Cryogenic process
One stage liquifaction
• Very stable• Large variation of gas mixes• Handles peak loads, like high
concentration CO2 or N2• Easy startup, recovery and
process control• Load adjustment 0-100%
3 phase separation
• Post-treatment of LNG• Separates all crystals• LNG at any desirable• pressure or temperature• Under saturated LNG

Process Design
Design principles
• Fluctuating gas flow• Fluctuating gas composition• Integration of gastreatment and
liquifaction• High up-time• Easy start-up and recovery• Continue process flow • (no batch processen)• Reliable quality of LNG• Modular setup
Challanges
• Keep Capex and Opex as low as possible
• Determine allowed bandwidth of impurities and gascomposition
• Robust process line-up• Low energy usage• Low loss of methane• Re-use of CO2• LNG at any temperature or/and
pressure

Research Goals
General
• Make small scale (Bio-)LNG economically feasible
• Design and test a robust totalsystem from raw gas to LNG
• Patent validation• Get insight and grip on
crystallisation and separationof CO2
Technological
• Crystallization effects• CO2 crystal sizes• Sticky or dry• Nucleation
• Determine bandwidth of impurities anduncondesables, like N2
• Push the system to the limits

Results
Constant quality of LNG Specific energy use of 1,2 kWh/kg:
• 0,7 liquefaction• 0,5 gastreatment
Adjustable capacity 0-100% Start-up time <10 min, Steady state in < 1 hour Operational Intelligence of Osisoft Keeps running under extreme conditions, like temporary
overshoot of CO2, H2O, N2 Patent and simulation models are validated
