“…Their study also revealed that amine was entrained by aerosol, which was produced from SO3. A pilot plant at Karlsruhe Institute of Technology conducted a series of aerosol studies and estimated gas-particle growth mechanism (Brachert et al, 2014;Khakharia et al, 2015;Mertens et al, 2014). Mertens et al (2014) found that the sizes of H2SO4 aerosols, with 10 8 #/cm 3 particle number concentration (PNC), entering the absorber were smaller than 0.2 μm.…”

“…They also observed that higher sulfuric acid concentration increased the aerosol size; however, it did not affect the PNC. Khakharia et al (2015) reported that amine solvents could condense on the surface of nuclei and get carried away to the atmosphere. SO3/H2SO4 nuclei formed the aerosols.…”

“…The presence of fine particles in the flue gas could be attributed to a "penetration window," which is the size range of particles that pass through the ESP, around 100 nm for traditional ESPs (Strand et al 2002;Ylätalo and Hautanen 1998;Zhuang et al 2000). Consequently, a large number of fine particles provide seed nuclei onto which volatile amine species condense, causing significant amine emissions from CO 2 scrubbers (Kamijo et al 2013;Khakharia et al 2015Khakharia et al , 2013Mertens et al 2014;2012;. A laboratory study on CO 2 capture found that when soot particles, which contain mostly carbon and result from incomplete coal combustion, were present in the flue gas, the amine emission loss was 2-4 times higher than that without fine particles present in the inlet gas (Khakharia et al 2013).…”

“…Some of these amines, such as monoethanolamine (MEA), 2-amino-2-methylpropanol (AMP) and piperazine (PZ), are known to be volatile, and therefore they can be emitted to the atmosphere together with the treated flue gas stream (Khakharia et al 2015). These amine compounds can react with other compounds in the carbon capture system and the atmosphere to form a wide range of components.…”
