Description

Процесёь экстракции широко Ьрймён ютёй fe технологии выделени  ароматических углеводородов Из углеводородного сЬ1рь  и особенно из бензи(шлигроиио8ых фракций иефти, из катализатов риформинга,The extraction process is widely carried out with the use of fe technology for the separation of aromatic hydrocarbons from hydrocarbons and, especially, from benzium (slurry fractions and oil, from reforming catalysates,

На большинстве действующих установок по Экстракции ароматических углеводородов в качестве экстрагентов используют ди- и триэтИлёнгликоли в чиСтом виде с добавками водЫ.Most of the existing plants for the extraction of aromatic hydrocarbons use di- and triethyl glycols in the pure state with water additives as extractants.

При исследовании экстракционных свойств дйэтилепгликол  в равновесных услови х вы снилось , что даже при больпюм соотношении &кСтрагента к сырью (11:1) получают диЗтиленГликоль сравнительно невысокой концентрацией ароматических углеводородов в Экстракте.In the study of the extraction properties of diethylene glycol in equilibrium conditions, it was found that even with a large ratio of &

С целью расширени  ассортимента растворителей и увеличени  степени извлечени , предложено в качестве экстрагента с более высокими технологическими показател ми использовать метанол-глицериновую смесь, содержащую глицерин в количестве 30- 80 вес. %.In order to expand the range of solvents and increase the degree of extraction, it was proposed to use a methanol-glycerin mixture containing glycerin in an amount of 30 to 80 weight as an extractant with higher technological indicators. %

Исследование в равновесных услови х дает следующие показатели: соотнощение экстрагента к сырью равно 5:1, концентраци  ароматических углеводородов в экстракте 81%, избирательность 25 и извлечение 50%.Under these conditions, the concentration of aromatic hydrocarbons in the extract is 92.3-93.6 wt. % at a selectivity of 25.3 and a percent recovery of 40% diethylene glycol. The study in equilibrium conditions gives the following indicators: the ratio of the extractant to the raw material is 5: 1, the concentration of aromatic hydrocarbons in the extract is 81%, the selectivity is 25 and the recovery is 50%.
