Patent
·
OSTI ID:6482977
A method is disclosed for cleaning a fluorine-containing waste gas evolved from a furnace, by contacting said gas with a fluorine-reactive powder and filtering the fluorine-reactive powder by a filter, an improvement comprising cooling the waste gas to 150 to 400/sup 0/C; feeding a fluorine-reactive powder into the cooled waste gas; passing the cooled waste gas through a filter on which the fluorine-reactive powder is deposited so as to react with the fluorine component of the waste gas; and removing the deposited powder layer from the filter.
