Title (EN) METHOD FOR INHIBITING AMINE DEGRADATION DURING CO2 CAPTURE FROM A GAS STREAM
(FR) PROCÉDÉ D'INHIBITION DE LA DÉGRADATION DES AMINES LORS DE LA CAPTURE DE CO2 DANS UN FLUX GAZEUX
Abstract: front page image
(EN)The present application includes a method for inhibiting amine degradation during CO2 capture from flue gas streams. Particularly, the present disclosure relates to a method of inhibiting O2- and/or SO2-induced degradation of amines using sodium sulfite (Na2SO3), potassium sodium tartrate tetrahydrate (KNaC4H4O6•4H2O), ethylenediaminetetraacetic acid (EDTA) or hydroxylamine (NH2OH), or analogs or mixtures thereof during CO2 capture by amines.
(FR)Cette invention se rapporte à un procédé d'inhibition de la dégradation des amines lors de la capture de CO2 dans des flux de gaz de combustion. L'invention concerne en particulier un procédé d'inhibition de la dégradation des amines induite par O2- et/ou SO2 utilisant du sulfite de sodium (Na2SO3), du tartrate de sodium et de potassium tétrahydraté (KNaC4H4O6•4H2O), de l'acide éthylène diamine tétra acétique (EDTA) ou de l'hydroxylamine (NH2OH), ou analogues, ou leurs mélanges lors de la capture de CO2 par les amines.
