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
