Control System
• The Plant can be started remote
• 100% selfcontained control from standby to 100% production
based on upstream biogas production
• ”Fail to safe” operation at trip (requires manual intervention
to restart)

Operational experiences
• Produced LBG on first start-up
• Cool down from warm plant: 3 hrs
• Control system automated from demo-plant
• Liquefaction system adapts to varying gas flows
• Unstable biogas produciton in digester(s)
• Too low biogas flow – lower than minimum design flow for LBG plant
• LBG produced when gas available
