Emissions measurement technology
To ensure that liquids do not reach other system parts (potential consequence: corrosion) or are released, e.g. through a smokestack (potential consequence: negative environmental impact), they have to be contained in mist eliminators in damp flue-gas purification systems (e.g. in power plants, waste burning facilities) or exhaust systems in other industrial facilities (e.g. steel plants and shipyards). The drops are made up of water, water-soluble or non-water-soluble liquids. To assess the drop emission and the effectiveness of the mist eliminators, we measure the drop emission using the "airborne impactor method".
For the "airborne impactor method" (also called the impactor measurement method), specially coated impactors with different widths are exposed vertical to the direction of the current in the medium to be tested. The drops hitting the plates leave stains on the coating. The stain analysis allows, on the one hand, conclusions to be made about the drop density distribution (i.e. how many drops fall within a specific drop diameter interval) and, on the other, about the content of free water. Drops in the range of approx. 5 µm up to several millimetres can be measured. The method is recommended in VDI 3679 Sheet 3 (wet separators, mist eliminators) from December 2001 for checking the performance guarantee.
