POWER BALANCING IN LIQUEFICATION SPLIT SYSTEM WITH MIXED REFRIGERANT Russian patent published in 2022 - IPC F25B5/00 F25J1/02 

FIELD: heat engineering.

SUBSTANCE: invention relates to the field of heat engineering; it can be used in split systems of natural gas liquefication with a mixed refrigerant. A split system of natural gas liquefication with a mixed refrigerant (hereinafter – “MR”) is disclosed, in which MR compressors of low pressure (hereinafter – “LP”) and medium pressure (hereinafter – “MP”) are actuated with the first gas turbine, and a propane compressor and MR compressor of high pressure (hereinafter – “HP”) are actuated with the second gas turbine. The liquefication split system MR is made with the possibility of adjustment parameters of MR HP compressor in such a way that to reduce power consumption, when less power is available, and to increase power consumption, when more power is available compared to a system project point.

EFFECT: providing a shift of power balance between the propane compressor and MR HP compressor to increase the efficiency of LNG production.
