Abstract

The CO₂ desorption analyses of amines were performed to reveal the behaviour of amine regeneration process. A typical primary amine (MEA) and two other secondary amines (MMEA and DEA) were selected in preparation for amine solutions under different concentrations, from 1-7 mol/L. The regeneration curves were plotted to describe the process. It was discovered that the specific CO₂ loading (mol/mol) that distinguish the amine regeneration curves into different regions were the same for the specific amine, despite different concentrations. These points were defined as "turning points" on regeneration curves. The turning points of MEA, MMEA and DEA are located at CO₂ loading of 0.40 mol/mol, 0.38 mol/mol and 0.28 mol/mol, respectively. The regeneration tests compared the relative heat duty at the first 2 hours: MMEA > MEA > > DEA.
