| 摘要 |
The invention relates to a method for liquefying a gas (primary gas) which is part of a gas mixture that contains at least one second gas (secondary gas). Said second gas has a higher liquefaction temperature than the first gas. The gas mixture is especially cooled down by means of a heat exchanger. The second gas is subjected to phase transition at a separation temperature at which the first gas is gaseous and the second gas is liquid and/or solid, or at which the first gas is gaseous or liquid and the second gas is solid. The heat exchanger cools down the gas mixture to a temperature that lies above the separation temperature. Downstream of the heat exchanger a throttle element is disposed through which the gas mixture flows and is cooled down to the separation temperature. |
