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
