Abstract

1. Способ удаления фракции с высоким содержанием азота из исходной фракции, содержащей в основном азот и углеводороды, при котором исходную фракцию частично конденсируют и ректификационным методом разделяют на фракцию с высоким содержанием азота и фракцию с высоким содержанием метана, отличающийся тем, что во время прерывания подачи исходной фракции применяемая (применяемые) для ректификационного разделения разделительная колонна (разделительные колонны) (T1/T2), а также служащие для частичной конденсации (E1) исходной фракции и охлаждения и нагрева, образующихся при ректификационном разделении технологических потоков теплообменники (E2) посредством одной или нескольких различных охлаждающих сред (6-11) удерживаются на уровнях температуры, которые по существу соответствуют уровням температуры во время нормального режима эксплуатации разделительной колонны (разделительных колонн) (T1/T2) и теплообменников (E1, E2).2. Способ по п.1, отличающийся тем, что в качестве охлаждающей среды (6-11) применяют фракцию с высоким содержанием углеводородов, предпочтительно сжиженный природный газ (СПГ), отпарной газ, жидкий и/или газообразный азот.
