DON’T WASTE THE WASTE

BIOGAS UPGRADING PLANT TOTAL SOLUTION

Membrane-based upgrading of biogas exploits the differences
in the permeabilities of gases through the membranes.
SEPURAN® Green membranes have the highest selectivity and
provide a superior technology for processing of crude biogas.

Evonik’s Multi Step Biogas Upgrading Process

Advantages of the Evonik Membrane

  • Excellent CH4/CO2 Selectivity
    compared to the other membranes

  • Low methane slip (loss) of <1%
    during upgrading

  • High methane yield of up to 99%

  • Highest energy
    efficiency

  • No additional ancillary materials
    such as water or sorbents
    (amines, glycols) are required

  • Starting and stopping of the plant
    is possible at short intervals,
    ensuring high flexibility

  • Following the upgrading process
    with membranes, the biomethane is
    already dry and satisfies the dew-point
    requirement for feeding into the grid

  • Easily Scalable
