TOTAL MERCURY DETERMINATION IN NAPHTHAS BY EITHER ATOMIC FLUORESCENCE OR ABSORPTION SPECTROSCOPY

Open publisher page 7 citations

Abstract

Mercury determination in light hydrocarbon fractions and natural gas condensates, has long been an important issue in the oil industry. Mercury has to be monitored, because of the many problems encountered with this metal in reforming and processing. The main objective of this study was to develop a fast reliable methodology to quantify total mercury in naphtha fractions. Since there is no certified standard analysis procedure for Hg in naphtha, two methodologies with different operating principles were implemented, namely: atomic fluorescence spectroscopy with thermal desorption (AFS-TD) and atomic absorption spectroscopy with electrothermal atomization (AAS-ETA). The statistical treatment applied was paired t-test (95% confidence level), which showed that both techniques are statistically equivalent.
