Abstract

Способ получения нейтрализованного потока текучей среды из потока текучей среды, содержащего метанол и по меньшей мере один кислотный газ, включающий a) этап абсорбции, при котором поток текучей среды соединяют с абсорбентом в абсорбере, причем получают загруженный метанолом и кислотными газами абсорбент и, по меньшей мере, частично нейтрализованный поток текучей среды; b) этап регенерации, при котором по меньшей мере часть полученного на этапе a) загруженного абсорбента регенерируют в регенераторе с получением, по меньшей мере, частично регенерированного абсорбента и газообразного потока, содержащего метанол и по меньшей мере один кислотный газ; c) этап рециркуляции, при котором по меньшей мере один частичный поток регенерированного абсорбента из этапа b) возвращают на этап абсорбции a); d) этап конденсации, при котором конденсат, содержащий метанол, переконденсируют из газообразного потока из этапа b); отличающийся тем, что регенератор дополнительно содержит секцию обратной промывки, а конденсат из этапа d) частично возвращают в регенератор в верхнюю часть зоны обратной промывки или выше зоны обратной промывки.A method of obtaining a neutralized fluid stream from a fluid stream containing methanol and at least one acidic gas, comprising a) an absorption step, in which the fluid stream is combined with an absorbent in an absorber, and an absorbent loaded with methanol and acid gases is obtained and at least least partially neutralized fluid flow; b) a regeneration step, in which at least part of the loaded absorbent obtained in step a) is regenerated in a regenerator to obtain at least partially regenerated absorbent and a gaseous stream containing methanol and at least one acid gas; c) a recirculation step in which at least one partial stream of regenerated absorbent from step b) is returned to the absorption step a); d) a condensation step in which a condensate containing methanol is recondensed from the gaseous stream from step b); characterized in that the regenerator further comprises a backwash section, and the condensate from step d) is partially returned to the regenerator in the upper part of the backwash zone or above the backwash zone.
