Octavius : Establishment of guidelines and standard operating procedures (SOPs) regarding sampling and analyses for the monitoring of pollutants emitted in CCS process liquid and atmospheric matrices
Résumé
Within OCTAVIUS EU FP7 SP1 subproject, a work package has been dedicated to the promotion of guidelines for the measurement of regulated pollutants (SO2, NOx, aldehydes, CO, CO2, etc) and nitrogenous compounds (amines, nitrosamines, amides, etc) in the three matrices generated by CO2 capture processes using amine based solvents i.e atmospheric emissions, wash water liquid wastes and circulating solvent. Processes of post combustion CO2 capture using amine based solvents are indeed likely to generate, and emit, not only common pollutants, but also nitrogenous compounds whose effects on environment and human health may not be negligible. It is of primary importance to be able to measure those compounds using a reliable and accurate methodology. The guidelines have been delivered under the form of standard operating procedures (SOPs) which consist in recommendation in terms of sampling methods, samples storage, sample preparation and analyses. They are based on a review of existing standards, international literature and feedback from Octavius partners involved in such measurements, as well as evaluation tests performed on site and round robins on analytical methods.
