Abstract

The EPA Remote Optical Sensing of Emissions (ROSE) System, which consists of a commercial FT-IR system and associated components installed in a van, has now been in use for over three years. The system is used in either the absorption mode with a remotely located light source (long paths through the atmosphere or short paths across industrial stacks) or in the single-ended emission mode to quantify the gaseous pollutants emitted from various types of sources. Spectra are usually obtained at a resolution of 0.125 cm-1 over the range 700 to 6000 cm-1. On two recent measurement programs the ROSE system was used to characterize the emissions from an aluminum refinery potroom and from a cement plant. The major potroom emission specie was HF; varying amounts of CF4, COS, CO, and SO2 were also observed. In addition to H2O and CO2, the cement plant emissions included NO, CO, HC1, NH3, SO2, and H2C0; a comparison was made between species concentrations deter-mined by cross-stack absorption and by single-ended emission.
