Petrochemical Compounds Characterization using Thermo Scientific FLASH 2000 OEA Analyzer
Aug 17 2011
Rapid and accurate percentage of CHNSO content in petrochemical compounds can be used with the relative heat value calculation to determine the sample quality for optimum engine performance. It also enables the identification of vehicle exhaust constituents that are harmful and hazardous to the environment.
New specifications and legislative limitations on hazardous and toxic pollutants from vehicle emissions were introduced due to the increasing atmospheric pollution. For example, the trend in developed countries is towards reducing the oxygen and sulfur contents in gasoline fuels because sulfur oxides formed during combustion may get converted into acids that promote corrosion of engine parts and exhaust systems, as well as being undesirable atmospheric pollutants. Sulfur also reduces the effectiveness of exhaust gas catalytic converters.
The Thermo Scientific FLASH 2000 CHNS/O Analyzer permits the fast quantitative determination of CHNS/O in petrochemical materials. To perform total sulfur determination at trace levels in many materials, such as gasoline, diesel, lubricants, graphite, etc. the FLASH 2000 Elemental Analyzer has been coupled with the flame photometric detector (FPD). This method combines the advantages of the elemental analyzer with the sensitivity, selectivity and robustness of the FPD.
