ABSTRACT:
The present invention provides method of contemporaneously forming a particulate glass batch composition and reducing volatile components in an exhaust stream, comprising the steps of: (a) introducing an exhaust stream comprising one or more volatile components into a mixing chamber; (b) adding a particulate glass batch precursor composition comprising at least one reagent material that is reactive with at least one of the one or more volatile components of the exhaust stream into the mixing chamber; (c) reacting at least a portion of the particulate glass batch precursor composition with at least a portion of the one or more volatile components of the exhaust stream in the mixing chamber to form a particulate glass batch composition and reduce the amount of the one or more volatile components in the exhaust stream; (d) separating the particulate glass batch composition from the exhaust stream; and (e) venting the exhaust stream having a reduced amount of volatile components to the atmosphere. In one particular embodiment of the invention, the at least one reagent material is selected from the group consisting of alkali earth compounds, alkali metal compounds, aluminum compounds, silicon compounds and mixtures thereof, and the reagent material is added in an amount that is at least five times a stoichiometric molar amount necessary to completely react with the at least one of the one or more volatile components in the mixing chamber.
