Abstract (en)
[origin: WO2009140993A1] A method for removing contaminants, such as water, CO2 and/or H2S, from a contaminated gas stream comprises inducing the gas stream to flow through a conduit (10) having a first and a second conduit section (11,12) and optionally further conduit sections (13-15), which each comprise : a) a cyclonic fluid separation section (11A-15A) in which the gas stream is induced to swirl such that contaminants ( 11B-15B) flow to an outer region of the separation section and a purified gas fraction (11C-15C) flows into a central region of the separation section; b) a central purified gas outlet tube (11D-15D) for discharging the purified gas fraction; c) an outer discharge tube (11E-15E) for discharging the contaminants; and d) a venturi section (11F-15F)in which the gas stream is accelerated and the static pressure is reduced; wherein the method further comprises: connecting the central purified gas outlet tube (12D) of the second conduit section (12) to the venturi section (HF) of the first conduit section (11) such that a purified gas fraction is induced to flow from the second conduit section (12) into the first conduit section (11); injecting a contaminants absorbent (18, lean MEG) into the venturi section (HF) of the first conduit section (11); and inducing a contaminants and contaminant absorbent enriched fluid fraction to flow via a MEG recycling conduit (19) from the outer discharge tube (HE) of the first conduit section into the venturi section (12F) of the second conduit section (12) and optionally inducing a contaminants and contaminant absorbent enriched fluid fraction to flow via further MEG recycling conduits (20,21 and 22) from the outer discharge tubes (12E-14E) of the second, third and fourth conduit sections into the venturi section (13F-15F) of the third, fourth and fifth conduit section (13-15), respectively.
