“…8(d)), could indicate the emission of fly ash from coal power plant. With regard to the abundance of Ca-rich-sulfate-particles, possible sources such as cement production, surface weathering of limestone and flue-gas desulfurization can be hypothesized (Bigham et al, 2005). Moreover, due to the summer season, biogenic particles represent a relevant percentage for this sampling, if compared to the BG one.…”

The variation of aerosol properties under polluted air masses advection was studied in a semi-rural site in South Italy, by means of SEM-EDX analysis performed on particles collected on 13-stages impactor filters. Radiometric measurements, HYSPLIT back-trajectories and NAAPS maps helped to choose four measurement days of polluted air mass circulation, two of them collected in the warm season (31 July 2008, 16 September 2010) and two in the cold one (16 April 2009, 18 March 2010. Polluted aerosol characteristics were compared to those under background (BG) conditions (8 February 2011), highlighting differences in the particles chemical and morphological properties. One of the signatures of the air mass transport in the coarse fraction was the higher content of particles containing S, i.e., S-reacted, (27.5% on average) in comparison with BG conditions (1%). Two main sources of transported aerosols were identified: industrial processes and biomass burning, with fly ash, metal and S-rich particles in the first case, and K-salts and nitrate-coated Ca-bearingparticles in the second. Single particle analysis on the coarse fraction allowed large agglomerates of soot to be identified, with inclusions of silicate particles rich in Cu and Zn, Ca-S, fly ash and metals particles that are a clear indication of extensive modifications of aerosol size, chemical composition and, likely, radiative properties. In finer stages (EAD ≤ 0.94 µm) concurrent collection of organic and inorganic particles originated an agglomerate state matter mainly characterized by K and S for polluted conditions and by K only for BG.

“…Then, SO 2 gas dissolves in the water and reacts with Ca(OH) 2 to generate CaSO 3 .0.5 H 2 O. Portlandite was derived from the use of an excess adsorbent. The adsorbent calcines at that temperature to form CaO, which then reacts with SO 2 and O 2 in the flue gas to form CaSO 4 products [4], [5].…”

“…The residence time is sufficient to allow the SO 2 and other acid gases to react simultaneously with the sorbent and for the water to evaporate. The product produced from an SDA system is a dry FGD material commonly referred to as SDA material or dry FGD material [3]- [5].…”
