The efficiency challenge

Small is beautiful – The MiniLNG conceptConference ”The potential of bio-energy for future energy supply”, 5. June, 2008, Leipzig, Germany

The efficiency challenge

< 0.6 kWh/kg of LNG produced< 0.5 kWh/kg of LNG produces, if using

CO2 pre-cooling provided byDGE’s BCM-technology

Small is beautiful – The MiniLNG conceptConference ”The potential of bio-energy for future energy supply”, 5. June, 2008, Leipzig, Germany

The engineering challenge

Oil-flooded screw compressor, after-cooler, off-the-shelf heat exchangers, and expansion valves to the liquefaction system

Creation of multiple phase-changes within the heat exchangers; descending the temperature of the mixture to produce LNG

Small is beautiful – The MiniLNG conceptConference ”The potential of bio-energy for future energy supply”, 5. June, 2008, Leipzig, Germany

The engineering challenge

For a non-disruptive production of LNG the MiniLNGTM plants will be powered by a gas engine with feed gas or regeneration gas, or both.

”Plug and play” design philosophyRelocation possible

The MiniLNGTM biogas-LNG pilot plant

Full scale demonstration of the SINTEF MCR liquefaction technologyi.e. 6 or 15 tons/day – 2400 or 6000 tons/year

An LNG liquefier cannot be used without credible solutions for:Pre-treatmentTail-gas handlingPower supply

The pilot should ideally be representative with respect to:Capacity (6, or 15 tons/day)Feed gas compositionFeed gas impuritiesFeed gas pressurePre-treatment systemTail gas handlingPower generation

Proposal for fulfillment of representativeness criteria:Capacity (6 or 15 tons/day).

Paramount, impacts of scale are important

Feed gas composition.Bio gas

Feed gas impurities/Pre-treatment systemRemoval of CO2, water and traces of H2S using DGE’s BCM technology.Excessive H2S and CO2 in feed will require expensive pre-treatment.Within certain narrow limits, pre-treatment can be made fairly simple.

Feed gas pressureAll other sources than pipeline gas needs pre-compression. It is not considered necessary to

demonstrate compression, but pilot will not be built for taking advantage of cold from throttling.

Tail gas handlingA MiniLNG plant in the field should be capable of island-mode operation. All tail-gas should therefore

be treated properly by the pilot plant.

Power generationIsland-mode is required in the field. Pilot must therefore be capable of operation without being

connected to the grid. Requires UPS for control system and small auxiliary manually activated (gasoline) generator. (2,2 kW).
