Chemical absorption of carbon dioxide (CO2) using amine solution is considered as the readiest technology available for capturing CO2 gas from industrial processes. The well-known amine for this process is 2-aminoethanol (MEA) which is normally mixed with water to a typical concentration of 30 wt%. MEA degrades over time producing non-reactive chemicals such as 2-oxazolidinone (OZD) due to exposure to impurities and high process temperature. It is thus important to find a suitable method for OZD qualification and quantification. In this work, we approach this challenge by means of Raman spectroscopy and multivariate data analysis. We started by collecting Raman spectra of 40 OZD samples and applying Principal omponent Analysis to study these samples.References
