Eliminate Blue Smoke Emissions at Your Asphalt Plant
For instance, New York State’s Department of Environmental Conservation recently proposed new air regulations on blue smoke control at asphalt plants. The new regulations will affect liquid asphalt storage tanks, hot-mix asphalt storage silos, pugmills, truck loadout, and drag conveyors. Similarly, The Utah Division of Air Quality soon will require regulation of blue smoke and volatile organic compound (VOC) emissions from HMA plants. Its new Rule 313 requires HMA plant operators to control both VOCs and blue smoke emissions in the production and loading of HMA and at asphalt storage tanks. Owners and operators must comply by May 1, 2025. Blue Smoke Control, a division of Butler-Justice Inc., based in Anaheim, California, offers a patented, proven system that can eliminate emissions challenges and help producers meet new regulations. In addition, the Blue Smoke Control system can also keep producers on course to meet climate goals as part of NAPA’s “The Road Forward” initiative. The Road Forward challenges asphalt producers and pavers to develop technologies and processes that can help the industry achieve net-zero carbon emissions by 2050. Because blue smoke is essentially vaporized oil at high temperatures, Blue Smoke Control’s ducting system bleeds ambient (outside) air at key points and captures blue smoke from emission points in the asphalt production process. The system captures blue smoke from numerous points – including transfer points, silo filling, and truck loading. Seven stages of filters help to coalesce the tiny oil vapor droplets and aerosols into larger droplets that can be filtered out by the blue smoke collector. The oil droplets drain from the filters via gravity to a collecting sump. In some cases, the system can pull as much as 20 l/d of oil from conveyor transfer points, silo-filling spots, and truck load-out areas. Not only is the final high-efficiency filter 95% efficient at capturing particles as small as 0.3 μ (creating a filter that is equivalent to HEPA quality), the complete system is 99.9% efficient overall. With the Blue Smoke Control system, emissions from hot-mix plants can be reduced to nearly zero, providing owners with the means to achieve the highest level of environmental stewardship. Implementation of this technology has been proven to virtually end calls from nearby neighbors regarding visual emissions. Blue Smoke Control can be incorporated into new plant designs, and it is also easily retrofitted into existing plant operations, with minimal modifications to the plant. It is easy to use and to maintain. “The addition of RAP, rubberized asphalt, and polymer blends into asphalt mix designs has led to higher emissions due to higher mix temperatures. We provide the only environmental control devices that can easily be installed into any asphalt plant to remove up to 99.9% of blue smoke associated with asphalt production. Our Blue Smoke Control will eliminate the nuisance calls from neighboring residents and businesses,” according to Mike Butler, president of Butler-Justice. Blue Smoke Control division of Butler-Justice Inc. is a leading supplier of complete blue smoke control and odor control systems that eliminate both the blue haze typically found during the production of hot mix asphalt, as well as odor-causing VOCs. With hundreds of successful installations in the continental U.S., as well as Canada, Mexico, Australia, and Europe, Blue Smoke Control achieves the highest standards of emissions control, with reasonable initial investment costs and economical ongoing expenses.
