Biogas is a valuable renewable energy source that requires efficient upgrading before it can be fully utilized. The primary components of biogas such as methane (CH₄) and carbon dioxide (CO₂) can first be separated to unlock the energy potential of the stream. Following separation, both gases require high-level purification to meet the specifications for downstream use. A typical upgrading scheme begins with H₂S removal to protect downstream equipment and ensure process reliability. The main components, CH₄ and CO₂, are separated and purified to meet the specifications of the final application.​We provide advanced purification and upgrading solutions covering the full process chain, from pretreatment to final gas conditioning. Where required, the purified streams can be precisely adjusted to achieve a specific CO₂/CH₄ ratio, supporting applications such as methanol synthesis and other downstream conversion processes.
