Abstract (en)
[origin: WO2007020252A2] The invention relates to a method and to an arrangement for liquefying, in particular, by precooling or by supercooling, a stream which is rich in hydrocarbon, in particular a stream of natural gas, by the indirect exchange of heat with the coolant mixture of at least one coolant mixture circuit, which takes places by means of at least one heat exchanger (E). After relaxing (3), the coolant mixture is vaporised counter to the stream which is rich in hydrocarbons and which is to be liquefied and counter to itself. According to the invention, between approximately 90 % and approximately 99 %, preferably, 95 % of the stream of coolant mixture, which is to be vaporised, is vaporised, subsequently, the partially vaporised stream of coolant mixture is separated (D --> 5, 6) into a gas fraction and into a liquid fraction, the gas fraction is compressed to a desired end pressure, in particular, by means of at least one cold-suctioning (5) compressor (V), the liquid fraction is pumped, in particular, by means of at least one pump (P), and finally, the gas fraction and the liquid fraction are purified(1 and/or 2'), prior to or after, in particular, respective relaxing (3 and/or 9).
