Abstract
The invention relates to a method and apparatus for a glass manufacturing facility. The apparatus includes a glass production system providing an exhaust stream entrained with particulate material including germanium—containing particulate. The apparatus further includes an exhaust filtration system including a PTFE fabric material. The exhaust filtration system is connected to the production system to receive the exhaust stream an capture the particulate material. A collection system is connected to the exhaust system to collect the captured particulate material from the exhaust system. The particulate material collected contains at least about 2% by weight germanium. The invention further includes incorporating the aforementioned apparatus into the operation of a glass manufacturing facility.
