The TCM DA amine plant was operated with an aqueous monoethanolamine (MEA) solvent system, treating flue gas from a combined heat and power (CHP) plant. Emission monitoring was conducted by a Fourier Transform Infrared (FTIR) Spectroscopy analyzer, a Proton Transfer Reaction Time-of-Flight Mass Spectrometry (PTR-TOF- MS) analyzer, and manual isokinetic sampling followed by off-line analysis in the laboratory.

The mole fractions of the organic compounds ranged from (0.2 to 0.95) and the temperatures from (283 to 353) K. Standard state thermodynamic properties like ΔrG, were derived from the results. The basic strength of the protonated alkanolamine decreased with decreasing dielectric constant and increase in temperature of the solvent.

The alcohol mole fractions were ranging from 0.2 to 0.95 and the temperatures from 283 to 323K, 283 to 333K, and at 298.15K, respective to the different solvents. The experimental results are reported with the standard state thermodynamic properties. The basic strength of
