LP Cooab Biogasupgrading
Biogas Upgrading Technology Based on Amine Technology
In 2001 we developed the innovative LP Cooab® (Low Pressure CO₂ Absorption) technology based on low-pressure reversible chemical absorption of CO₂. The CO₂ is absorbed in an amine based liquid in an absorber column and is regenerated by adding heat in a stripping column. The special amine composition, with our trade name Cooab® is an essential element in this process.
The heat required for the regeneration can be recovered almost 100% for heat re-use, for instance for heating of the fermenter. LP Cooab® has the lowest methane emission of all available techniques, which makes it the most sustainable system for biogas upgrading as methane causes a more than 21 times higher effect on global warming than CO₂. Because the process operates at almost atmospheric pressure, electricity consumption is also the lowest of the available technologies. With the LP Cooab technology it is possible to reduce the CO₂ level down to ppm level required for liquefaction.
