Development of a Novel Reclaiming Process for Degraded Formulated Solvents from Industrial Gas Processing and Purification (Master's thesis, University of Calgary, Calgary, Canada).

These amine solutions are degraded by reaction with O2, SOx, NOx, and other gas impurities to form heat stable salts and degradation products. A laboratory thermal reclaimer was designed to study the solvent separation from these degradation products and recovered solvent purity for both the singular and mixed. Industrial degraded samples were collected and processed using this facile reclaimer apparatus. A detailed analysis of the feed stream and the recovered product stream showed that this facile reclamation process can remove most of the undesirable impurities and restore the solvent to almost its original purity. These obtained technical data could be useful for scaling-up and designing of the commercial solvent reclaimers, especially for the CO2 capture plants.University of Calgary graduate students retain copyright ownership and moral rights for their thesis.
