| 摘要 |
The invention relates to a method for cooling or liquefying a hydrocarbon-rich flow, for example a natural gas flow, wherein cooling or liquefying the hydrocarbon-rich flow is carried out counter to at least one coolant circuit, counter to at least one coolant mixture circuit or counter to any combination of at least one coolant circuit and at least one coolant mixture circuit. According to the invention, the or at least one of the coolants and/or coolant mixtures, that is/are subjected to compression, are present inside the coolant circuit and/or the coolant mixture circuit in an at least partially condensed form and have, in all method states, in particular on the suction side(s) of the compressor, a molar density of at least 0.30 kmol/m3, preferably at least 0.35 kmol/m3. |
