Abstract
A split mixed refrigerant ('MR') natural gas liquefication system, where low-pressure ('LP') and medium pressure (“MP”) MR compressors are driven by a first gas turbine and a propane compressor and a high-pressure (“HP”) MR compressor is driven by a second gas turbine, is disclosed. The split MR liquefication system is configured to adjust the characteristics of the HP MR compressor to require less power when less power is available and more power when more power is available compared to the system's design point. Such adjustments allow for shifting the balance of power between the propane compressor and the HP MR compressor to improve LNG production efficiency.
