  • Patent number: 6923851
    Abstract: The blue smoke control collector system is used for the collection of the blue haze which is actually comprised of tiny oil droplets that hover over hot asphaltic concrete mix. The system is designed to collect and filter the air generated at hot mix asphalt transfer points, asphaltic concrete silo loading areas and truck loading areas and to remove the oil therefrom. Oil captured in the system settles into a plenum and is then drained therefrom for suitable disposal. The filtered air can be released in to the atmosphere. An optional activated charcoal filter stage can be included to reduce odor in the released air.
