Abstract

Предложен способ получения олефина, имеющего N атомов углерода, в котором с использованием дегидрирования формируют технологический газ, который содержит, по меньшей мере, олефин, имеющий N атомов углерода, парафин, имеющий N атомов углерода, и углеводород, имеющий N-1 атомов углерода, и в котором с использованием по меньшей мере части технологического газа формируют входной поток сепарации, который подвергают низкотемпературной сепарации, при которой входной поток сепарации охлаждают ступенчато через множество уровней температуры, а конденсаты отделяют от входного потока сепарации, при этом конденсаты, по меньшей мере, частично подвергают первой низкотемпературной ректификации с получением первой газовой фракции и первой жидкой фракции, при этом первая газовая фракция содержит, по меньшей мере, олефин, имеющий N атомов углерода, в более низкой пропорции, чем в конденсатах, и углеводород, имеющий N-1 атомов углерода, в более высокой пропорции, чем в конденсатах. Предусмотрено, что первую газовую фракцию, по меньшей мере, частично подвергают второй низкотемпературной ректификации с использованием жидкой флегмы, содержащей преимущественно или исключительно углеводород, имеющий N-1 атомов углерода, при которой происходит обеднение первой газовой фракции олефином, имеющим N атомов углерода. Соответствующая установка (100) также является объектом изобретения.
