Compression of biomethane to 250 bar for cascade filling
Upgraded biomethane leaves the upgrading plant at low pressure and has to be compressed before it can be stored in cascades or sent to dispensers. CRA's CBG compression packages take the gas up to 250 bar on a single skid, with the compressor, coolers, controls and safety systems engineered together and matched to the upgrading plant.

Single skid
Operation
Automatic
What does a CBG compression package do?
A CBG compression package raises upgraded biomethane from the outlet pressure of the upgrading plant to the pressure needed for cascade storage. It is the last stage of the gas train before the gas is stored or sold.
How it works
The package takes biomethane from the upgrader and delivers it to the cascades.
The package takes upgraded biomethane from the outlet of the upgrading plant.
The compressor raises the gas to cascade pressure.
Coolers bring the temperature of the compressed gas back down.
The gas fills the cascades for storage or dispatch.
The package starts, loads and stops with the plant's demand.
Key Benefits
The package compresses biomethane to 250 bar for cascade filling.
Compressor, coolers, controls and safety systems are packaged on one skid.
The package is sized to the output of the upgrading plant it follows.
The package starts, loads and stops with the plant's demand.
The package can be supplied on its own or as part of a CRA CBG gas train.

Frequently Asked Questions
What pressure does the package deliver?
The package compresses upgraded biomethane to 250 bar for cascade filling.
Can the package follow another supplier's upgrading plant?
Yes. CRA matches the package to the output and outlet conditions of the upgrading plant at site.
Is the package supplied as a skid?
Yes. The compressor, coolers, controls and safety systems are packaged on one skid.
What data does CRA need for an offer?
CRA needs the biomethane flow, its inlet pressure, the required outlet pressure and the site conditions.
Does CRA supply the metering after compression?
Yes. CRA supplies custody transfer metering skids for CBG.
