This diversified energy company wanted to create a new facility to produce renewable natural gas (RNG) and needed assistance with design, procurement, construction, installation, and commissioning. Our team faced two challenges with this project: designing the new facility to accept and treat biogas simultaneously from two separate farms and designing it in a manner that would enable the system to accept additional biogas trucked in from other RNG facilities (a potential future expansion under consideration).
We designed and installed the transfer site and central upgrading facility, biogas drying and transfer facility, and pipeline injection system. Project features included a gas compression system, two-stage membrane treatment, and other gas process skids for removal of water (H₂O), hydrogen sulfide (H₂S), carbon dioxide (CO₂), and other impurities. A pipeline transfers 480 SCFM biogas from two existing anaerobic digesters to a central processing facility, where it is upgraded to pipeline-quality standards. 275 SCFM of RNG is injected directly into a nearby utility pipeline.
