Structurally the mist eliminators consist of two coaxial cylindrical meshes welded to bottom and inlet flange branch. Frame material: stainless steel AISI 316L. The area between meshes is filled with fiber, the element bottom is equipped with a tube merged into water seal barrel out of which the trapped liquid flows to the unit case. Mist eliminators are attached to the base plate of the column through P.T.F.E. laying with the help of pins and nuts. From 1 to 50-70 elements may be arranged within one apparatus case depending on the unit performance capability. In existing sulfuric acid plants such elements are often installed in a separate case, and in new shops – in upper part of absorbers (with performance capability of up to 170 thousand м3/ч).
Reduce or eliminate visible chimney plumes.
Design capacity can be adjusted without limit.
Guaranteed pressure drop is less than 40mm (1.5”) W.G..
Interchangeable with existing fiber mat equipment.
Capture sub-micron fog particles with diameters less than 0.1 microns or less
- low-velocity (ʊ ≤ 0,2 m/sec), equipped with fibers 5-20 mcm in diameter and intended for trapping of submicron particles with the help of Browning diffusion and catching effect; their efficiency increases as the filtration velocity, particles size and fiber diameter decrease;
- high-velocity (ʊ ≤ 0,5 + 1,2 m/sec) with the layer of coarse fibers 20-100 mcm in diameter that are used for separation of gas from particles 1 mcm and larger using the mechanism of inertial precipitation the efficiency of which increases with the increase of particles size and filtration velocity up to a specific (critical) point (usually 1-2.5 m/sec) at which the secondary carryover of trapped liquid drops takes place.

Low-velocity mist eliminators are optimally equipped with a mix of glass fiber and a specific proportion of coarse and fine fibers. Coarse resistant fibers ensure uniform distribution of finer ones, increase the velocity of liquid discharge out of layer, giving the latter the mechanical strength and stability, and ensuring the operation of finer fibers throughout the layer. Usually the layers made of fibers 5-20 mcm in diameter and 88-92 % porosity are used . More often, the fibers 8 to 15 mcm in diameter with 50-60 mm layer thickness are used.
The basic material we use in filtering part is a special chemically-stable fiber glass FGM 145 in the form of multilayer needle-punched fabric resistant to concentrated and diluted acids. Besides, synthetic fibers of other types may be used depending on operating environment.
Hydraulic resistance: not more than 150 mm of water column.
Efficiency of mist eliminator of this type may be decreased in case the operating gas flow contains insoluble organic, metallic or mineral particles which may penetrate into the mist eliminator from the units installed before it. These may also be sulfate particles or chemically generated salts such as ammonium sulfate, ammonium nitrate, nitrosilic-sulfuric anhydride, nitrosilic pyrosulfite, etc.;
- in case the operating gas flow contains any amounts of HF or PH alkaline which cause the corrosion of fiber glass and may destroy the filtering part.
- in case the gas flow velocity is higher than 0.2 m/sec.
- in case the gas humidity is insignificant. The filtering part is efficient in humid state, and, in addition to the fiber thickness, the moisture creates “additional resistance” and Browning diffusion effect.
