Green CO2 technologies at the service of the environment
Biogas upgrading releases two flows :
This “off-gas” can be processed to recover and recycle the CO2 it contains.
Arol Energy offers effective biogenic CO2 production and recovery solutions using innovative technologies which are contributing to the energy transition and the improvement of the overall facility and profitability.
The bio-CO2 produced within the upgrading
process can be liquefied and transported to
consumption sites: injection of CO2 in
agricultural greenhouses, production of dry ice,
food and chemical industries, production of
coolants, etc.
Compression and dehumidification of
the off-gas from biogas upgrading
Adsorption treatment of undesirable compounds (volatile organic compounds, sulfur
compounds, etc.)
CO2 liquefaction including the recovery of non-condensable gases, including methane
Non-condensable gases recycling within the biogas upgrading unit
Liquid CO2 storage
A technology of the future, methanation enables the production of methane from carbon dioxide and hydrogen.
Benefits of methanation :
