energy efficiency than current gas separation techniques for acidic gases Ecofriendly – Allows for easy removal of acidic, ‘sour’, gas from emissions Scalable – Easy to scale-up process for industry Flexible – Synthesizing process allows for operational flexibility
Applications
