Control Asphalt Emissions Efficiently and Economically

Control Asphalt Emissions
Efficiently and Economically

Air Clear Fiberbed Mist Collector
Systems Situation Analysis:

Asphalt Processing inherently creates visible fume emissions due to vaporization of light fractions from the hot asphalt. These light hydrocarbons condense, causing the smoke or blue haze emissions typical of these asphalt manufacturing processes. The condensed vapors typically form sub-micron particles which are very difficult to control using common filtration systems.

Traditional filters designed for dry particulate do not drain recovered mists well, creating the need for frequent filter replacement. Electrostatic devices foul quickly, again creating an expensive maintenance problem. Air Clear’s Fiberbed Filters have become the method of choice for many Asphalt Manufacturing and Production Plants due to their high efficiency, long filter life, and low maintenance.

With our Coalescing Fiberbed Filter Mist Collector Systems, Air Clear offers the most advanced technology available, all targeted towards the bottom line. Whether you have a single storage tank, a large coater, or an entire facility, Air Clear has the optimum solution for you!

Typical Asphalt Coater

2500 SCFM Regenerative Thermal Oxidizer (RTO) preceded by Fiberbed Filter Mist Collector System on Asphalt Roofing & Shingle Manufacturing Process in New Jersey.

Typical Asphalt Coater
System includes:

High efficiency cyclonic cooler, permanent pre-filter, high efficiency fiberbed diffusion filters, induced draft fan, and control package. Integral water/oil separators and other cooling and pre-filtration options available. Sizes to suit any capacity.

Air Clear also manufactures high efficiency replacement filters for many makes of mist eliminators. These filters often increase system performance without too much modifications. Simple installs and installation service also available.

Tank Vent

Tank Vent Systems often have no moving parts, relying on tank pressure to move the air through the system. Mounted at grade, radiant cooling condenses vapors before entering the filter. Standard sizes from 50 to 200 CFM, with and without fan. Air Clear is a full-service manufacturer of Industrial Air Pollution Control Systems.

In Addition to Mist Collector Systems, Air Clear designs and manufactures Recuperative and Regenerative Thermal and Catalytic Oxidizer Systems.
