The Fiber Bed Mist Eliminator has proven to be ideal for sulfuric, nitric, and thermal phosphoric acid plants; chlorine and other chemical plants; pulp and paper plants; textile plants; asphalt saturation towers; food processing; forming. Applications containing fluoride, high pH or steam can use special carbon fibers.
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).
- 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.

Fiber bed mist eliminators can be used in a variety of applications including cold heading machines, EDM machines, hot forging, and parts washers. The unit exceeds OSHA standards and is able to comply even as OSHA updates standards.
Particles of 3 microns or larger are collected when their moment (kinetic energy) prevents them from following the gas streamlines around a fiber. The moment the particle causes it to remain on its path reaching the fiber where it is captured.
Since momentum is a function of the particle's mass and velocity, it follows that large drops will be collected more efficiently than small drops traveling at the same speed. This type of mechanism is extremely dependent on the particle inertia and the viscosity of the gas.
Some particles follow the path
of the gas, but due to their diameter, they end up“touching" the fibers of the bed, where they are collected.
Mechanisms are little dependent on inertia, particle, and gas viscosity.
Sub-chromic particles are collected when their moment (kinetic energy) prevents them from following the gas streamlines around a fiber.
The moment of the particle causes it to remain on its path reaching the fiber where it is captured.
Since momentum is a function of the particle's mass and velocity, it follows that large drops will be collected more efficiently than small
