Abstract

A new absorber column with three measuring sections for aerosol characterization was constructed at Tiller, Norway. Sulfuric acid aerosols were introduced into a flue gas by a Topas atomizer. The flue gas came from a propane burner but was diluted with air to a CO2 composition of 4.4%. The aerosols into and out of the absorber were characterized with ELPI, CPC, and PDI for various Topas settings. The particle number concentrations measured by ELPI and CPC were comparable. The PDI could not measure particles smaller than 0.6 μm and was not suitable for characterizing the aerosols into the absorber. Out of the absorber the PDI measured a substantial number of particles larger than 0.6 μm that were not measured by the ELPI. These particles could explain the high emissions of MEA measured by the FTIR.

A new Bluefil demister was constructed and showed to be very efficient to remove aerosol particles and reduced the emissions of MEA with 97% compared to a standard knit mesh demister. The pressure drop increased with 13-20 mbar.
