Abstract

En fremgangsmåte for kondensering av en hydrokarbonrik strøm, særlig en jordgasstrøm, hvor kondenseringen av den hydrokarbonrike strømmen skjer mot en kuldemiddelblandingskretsløpskaskade som består av tre kuldemiddelblandingskretsløp, hvor det første av de tre kuldemiddelblandingskretsløpene tjener til forkjølingen, det andre kuldemiddelblandingskretsløpet til kondenseringen og det tredje kuldemiddelblandingskretsløpet til underkjølingen av den kondenserte hydrokarbonrike strømmen. Ifølge oppfinnelsen skjer fortettingen av kuldemiddelblandingen (2c) i det tredje kuldemiddelblandingskretsløpet ved hjelp av to fortettere (V2, V2) koplet etter hverandre og med i det vesentlig samme effekt, og fortettingen av kuldemiddelblandingen (3c, 3e, 4c, 4e) i det første og det andre kuldemiddelblandingskretsløpet skjer i hvert ved hjelp av en fortetter (V4, V3) med i det vesentlige samme effekt som fortetterne (V2, V2) i det tredje kuldemiddelblandingskretsløpet. Her blir fortetterne (V4, V3) i det første og andre kuldemiddelblandingskretsløpet og fortetterne (V2, V2) i det tredje kuldemiddelblandingskretsløpet fortrinnsvis drevet ved hjelp av to drivverk som er i det vesentlige identiske og/eller har samme effekt.A process for condensing a hydrocarbon-rich stream, in particular a natural gas stream, wherein the condensing of the hydrocarbon-rich stream takes place against a refrigerant mixture cycle cascade consisting of three refrigerant mixture circuits, the first of the three refrigerant mixture circuits serving for the cold, the second refrigerant mixture and the refrigerant mixture the subcooling of the condensed hydrocarbon-rich stream. According to the invention, the densification of the refrigerant mixture (2c) in the third refrigerant mixture circuit takes place by means of two densifiers (V2, V2) connected one after the other and with substantially the same effect, and the densification of the refrigerant mixture (3c, 3e, 4c, 4e) in the first and the second refrigerant mixing circuit takes place in each by means of a densifier (V4, V3) with substantially the same power as the densifiers (V2, V2) in the third refrigerant mixing circuit. Here, the densifiers (V4, V3) in the first and second refrigerant mixture circuits and the densifiers (V2, V2) in the third refrigerant mixture circuit are preferably driven by means of two drives which are substantially identical and / or have the same effect.
