ABSTRACT

Densities, viscosities, refractive indices and electrical conductivities of both artificial degraded and industrial degraded MEA solutions are measured at standard temperature of 298.15 K or 293.15 K. These physical properties measurement data are not currently available for the degraded MEA solutions and the reported values are particularly important for monitoring solvent quality and plant performance. The data can be used to provide an estimation of the total degradation products build-up level in the solvent with a simple measurement by the CO2 plant operators, which would avoid using complex equipment and lengthy laboratory techniques. The data could also be useful for the CO2 capture plant designers to consider the impact of degradation products on the physical properties of the solvent.
