Abstract
Изобретение относится к способу разделения смеси (K) компонентов, которая содержит водород, метан, углеводороды, имеющие два атома углерода, и углеводороды, имеющие три или более атомов углерода, в котором при деэтанизации по меньшей мере часть смеси (K) компонентов подвергают первой частичной конденсации посредством охлаждения от первого уровня температуры до второго уровня температуры при первом уровне давления, чтобы получить первую газовую фракцию (G1) и первую жидкую фракцию (C1), по меньшей мере часть первой газовой фракции (G1) подвергают второй частичной конденсации посредством охлаждения от второго уровня температуры до третьего уровня температуры при первом уровне давления, чтобы получить вторую газовую фракцию (G4) и вторую жидкую фракцию (C2) и по меньшей мере часть первой жидкой фракции (C1) и по меньшей мере часть второй жидкой фракции (C2) подвергают ректификации, чтобы получить третью газовую фракцию (G3) и третью жидкую фракцию (C3+). Первую жидкую фракцию (C1) или ее часть, подвергаемую ректификации, и вторую жидкую фракцию (C2) или ее часть, подвергаемую ректификации, расширяют до второго уровня давления перед ректификацией и ректификацию выполняют при втором уровне давления, причем первый уровень давления составляет от 2,5 до 3,5 МПа (от 25 до 35 бар), а второй уровень давления составляет от 1,4 до 1,7 МПа (от 14 до 17 бар). Верхний поток газа, образованный при ректификации, охлаждают до температуры от -25 до -35°C и частично конденсируют, при этом конденсированную часть верхнего потока газа используют, частично или полностью, в качестве флегмы при ректификации, а несконденсированную часть верхнего потока газа поставляют, частично или полностью, в качестве третьей газовой фракции (G3). Изобретение также обеспечивает соответствующую установку (100, 200).
