摘要： A method for producing ethylene and/or other olefins by steam cracking includes charging one or more crackers with a paraffin-containing feed and withdrawing a crude gas from the one or more crackers. The crude gas is subjected at least in part to a treatment comprising a crude gas compression and a thermal separation using a C2 refrigerant and a C3 refrigerant. A crude gas compressor is used for the crude gas compression, wherein the ethylene refrigerant is compressed using a C2 refrigerant compressor. The propylene refrigerant is compressed using a C3 refrigerant compressor. The crude gas compressor comprises two serial compressor trains. The compressor trains, the C2 refrigerant compressor and the C3 refrigerant compressor are each operated at least in part using electrical drives, which have at least partially identical performance features, are provided as structurally identical variable-speed drives, and are each fed via frequency converters.
