Membrane technology

Performance, robustness and ease of operation

Arol Energy offers two complementary products according to project sizing: the AE-COMPACT and the AE-MEMBRANE. These solutions are designed to maximize biomethane productivity, equipment durability, process reliability and robustness, whilst guaranteeing ease and safety of operation.

Principle of membrane technology

  • Dehumidification and desulfurization of the
    biogas before the membranes
  • Compression of the biogas to the working pressure of the membranes
  • Separation of the CH4 and the CO2 using selective gas permeation membranes.
