Abstract
1. Способ сжижения потока богатого углеводородом, предпочтительно, потока, содержащего природный газ, в котором сжижаемый богатый углеводородом поток обменивается теплотой с хладагентом, при этом способ включает в себя, по меньшей мере, следующие стадии, на которых: ! (a) испаряют жидкий хладагент, используя для этого теплоту потока богатого углеводородом, с получением в результате испаренного хладагента; ! (b) сжимают испаренный хладагент с получением тем самым полностью сконденсированного сжатого хладагента; ! (c) охлаждают сжатый хладагент окружающим воздухом, за счет чего сжатый хладагент полностью конденсируется; ! (d) расширяют полностью сконденсированный сжатый хладагент с образованием в результате указанного жидкого хладагента, ! при этом перед расширением на стадии (d) полностью сконденсированный сжатый хладагент дополнительно переохлаждают за счет косвенного теплообмена с вспомогательным хладагентом, циркулирующим с осуществлением цикла вспомогательного хладагента, включающего стадию сжатия вспомогательного хладагента, за которым следует отвод теплоты от полностью сконденсированного сжатого хладагента для его дополнительного переохлаждения, ! причем вспомогательный хладагент выбирают таким, чтобы его температура кипения была выше, чем температура кипения жидкого хладагента при одинаковом давлении указанных хладагентов. ! 2. Способ по п.1, в котором дополнительное переохлаждение осуществляют до температуры, которая ниже температуры окружающей среды. ! 3. Способ по п.1, в котором вспомогательный хладагент выбирают таким, чтобы он имел теплоту испарения выше теплоты испарения жидкого хладагента. !
