A natural gas system includes a process suction conduit, a compressor package configured to receive a flow of natural gas from the process suction conduit and to increase a pressure of the flow of natural gas whereby the flow of natural gas is discharged from the compressor package as a pressurized flow of natural gas, a process discharge conduit connected downstream of the compressor package, and an emissions management module coupled to the compressor package and configured to capture emissions from the compressor package, wherein the emissions management module includes a vapor recovery unit configured to circulate the captured emissions from the VRU along an emissions discharge conduit coupled to the VRU to at least one of the process suction conduit, a fuel gas system of the natural gas system, and a hydrocarbon processing component of the natural gas system that is separate from the compressor package.

A low carbon emission compression station is disclosed. The compression station is connected to a gas handling system and to an electric grid and comprises at least one electric motor driven compressor. Additionally, the compression station is connected to auxiliary energy sources and energy storage devices, comprises a supervision system, and is configured to operate in dual mode, i.e. is configured to: use power from the electric grid to compress the gas in the gas handling system and/or store energy in excess into said energy storage devices; and/or exploit auxiliary energy sources and/or stored energy to compress the gas in the gas handling system and/or also to deliver energy in excess to the electric grid.

The transportation of captured carbon from production sites to a destination at which it can be stored or used traditionally requires the carbon to be carried into a tanker truck for road transport, which is costly. Disclosed embodiments eliminate or reduce this cost by compressing the captured carbon into an existing natural gas pipeline. The existing network of pipelines can then be used to transport the captured carbon to a distant destination, while potentially picking up additional captured carbon along the way. In addition, a portion of the captured carbon at each production site may be redirected back to the engine of the compressor to enable higher power density and prevent knocking.
