dc.description.abstract | Post-combustion CO2 capture (PCC) with amines is the most mature technology for CO2 capture,
and is considered to be an important part of future carbon capture and storage projects.
A dynamic model of a PCC amine plant could provide useful information about the dynamic
behaviour of the plant and be used for optimization purposes. Several dynamic models of PCC
amine pilot plant exist but only few have been validated with experimental dynamic data.
In this thesis, a dynamic model of the PCC amine pilot plant at Technology Centre Mongstad
has been validated against both steady state and dynamic experimental data from Aker Solutions
test campaign. The flue gas used in the test was from a combined heat and power plant
and contained approximately 3.5% CO2. Monoethanolamine (MEA) was used as solvent and
tests with both 30 and 40 weight percent MEA were conducted.
The model was first validated against data from 8 steady state periods. Two different correlations
for mass transfer were compared (Billet and Rocha) and the model results are nearly
identical with the use of the two. The model well predicts the CO2 production rate and the
deviations between simulated and experimental results are below 8% in all the steady state periods. Some differences in temperature results are seen, especially between experimental and simulated desorber temperature profiles.
Four dynamic cases were simulated, all containing multiple parameter changes. The dynamic
cases include operations with both 30 and 40 weight percent MEA, and step-changes in solvent
flow rate and flue gas inlet were simulated. The model well predicts the dynamic responses in
all the investigated parameters. Some stationary deviations are seen, and these are assumed to be caused by errors in pilot plant data and model correlations that are used in calculations of CO2 mass transfer and hydraulic area. | en |
