| titleOfInvention | Quaternary pyridinium salt inhibitor system for gas conditioning solutions |
| abstract | A B S T R A C T The present invention resides in the area of corrosion inhibition in gas conditioning where CO2 and small amounts of H2S are removed by an absorbent. The invention is an inhibitor composition for alkanolamine solutions and other absorbents for removing CO2 and small amounts of H2S from gas streams, comprising an inhibiting concentration in the absorbent of a combination of one part by weight of a quarternary pyridinium salt and either (1) 0.001-10 parts of a thio compound which is a water-soluble thiocyanate, a water-soluble sulfide, or an organic thioamide, or (2) 0.01-10 parts of a lower alkylene-polyamine, a corresponding polyalkylenepolyamine or mixture thereof, wherein the alkylene units contain 2-3 carbon atoms. The advantages obtained over the prior art are less corrosion than results from numerous known inhibitor combinations, and the claimed inhibitor systems are essentially non-toxic, in contrast with previous inhibitor systems using arsenic, antimony or vanadium. |
