  • Method of reducing fumes from a vessel of molten asphalt
    Patent number: 6130276
    Abstract: In a method of melting asphalt in a vessel, the molten asphalt normally emitting fumes, 0.2 weight percent to 6 weight percent of a polymer is added to the asphalt to reduce the visual opacity of the fumes by at least 25% over the same asphalt without the polymer. In another embodiment, the total emissions of benzene soluble suspended particulates is reduced by at least 15% over the same asphalt without the polymer. Preferably, the added polymer has a melt flow index of from 15 grams/10 minutes to 95 grams/10 minutes, and the added polymer reduces the visual opacity of the fumes by forming a skim on the upper surface of the molten asphalt.
