Overview
CRA’s Biogas Upgrading System refines raw biogas into high-purity biomethane (RNG) using advanced multi-stage membrane technology. With in-house expertise in H₂S scrubbing (chemical & biological) and compression, our systems deliver a methane concentration of over 98%. Designed to be compact, modular, and low-maintenance, they ensure efficient and sustainable operation for grid injection, transportation fuel, or industrial use.
