Abstract

Способ и устройство для сжижения природного газа, имеющего избыточное давление выше 56,2 кгс/см, в которых природный газ вводят в детандер, который действует для снижения давления природного газа и извлечения работы от расширения природного газа в процессе снижения давления так, что полученный вытекающий из детандера поток может быть охлажден до последовательно более низких температур путем пропускания газа через множество охлаждающих этапов за счет косвенного теплообмена с по крайней мере одним хладагентом до тех пор, пока газ, по существу, полностью сконденсируется в последнем охлаждающем этапе.
