Abstract
1. Способ разделения углеводородов Cразной степени насыщенности путем экстрактивной ректификации с выделением в колонне экстрактивной ректификации в дистилляте фракции более насыщенных углеводородов и в кубовом продукте насыщенного экстрагента, содержащего менее насыщенные углеводороды, с последующим выделением менее насыщенных углеводородов в дистилляте десорбционной колонны и экстрагента в кубовом продукте, включающий отбор из укрепляющей части десорбционной колонны бокового парового потока, его конденсацию с получением сконденсированного углеводородного потока, испарение сконденсированного углеводородного потока с последующей подачей полученного парового потока в колонну экстрактивной ректификации, отличающийся тем, что, с целью снижения энергозатрат, из укрепляющей части десорбционной колонны дополнительно отбирают жидкий углеводородный поток в количестве, равном количеству флегмового орошения десорбционной колонны, и смешивают со сконденсированным углеводородным потоком перед подачей последнего на испарение.2. Способ по п.1, отличающийся тем, что, с целью регулирования температуры в десорбционной колонне, часть отобранного жидкого углеводородного потока в количестве 0,01 - 0,3 мас.доли возвращают в десорбционную колонну под тарелку отбора этого потока.1. A method of separating hydrocarbons of various degrees of saturation by extractive distillation, isolating the extractive distillation fraction of more saturated hydrocarbons in the distillate and a saturated extractant containing less saturated hydrocarbons in the bottom product, followed by separating less saturated hydrocarbons in the distillation column of the desorption column and extractant , including the selection of the reinforcing part of the desorption column side of the steam flow, its condensation with getting skonde nsirovannogo hydrocarbon stream, evaporation of the condensed hydrocarbon stream, followed by feeding the resulting steam stream into the extractive distillation column, characterized in that, in order to reduce energy consumption, the hydrocarbon liquid stream is additionally removed from the strengthening part of the desorption column and the reflux irrigation of the desorption column mix with the condensed hydrocarbon stream before feeding the latter to evaporation. The method according to claim 1, characterized in that, in order to control the temperature in the desorption column, part of the selected liquid hydrocarbon stream in an amount of 0.01 - 0.3% by weight is returned to the desorption column under the selection plate of this stream.
