FIBERWIND Candles

FIBERWIND™ type mist eliminators of AWS are specifically made to remove mainly submicron liquid or soluble solid particles from an air or gas stream. They are similar to mesh pad mist eliminators except that the filaments are extremely fine fibers, randomly but very closely spaced.

FIBERWIND™ mist eliminators of AWS are constructed in a cylindrical form (candle filters) between two concentric open mesh bed formers into which special fibers of various materials are either densely packed or wound or wrapped.

FIBERWIND™ mist eliminators are installed vertically on a tube sheet either in hanging or standing configuration. Because of the vertical disposition, liquid accumulating on the fibers is moved horizontally through the fiber bed by the drag of the gases and drains by gravity down the downstream side to the bottom of the fiber bed where it is collected and either returned to the process or removed as a waste.

Using extensive experience in industrial gas inlet conditions, fiber bed design, materials of construction and corrosion resistance, AWS can optimize the mist eliminator design for the highest efficiencies, lowest pressure drop and longest effective life while balancing cost and benefits in today’s cautious economic conditions. AWS engineers will work closely with the customer to determine the FIBERWIND product that best meets their needs.

FIBERWIND™ type BM (Brownian Movement)
This type of mist eliminator works at fiber bed velocities of about 0.10-0.15 m/sec depending on specific processes. The collection efficiency will be essentially 100% for all particles 3 micron and larger and 99.5% or more, for all particles smaller than 3 micron. FIBERWIND™ type BM have no turndown problems: thus the lower the fiberbed velocity, the higher thecollection efficiency, especially for submicron particles.

FIBERWIND™type IM (Impaction Movement)
This type of mist eliminator works at fiber bed velocities of about 1.0-1.5 m/sec depending on specific processes.The collection efficiency will be essentially 100% for all particles
3 micron and larger and 90-97% for all particles 1.0 micron and larger.
