• ASTM D7041-04 • On-line Measurement of Total Sulfur • Simple Analysis Method • Minimal Hardware • Proven Gas Chromatograph Flame Photometric Detection • Low Range Sensitivity Application The demand for on-line measurement of fuel sulfurs in refi neries is growing as environmental regulators enact more stringent limits on sulfur levels in motor fuels. Availability of sweet crudes has decreased while legislation continues to lower the permissible levels of sulfur in motor fuels to decrease pollution. As these sulfur limits continue dropping, very few on-line process analyzers can measure the total sulfur levels accurately and reliably. But, the PGC2007 E2 Process Gas Chromatograph with a Flame Photometric Detector (FPD) by ABB Analytical provides a fi eld–proven on-line method, measuring trace levels of Total Sulfur in fuels. Method The Environmental Regulations, which continue to evolve, set the anticipated limit for total sulfur in gasoline and diesel fuel. In response, various technologies for gasoline and diesel fuel analysis have appeared on the market: x-ray dispersion, electrochemical methods, lead acetate paper tapes, UV fl uorescence and gas chromatography. Recent ASTM test results show most of these methods to provide inadequate repeatability and reproducibility for both gasoline and diesel samples, especially at the lower ranges soon to be required. The method employed in the PGC2007 E2 from ABB performs with excellent repeatability and reproducibility. Total Sulfur in Fuels PGC2007 E2 Series Process Gas Chromatographs
