Изобретение относитс к способам разделени газовых смесей, в частности к отбензиниванию, очистке и разделению углеводородных газов, и может быть использовано в процессе подготовки природного газа к дальнему- транспорту и при стабилизации газовых конденсатов.The invention relates to methods for separating gas mixtures, in particular, to stripping, cleaning and separating hydrocarbon gases, and can be used in the process of preparing natural gas for long-haul transport and in stabilizing gas condensates.
Абсорбционные способы разделени газов включают обычно контактирование газовой смеси дл абсорбции целевых компонентов, отпарку нецелевы компонентов, абсорбированных вследствие недостаточной селективности абсорбента l .Absorption methods for gas separation usually include contacting the gas mixture to absorb target components, stripping non-target components absorbed due to insufficient selectivity of the absorbent I.
Известен абсорбционный способ раделени газовых смесей, осуществл емый в двух аппаратах: в первом - абсорбци тощим абсорбентом, во втором - отпарка нецелевых компонентов Аппараты работают при разных давлени х , схема металлоемка, способ не обеспечивает достаточно высокой степени извлечени целевых компонентовA known absorption method for separating gas mixtures is carried out in two apparatuses: in the first - by absorption with a lean absorbent, in the second - stripping of non-target components.

Наиболее близким к описываемому изобретению по технической сущности и достигаемому результату вл етс способ разделени газовой смеси методом фракционирующей абсорбции сThe closest to the described invention to the technical essence and the achieved result is the method of separation of the gas mixture by the method of fractional absorption with
использованием колонны, включающей абсорбционную и отпарную части, в среднее сечение аппарата ввод т сырой газ, тощий абсорбент подают вьниеusing a column that includes the absorption and stripping parts, the raw gas is introduced into the middle section of the apparatus, the lean absorbent is fed to
ввода сырого газа, а отпарку нецелевых компонентов из насыщенного абсорбента производ т в нижней части аппарата з.the entry of raw gas, and the stripping of non-target components from the saturated absorbent is performed in the lower part of the apparatus.
Осуществление этого способа св зано с повышенным удельным расходом абсорбента.The implementation of this method is associated with an increased specific consumption of the absorbent.
Целью изобретени вл етс снижение расхода абсорбента.The aim of the invention is to reduce the consumption of absorbent.
Поставленна цель достигаетс методом фракционирующей абсорбции с использованием колонны, включающей абсорбционную и отпарную части, заключающимс в контактировании исходной смеси с потоком тощего абсорбента , вводимого в абсорбционную часть колонны, причем ввод т дополнительный поток тощего абсорбента в отпарную часть колонны, вывод т насьиенный абсорбент из абсорбционной части колонны и ввод т его в промежуточное сечение отпарноЯ части колонны.The goal is achieved by fractional absorption using a column that includes the absorption and stripping parts, which consists in contacting the initial mixture with a stream of lean absorbent introduced into the absorption part of the column, and an additional stream of lean absorbent is introduced into the stripping part of the column. parts of the column and enter it into the intermediate section of the stripping part of the column.
