Abstract

Способ разделения Суглеводородных фракций двустадийного дегидрирования н-бутана, включающий раздельное выделение из продуктов дегидрирования первой и второй стадий бутен-бутадиеновых и бутан-бутеновых фракций в колоннах ректификации с последующим разделением бутан-бутеновой фракции, выделенной из продуктов дегидрирования первой стадии, в первой колонне экстрактивной ректификации на бутановую и бутеновую фракции, а бутен-бутадиеновых фракций обеих стадий дегидрирования - во второй колонне экстрактивной ректификации на бутеновую фракцию и бутадиен, отличающийся тем, что, с целью повышения степени разделения и снижения потерь Суглеводородов, 0,95 - 10 мас.% бутеновой фракции, выделенной из бутен-бутадиеновых фракций, и 10 - 100 мас.% бутан-бутеновой фракции, выделенной из продуктов дегидрирования второй стадии, возвращают в исчерпывающую часть первой колонны экстрактивной ректификации с подачей бутеновой фракции ниже точки ввода бутан-бутеновой фракции.The method of separation of Hydrocarbon fractions of a two-stage dehydrogenation of n-butane, including separate separation from the dehydrogenation products of the first and second stages of the butene-butadiene and butane-butene fractions in rectification columns, followed by separation of the butane-butene fraction isolated from the first stage dehydrogenation products, in the first extractive column rectification for butane and butene fractions, and butene-butadiene fractions of both dehydrogenation stages - in the second column of extractive distillation for butene f stock and butadiene, characterized in that, in order to increase the degree of separation and reduce the loss of Hydrocarbons, 0.95 - 10% by weight of the butene fraction isolated from the butene-butadiene fractions, and 10 - 100% by weight of the butane-butene fraction isolated from the dehydrogenation products of the second stage, return to the exhaustive part of the first extractive distillation column with the supply of the butene fraction below the entry point of the butane-butene fraction.
