Wärtsilä Gas Solutions’ PuregasCA Technology recovers over 99.9% of the biomethane present in raw biogas by separating CO2 from the biogas through chemical adsorption.
The selective organic solvents used are so efficient that the product gas also is highly suitable for direct injection into the gas grid without any enrichments. Together with the low need for gas pre-treatment, high availability and lowest power consumption the PuregasCA Technology provides plant owners higher project profitability. It’s even possible to capture the CO2 from the plant for industrial or food purposes, increasing revenue further.
Wärtsilä Gas Solutions' biogas upgrading plants are based on the PuregasCA technology, an amine scrubber optimised for biogas and small-scale natural gas polishing.
