Abstract
The blend MEA/MDEA (5/25%wt.) was studied on the LEMEDES-CO2 lab-scale pilot plant, with representative conditions of post-combustion CO2 capture for power generation during 900 h. CO2 loadings were determined and showed average values of 0.12 and 0.40 respectively for the lean and rich solvents. Stability of the two amines, namely MEA and MDEA, was monitored using ionic chromatography; results did not show any significant degradation of MDEA during the campaign, in contrary to MEA which showed a significant degradation in the range of 0.03 points per day. Analytical methods involving GC–MS and IC were developed in order to identify potential degradation products in the liquid phase of the solvent. Study of the gaseous emissions’ composition was also realized using sampling on different solid sorbents followed by thermal desorption and GC–MS analysis. A total of 22 compounds were listed including amines, organic acids, and pyrazines derivatives. 12 degradation products were found in the solvent itself and 11 in the treated flue gas among which MDEA, the constituent amine of the blend. A quantitative monitoring was carried out for formic and oxalic acids. Results showed concentrations reaching 500 mg/L for oxalic acid and 1400 mg/L for formic acid.
