METHOD FOR INHIBITING AMINE DEGRADATION DURING CO2 CAPTURE FROM A GAS STREAM

摘要

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.
