Abstract

Es wird ein Verfahren zum Verflüssigen eines Kohlenwasserstoff-reichen Stromes, insbesondere eines Erdgasstromes, wobei die Verflüssigung des Kohlenwasserstoffreichen Stromes gegen eine aus drei Kältekreisläufen bestehende Kaskade erfolgt und wobei der erste Kältekreislauf der Vorkühlung, der zweite Kältekreislauf der Verflüssigung und der dritte Kreislauf der Unterkühlung des Kohlenwasserstoff-reichen Stromes dient, beschrieben. Erfindungsgemäß weist das Kältemittel des der Vorkühlung (E1) dienenden Kältekreislaufes (a - a'') C3H8, C3H6, C2H6 oder C2H4 in einer Konzentration von wenigstens 95 Vol.-% auf und die Temperaturdifferenz zwischen Siede- und Taupunkt des Kältemittels beträgt weniger als 5 °C.
