Abstract

Способ разделения Суглеводородных фракций двустадийного дегидрирования н-бутана, включающий выделение из бутан-бутен-бутадиеновой фракции первой стадии дегидрирования путем ректификации в качестве кубового продукта бутан-бутеновой фракции, которую направляют на разделение в колонну экстрактивной ректификации, а в качестве дистиллята бутен-бутадиеновой фракции, из которой совместно с бутен-бутадиеновой фракцией второй стадии дегидрирования путем экстрактивной ректификации выделяют бутеновую фракцию и бутадиен, отличающийся тем, что, с целью снижения потерь бутадиена на стадии дегидрирования, бутеновую фракцию в количестве 2,5 - 30 мас.% возвращают в исчерпывающую часть колонны экстрактивной ректификации бутан-бутеновой фракции.The method of separation of the hydrocarbon fractions of the two-stage dehydrogenation of n-butane, including the separation from the butane-butene-butadiene fraction of the first stage of dehydrogenation by distillation as the bottom product of the butane-butene fraction, which is sent for separation in the extractive distillation column, and butene-butadiene form as distillate , from which, together with the butene-butadiene fraction of the second stage of dehydrogenation, the butene fraction and butadiene are separated by extractive distillation, characterized in that then, in order to reduce the loss of butadiene at the dehydrogenation stage, the butene fraction in the amount of 2.5–30 wt.% is returned to the exhaustive part of the extractive distillation column of the butane-butene fraction.
