Abstract
The present invention discloses a method and apparatus for continuous analysis of a gas and particulate stream. More particularly, the present invention provides a method and apparatus for continuously analyzing a gas and particulate exhaust stream comprising metal fluorides to determine the fluoride concentration of such stream. A sampling nozzle communicating with a sampling line is placed in a gas and particulate stream. A gas-dissolving solvent is injected into a portion of the stream in the inlet portion of the sampling nozzle forming an aerosol. This portion of the stream and aerosol form a mixture comprising aerosol, gas and particulate which flows through the outlet portion of the sampling nozzle and through the sampling line. The aerosol in the mixture impinges against the inner surface of the sampling line wetting such inner surface with solvent; such mixture is scrubbed in the sampling line to enhance dissolution of gas in the solvent. The solvent and particulate in such mixture are separated from undissolved waste gases in the mixture, and such separated solvent and particulate are transported to a continuous analysis means to determine the concentration of dissolved ga…
