| Abstract Scope |
Since its inception it has been recognized that fluoride emissions from aluminium smelters have posed risks to sensitive species of flora and various types of fauna that graze on vegetation near such locations. After WWII the mass emission rates from smelters drove the development of pot hooding and fume capture directed to wet scrubbers. Continued growth in production and the associated mass emission rates then drove the industry to implement dry scrubbing technologies. Today, with smelter projects of 400,000 tonnes/year or more, simple rate based (kg total fluoride/tonne and kg SO2/tonne) limits can pose similar threats to flora and fauna. These are the direct result of the fugitive mass emissions from potroom roof vents or other areas with fugitive losses. This paper examines whether additional control technologies and other strategies are required for mitigation of these emission impacts. |
