MECS Brink® Fiber Bed Mist Eliminators:
HE (High Efficiency)
The original Brink design consists of fibers which are packed between two concentric cylindrical screens.
ES (Energy Saver)
This product consists of a special wound fiber bed, computer controlled quality, and a bicomponent drainage or reentrainment control layer of coarse fiber downstream of the finer collecting fiber.
Liquid that would reentrain from the fine fiber bed is drained in the reentrainment control layer. The ES element has become the product of preference in absorption tower service.
FP (Field Pack)
A special field replaceable non-woven sleeve design is available that allows the customer to replace the fiber packing on site. The FP offers comparable performance to the HE or ES style.
Mist Elimination Collection Efficiency vs. Particle Size
PARTICLES ARE COLLECTED IN THREE DIFFERENT WAYS:
Particles larger than three microns are collected when their momentum prevents them from following gas streamlines around fibers. They leave the streamline, strike a fiber and are collected by the fiber.
Between 1.0 and 3.0 micron size particles tend to follow the gas streamlines as they flow relatively close to fibers. A 1.0 micron particle, for example, passing within 0.5 micron of a fiber will be collected by the fiber.
Extremely fine particles have random side-to-side movement caused by collisions with gas molecules. A 0.1 micron particle will have about ten times the Brownian movement or random motion of a 1.0 micron particle, greatly increasing the probability of collision with a fiber.
