Our patented Mixed Fluid Cascade (MFC
) process, jointly developed with Statoil for base load LNG plants, is designed for highest efficiency and reliability in any environment and climate.
process features three independent refrigeration cycles. The intermediate liquefaction cycle and the coldest (sub-cooling) cycle always use mixed refrigerants, while the warmest (pre-cooling) cycle can vary its refrigerant depending on the ambient temperature. MFC
stands for propane pre-cooling, with load balancing between the three refrigeration cycles so the shaft power of all three compressor trains is identical. This unique configuration enables the largest LNG capacities with a given set of main compressor drives.
In a moderate or cold climate, propane pre-cooling and perfect load balancing across the three refrigeration cycles is no longer feasible. Under these circumstances, the 'arctic' version of our MFC
process – as implemented in Hammerfest, Norway – with three mixed refrigerant cycles is the preferred solution.
