Biogas Upgrading and CBG Gas Train

• CG-250 – three-stage membrane train for 250 Nm³/h of raw biogas.
• CG-500 – 500 Nm³/h of raw biogas, producing about 5–5.5 tonnes of CBG a day.
• CG-1000 – 1,000 Nm³/h of raw biogas, housed in two containers.

• Raw biogas feed: 250, 500 or 1,000 Nm³/h, or to client specification
• Separation: three-stage hollow-fibre membranes
• Product gas: vehicle-grade methane, with quality to the applicable fuel standard or client specification
• Discharge pressure: up to 250 bar
• CBG output: about 5–5.5 tonnes a day on the CG-500, with other sizes in proportion to the feed
• Off-gas: CO2-rich stream to vent, thermal oxidiser or CO2 recovery, to client specification
• Housing: skid or container, with the CG-1000 in two containers
• Controls: PLC and SCADA with online analyser and automatic shut-off

The train suits biogas plants that sell CBG as vehicle fuel or into city gas networks. Feedstocks include agricultural residue, cattle dung, press mud from sugar mills, distillery and dairy effluent, and municipal and food waste. With suitable pre-treatment, the same train also upgrades landfill gas.

• Low methane loss – three membrane stages lose less methane than one- or two-stage designs.
• No water or solvent – membrane separation runs dry, with no scrubbing liquid to treat.
• Standard sizes – 250, 500 and 1,000 Nm³/h trains on a common design.
• Compression included – raw biogas in, CBG out at 250 bar.
• Containerised – factory-tested modules cut site work.
• Monitoring built in – online analyser, SCADA and automatic shut-off from start-up.

• Established manufacturer – part of the Davey Group since 1990, exporting to more than 110 countries.
• Everything under one roof – in-house mechanical fabrication, electrical works, PLC and SCADA automation, and R&D.
