X-VOCS system eradicates odor-causing emissions produced as a byproduct during hot-mix asphalt production. Invisible emissions from plants—specifically, the odor-causing volatile organic compounds (VOCs) that reside in hot asphalt storage tanks—can create a number of challenges for producers, ranging from regulatory requirements to overt opposition from neighbors.


The X-VOCS System features proprietary carbon absorption technology designed to filter and remove up to 99%of odors and VOCs, such as Hydrogen Sulfide (H2S), from tanks. X-VOCS incorporates a five-stage filtration system. In the first three stages, a series of filters remove more than 95% of targeted particulates down to 0.3 microns. In the final two stages, carbon filtration beds remove the remaining odors and volatiles. The X-VOCS system is ideal for new plants, and also is easily retrofittable into existing operations, with minimal modifications to the plant.



Further, when the X-VOCS technology is coupled with the company’s 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 odor and visual emissions. Similar to X-VOCS, the Blue Smoke Control system is retrofittable with few plant modifications.
