The present invention relates to a natural gas liquefaction process comprising at least two nitrogen refrigerant stream. Each of the nitrogen stream is expanded in each stream while the other pressure as the rest of the at least two nitrogen stream undergoing a cycle of compression, cooling, expansion and heating, the heat is generated in the at least one heat exchanger. The expanded nitrogen streams are in heat exchange relationship between at least the one or more compressed nitrogen stream and the stream of the natural gas in one of said at least one heat exchanger. At least one of the expanded nitrogen stream is compressed by a side stream in the main stage of the nitrogen compressor to the combination since the nitrogen compressor stage, other compressed nitrogen stream and the compressed side stream.
