Aerosol growth in CO2 absorption with MEA, modelling and comparison with experimental results

• New aerosol size distribution model. Prediction of development through absorber and water wash. Comparison with experimental data from pilot plant. emissions A new improved model has been developed tested against data. An e-NRTL equilibrium for MEA was extended to cover sulphuric acid containing droplets validated eboulliometer in this work. The droplet predicts without demister installed the absorber, within ± 20% demister, 30-80% measured emissions. well change NG-based coal-based exhaust. Under conditions reported work, number concentration found have a small effect on predicted because more gas-phase depletion high concentrations slower growth. effects counteract each other. With significant gas phase, are largely determined by mass transfer rate bulk liquid. initial had minor outlet distribution. significant: went up increased concentration. stronger low inlet CO 2 (NG) than increase is believed be caused overall driving force between liquid phase droplets. log-normal does not catch sizes range below 20-30nm. These hardly grow wash total emissions, these negligible impact
