Brackish Water Desalination Using a Mixed Bed of Anion Exchangers to Prevent Sulfate Scaling Without External Addition of Chemicals
SUMMARYLehigh University has developed a reversible ion exchange-desalination (RIX-D) process. Desalination is a common method of salt-water purification, which is practiced throughout the world. The two products of salt water purification drinking water and leftover salty brine called concentrate. Unfortunately, the amount of drinking water that c...

Autothermal Cycle for Co2 Capture
SUMMARY Lehigh University has developed a novel process for carbon capture. This process removes carbon dioxide from flue gas through beds containing adsorbent materials. Desorption is performed by passing steam through the beds creating a stream of carbon dioxide mixed with steam. This mixture is then compressed to condense the steam and move the ...

Supercapacitive Swing Adsorption
SUMMARY Lehigh University has developed a new approach to sorption based gas separation using supercapacitive swing adsorption (SSA). This approach is advantageous over traditional gas separation techniques as it avoids the need of pressure and temperature changes. Reusable supercapacitive energy is utilized to achieve gas separation suggesting sub...
