Biogas liquefaction plant

Wärtsilä’s energy-efficient mixed refrigerant (MR) liquefaction technology is ideal for liquefaction of upgraded biogas and low-capacity natural gas liquefaction. Our fast-track engineering model, combined with the MR technology, result in low investment costs and short manufacturing time.

In our MR-based liquefier system, one single compressor and one aluminum plate-fin heat exchanger are the main components. A standard chiller is incorporated to improve energy efficiency and to ensure stable operation of the MR process.

    EGE Plant
    Key benefits
    • Well proven with multiple references
    • Low power consumption – low OPEX
    • Produce bioLNG of industrial quality at -160 C that can share infrastructure with (fossil) LNG
    • All components are conventional and of robust technology – reducing CAPEX
    • Designed for unmanned operation
    • Local control of bioLNG export - truck driver can load without assistance from main control room
    • Simple energy supply, only electric power source needed
    • Easy start up and shut down of all systems
    • Short delivery time
    • Plug and play philosophy, module based - relocation possible.
