Applications

The same cartridge, with a different crystal, solves different separations. These three are the current focus. Other gas separation problems are reviewed on request.

1Hydrocarbon separation

Polymer and olefin plants send valuable molecules to flare or fuel because recovering them by distillation costs too much. A membrane on the off-gas recovers them and frees capacity in the existing train.

  • Off-gas recoveryProduct back to process
  • Flare gas recoveryLess flaring
  • Debottlenecking+8% capacity cited
  • Feedstock flexibilityPer project

2Carbon capture

Point-source capture from flue gas without amine and without a steam-hungry stripper. Sized as modular units that can start with one container on one stack, as at Qemetica in Poland.

  • Point-source CO₂Cement, lime, chemicals
  • CO₂ for usee.g. carbonates on site
  • CO₂ for storagePreparation to spec
  • Capture per system25,000 t/yr cited

3Specialty gases and emission control

High-value gases where every recovered kilogram counts and every lost kilogram is an emission: refrigerants, fluorinated compounds and semiconductor process gases.

  • PFAS emission controlAbatement
  • Semiconductor gasesRecovery
  • StatusApplication development
