Provide solutions for biogas upgrading and liquefaction

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.
