Product Description

Evonik SEPURAN Green for efficient biogas upgrading

Evonik SEPURAN Green
 

Evonik has developed a biogas upgrading process that makes best use of the membranes’ separation properties: Through skillful connection of SEPURAN® Green membranes it is possible to obtain methane with a purity level of up to 99% from the crude gas. Just one compressor is needed.

SEPURAN® Green membranes have the highest CO2/CH4 selectivity and are therefore a superior technology for upgrading biogas. This selectivity of the membranes enables the production of high purity biomethane with superior methane recovery. This distinguishes the Evonik membranes from other membranes that are available.

Biogas comes from the biogas plant as a mixture of CO2, methane and the typical secondary components, and is first desulfurized, filtered and pre-dried with activated carbon. The pre-treated gas is then compressed to 10 – 20 bar, and upgraded to biomethane and a CO2-rich waste gas flow using several membrane stages.

 

The process

In addition to the SEPURAN® Green membranes, Evonik has also developed a biogas upgrading process that makes optimum use of the membranes’ separation properties: Through skillful connection of SEPURAN® Green membranes it is possible to obtain methane with a purity level of up to 99% from the crude gas with one compression step.
