METHOD OF REDUCING FUMES FROM A VESSEL OF MOLTEN ASPHALT |
摘要 |
<p>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 upp er surface of the molten asphalt.</p> |
