Method for Cooling or liquid Flow rich in hydrocarbons which comprises indirect Heat Exchange with the Refrigerant Refrigerant mixture (a) or (b) of mixed Refrigerant Cycle,Where (a) or (b) is subject to Compression by means of Turbo com

摘要

The invention relates to a method for cooling or liquefying a hydrocarbon-rich flow, especially a natural gas flow, by indirect heat exchange with the coolant or coolant mixture of at least one coolant (mixture) circuit, the coolant or coolant mixture being subjected to compression. The invention is characterized in that the coolant or coolant mixture is compressed by at least one single-shaft radial turbocompressor with inlet guide vanes. The one or more single-shaft radial turbocompressors with inlet guide vanes are driven by at least one electric motor and/or at least one gas turbine.
