  • System and process for capture of acid gasses at elevated pressure from gaseous process streams
    Patent number: 9433892
    Abstract: A system, method, and material that enables the pressure-activated reversible chemical capture of acid gasses such as CO2 from gas volumes such as streams, flows or any other volume. Once the acid gas is chemically captured, the resulting product typically a zwitterionic salt, can be subjected to a reduced pressure whereupon the resulting product will release the captures acid gas and the capture material will be regenerated. The invention includes this process as well as the materials and systems for carrying out and enabling this process.

  • System and process for capture of HS from gaseous process streams and process for regeneration of the capture agent
    Patent number: 8652237
    Abstract: A system and process are disclosed for selective removal and recovery of H2S from a gaseous volume, e.g., from natural gas. Anhydrous organic, sorbents chemically capture H2S gas to form hydrosulfide salts. Regeneration of the capture solvent involves addition of an anti-solvent that releases the captured H2S gas from the capture sorbent. The capture sorbent and anti-solvent are reactivated for reuse, e.g., by simple distillation.
