Denmark Decanting Station

This facility uses digesters that convert natural animal byproducts and food waste into biogas. The client’s CH₄ pipeline injection system had extra capacity, creating an opportunity for offloading trucks of compressed CH₄ from other nearby renewable natural gas (RNG) facilities. Some of the RNG facilities in the area do not have a natural gas interconnect. This new truck unloading system allowed them to establish a “virtual pipeline.” CH₄ truck unloading requires specialized equipment to control and measure properties of gas, such as pressure, temperature, and composition. Our team identified locations in the client’s facility for system placement. We then coordinated with vendors to integrate owner-supplied equipment. We also confirmed that piping designs and equipment specifications met the system’s needs. As part of this project, our team completed process piping design and implemented tower lighting and bollards for the new equipment, so that tie-ins to existing equipment needed minimal system downtime. Our construction management services and engineering site visits provided accurate execution of the design-build. The facility is now successfully offloading 2,000 standard cubic feet per minute of RNG.
