Abstract

Изобретение относится к способу (100) извлечения продукта разделения, который содержит преимущественно углеводороды с двумя атомами углерода, с использованием сырья для разделения, которое содержит преимущественно метан, водород и углеводороды с двумя атомами углерода, где содержание метана в сырье для разделения составляет вплоть до 20% и сырье для разделения предоставляют в газовом состоянии. Обеспечивают, что при первом уровне давления сырье для разделения частично конденсируют за одну стадию путем охлаждения от первого уровня температуры до второго уровня температуры с получением таким образом точно одной первой жидкой фракции и точно одной первой газовой фракции; по меньшей мере одну часть первой газовой фракции частично конденсируют за одну стадию посредством дополнительного охлаждения от второго уровня температуры до третьего уровня температуры с получением таким образом точно одной второй жидкой фракции и точно одной второй газовой фракции; по меньшей мере одну часть второй газовой фракции при втором уровне давления подвергают противоточной абсорбции в противотоке к абсорбционной жидкости, содержащей преимущественно метан, с получением таким образом точно одной третьей жидкой фракции и точно одной третьей газовой фракции; первую, вторую и третью жидкие фракции, по меньшей мере, частично объединяют и, по меньшей мере, частично при втором уровне давления, которое выше первого уровня давления, подвергают низкотемпературной ректификации с получением таким образом жидкости отстойника и верхнего газа; по меньшей мере одну часть верхнего газа при втором уровне давления частично конденсируют за одну стадию посредством дополнительного охлаждения от второго уровня температуры до третьего уровня температуры с получением таким образом четвертой жидкой фракции и четвертой газовой фракции; и абсорбционную жидкость, содержащую преимущественно метан, образуют посредством дополнительного охлаждения по меньшей мере части четвертой газовой фракции до четвертого уровня температуры. Объект изобретения также образует соответствующая установка.
