Abstract

Способ извлечения загрязнений, таких как вода, СОи/или HS, из потока загрязненного газа, который включает индуцирование течения потока газа по каналу (10), который содержит первый и второй участки (11, 12) и необязательно другие участки (13-15) канала, при этом каждый участок содержит а) участок (11А-15А) циклонного разделения текучих сред, в котором поток газа завихряют так, что загрязнения (11В-15В) текут во внешнюю область участка разделения, а фракция (11С-15С) очищенного газа течет в центральную область участка разделения; б) центральную выпускную трубку (11D-15D) для очищенного газа, предназначенную для выпуска фракции очищенного газа; в) внешнюю выпускную трубку (11Е-15Е), предназначенную для выпуска загрязнений; и г) участок (11F-15F) Вентури, в котором поток газа ускоряют и уменьшают статическое давление; причем указанный способ дополнительно включает в себя следующие операции: соединяют центральную выпускную трубку (12D) второго участка (12) канала с участком (11F) Вентури первого участка (11) канала так, что фракция очищенного газа течет из второго участка (12) канала в первый участок (11) канала; впрыскивают абсорбент (18, регенерированный МЭГ) загрязнений в участок (11F) Вентури первого участка (11) канала и вынуждают фракцию текучей среды с повышенным содержанием загрязнений и абсорбента загрязнений течь через канал (19) рециркуляции МЭГ из внешней выпускной трубки (11Е) первого участка канала в участок (12F) Вентури второго участка (12) канала; и, возможно, вынуждают фракцию текучей среды с повышенным содержанием загрязнений и абсорбента загрязнений течь через каналы (20, 21 и 22) рециркуляции МЭГ из внешних выпускных трубок (12Е-14Е) второго, третьего и четвертого участков канала в участок (13F-15F) Вентури третьего, четвертого и пятого участков (13-15) канала соответственно.A method for extracting contaminants, such as water, CO and / or HS, from a polluted gas stream, which includes inducing a gas flow through a channel (10), which contains the first and second sections (11, 12) and optionally other sections (13-15) channel, each section contains a) a section (11A-15A) for cyclonic separation of fluids, in which the gas flow is swirled so that impurities (11B-15B) flow into the outer region of the separation section, and the fraction (11C-15C) of the purified gas flows into the central region of the separation site; b) a central purified gas outlet (11D-15D) for discharging the purified gas fraction; c) an external outlet pipe (11E-15E) designed for the release of contaminants; and d) a Venturi section (11F-15F) in which the gas flow is accelerated and the static pressure is reduced; wherein said method further includes the following steps: connect the central outlet pipe (12D) of the second channel section (12) to the Venturi section (11F) of the first channel section (11) so that a fraction of the cleaned gas flows from the second channel section (12) to the first section (11) of the channel; inject the absorbent (18, regenerated MEG) of impurities into the Venturi section (11F) of the first section (11) of the channel and force the fraction of the fluid with the increased content of impurities and the absorbent of impurities to flow through the channel (19) of the MEG recirculation from the outer outlet pipe (11E) of the first section the channel to the Venturi section (12F) of the second channel section (12); and possibly forcing a fraction of the fluid with an increased content of impurities and absorbent impurities to flow through the channels (20, 21 and 22) of the MEG recirculation from the outer outlet pipes (12E-14E) of the second, third and fourth sections of the channel to the section (13F-15F) Venturi of the third, fourth and fifth sections (13-15) of the channel, respectively.
