Beschreibung
Zusammenfassung:	The invention relates to a method for cooling a hydrocarbon-rich fraction, in particular of natural gas, wherein the hydrocarbon-rich fraction (1) is cooled against at least one refrigerant circuit (10 - 15), the refrigerant includes at least nitrogen, carbon dioxide, methane and/or C2+-hydrocarbons, the compression of the refrigerant is carried out by at least one turbo compressor (C1) having one or more gas-lubricated sliding-ring seals, and the turbo compressor (C1) is supplied with a partial stream of the refrigerant and/or an external gas or gas mixture, substantially having nitrogen and/or methane, as primary barrier gas, and nitrogen is supplied as secondary barrier gas. According to the invention, at least one nitrogen-rich stream (21) is removed from the refrigerant circuit (10 - 15), at least temporarily.
