PGC2007 E2 Series (Process Gas Chromatograph) - Total Sulfur in Fuels0 pages

• 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.
