Oxidative stability of primary amines-structure-property relationship

Abstract

The area of carbon capture solvent degradation with degradation mechanisms is described in this project. Analyses of degraded samples originate from a pilot plant for carbon capture studied and a theoretically chromatographic procedure assessed with respect to the sample analyses. A Dionex DX _500 cation-exchange chromatograph with Dionex IonPac SCS 1 column is used for analysis the samples. The eluent used in this work was 8 mM MSA with 7 % (v/v) ACN. The main part was to prepare a calibration curve for MEA and show the quality of the calibration curve by calculates the standard deviation. The result shows highest value for standard deviation equal to ±34.187 % and the lowest ±8.346% for 3 mM/l and 0.5 mM/l MEA respectively. Determination coefficient for calibration curve was 0.9996 with 0.04 % deviation from the perfect fit. Some of the systematic errors in the preparation of calibration curve are quantified. The calibration curve is used to identify the remaining MEA in the oxidative degradation samples. The analysis of oxidative degraded samples was restricted to MAE and still there are a number of unknown components in the samples.
