  • Opacity filtering system
    Patent number: 8286673
    Abstract: This system provides for odor control by using a rack opacity filtering system (ROFS). This is a system that collects opacity at the point of origin and transfers it to the filter unit. The filter unit then removes the opacity from the air and the clean air is then vented to the atmosphere. The opacity is a result of loading additized asphalt product at elevated temperatures and controlling how much opacity is allowed to be released. ROFS provides a means to virtually eliminate opacity.
