Abstract

Изобретение относится к технике переработки попутного или природного газа, а именно к процессу низкотемпературной сепарации компонент газа. Техническим результатом, на достижение которого направлено предлагаемое изобретение, является увеличение степени очистки выходного газа. Указанный технический результат достигается тем, что в способе разделения смеси газов, включающем охлаждение смеси, расширение продуктов, получаемых из смеси, прокачивание по крайней мере части продуктов через ректификационную колонну, расширение смеси в закрученном потоке в сопле с разделением потока на поток, обогащенный компонентами тяжелее метана, и поток обедненными этими компонентами, нагрев обедненного потока за счет охлаждения продуктов, получаемых из смеси, согласно изобретению нагретый газовый поток сжимают в компрессоре, охлаждают в аппарате воздушного охлаждения, часть полученного газового продукта используют в качестве выходного продукта, другую часть дополнительно охлаждают, расширяют, продукты расширения направляют в колонну и/или смешивают с газофазными продуктами, поступающими из колонны в сопло. Кроме того, обогащенный поток или его часть используют в качестве хладоагента для охлаждения смеси или продуктов, получаемых из смеси, сжимают, охлаждают с помощью аппарата воздушного охлаждения и направляют в смесь.
