Atmospheric degradation of amines

The overall objective is to contribute to the understanding of the atmospheric degradation of amines emitted to the atmosphere from CO₂-capture plants.

The specific objectives are: (1) To use the EUPHORE outdoor photochemical chamber to identify the gas phase photo-oxidation products resulting from amines under natural atmospheric conditions, and to quantify the main products in the gas phase photo-oxidation of amines. (2) To use the Oslo and Innsbruck photochemical chambers to obtain information on the kinetics of the OH reaction with primary products and information on secondary products of the amine photo-oxidation. (3) To verify/update/develop atmospheric photo-oxidation schemes for amines to account for all products formed under natural conditions, and to develop gas phase chemistry models for implementation in dispersion models. (4) To characterize the aerosol formed during the atmospheric photo-oxidation of amines. (5) To identify possible toxic constituents in the aerosol.
