Abstract

Настоящее изобретение обеспечивает способ получения газового потока, обедненного RSH, из потока газового сырья, содержащего природный газ, RSH и ароматические соединения, выбранные из группы, состоящей из бензола, толуола, о-ксилола, м-ксилола и п-ксилола, в диапазоне от 1 об.ч./млн. до 1 об.% в расчете на общий поток газового сырья. Указанный способ содержит стадии: (a) введения в контакт в зоне удаления ароматических соединений поток газового сырья с абсорбирующей жидкостью, содержащей физический растворитель, чтобы получить насыщенную абсорбирующую жидкость, содержащую ароматические соединения, выбранные из группы, состоящей из бензола, толуола, о-ксилола, м-ксилола и п-ксилола, и газовый поток, обедненный этими ароматическими соединениями; (b) введение в контакт в зоне удаления меркаптанов газового потока, полученного на стадии (а), с твердым адсорбентом, чтобы получить твердый адсорбент, насыщенный RSH, и газовый поток, обедненный RSH.The present invention provides a method for producing a RSH-depleted gas stream from a gas feed stream containing natural gas, RSH and aromatics selected from the group consisting of benzene, toluene, o-xylene, m-xylene and p-xylene, ranging from 1 about ppm up to 1 vol.% in the calculation of the total flow of gas raw materials. Said method comprises the steps of: (a) introducing a gas feed stream with an absorbing liquid containing a physical solvent into the contact in the zone for removing aromatic compounds in order to obtain a saturated absorbing liquid containing aromatic compounds selected from the group consisting of benzene, toluene, o-xylene , m-xylene and p-xylene, and a gas stream depleted in these aromatic compounds; (b) bringing the gas stream obtained in step a) into contact with the solid adsorbent in the removal zone of the mercaptans to obtain a solid adsorbent saturated with RSH and a gas stream depleted in RSH.
