Abstract: A system and method for recovering high-quality biomethane (RNG) from biogas sources is provided. The gas stream is compressed and liquids are separated from the gas stream at elevated pressure and reduced temperature. The compressing is performed using a plurality of compressors operating in parallel with common control set points. The system and method improve upon conventional practices and yield a biomethane product which meets strict gas pipeline quality specifications. Additionally, the system and method are an improvement to the overall methane recovery efficiency for biogas processing facilities.

Abstract: A stackable container includes a circular base. A body portion extends upward from the circular base. A rim section has an opening, wherein the body portion extends between the circular base and the rim section to define a container volume. The rim section includes an outwardly extending spout that is defined within an upper edge, and a ramp section that defines a linear portion of the upper edge. The linear portion of the ramp section defines a transitional interface where material on a substrate can be transported into the container volume via the ramp section resting on the substrate.

Abstract: A vent enclosure includes an adapter strap that is configured to extend around a vent member. The adapter strap has a plurality of attachment features. The adapter strap has fastening ends. The vent enclosure further includes a fastener that is attached to the fastening ends to secure the adapter strap in an encircling position, and a hood that is attached to the attachment feature of the adapter strap.

Abstract: A vent enclosure includes a mount that has a receiver that includes an enclosed volume. The mount is configured to be positioned proximate a vent aperture. A viscous material is disposed within the enclosed volume. A panel is rotationally coupled to the receiver. The panel is configured to be operable between a blocking position and an outflow position. The panel is configured to be moved to the outflow position in response to a flow of process air moving through the vent aperture. The panel returns to the blocking position under a force of gravity. The vent enclosure further includes a hinge that is attached to the panel and the receiver. The hinge engages the viscous material, and rotation of the panel and the hinge rotationally operates the hinge relative to the viscous material. The viscous material slows the rotational operation of the hinge.
