METHOD FOR ANALYZING TOTAL REACTIVE SULFUR

摘要

The invention relates to a method for determining total reactive sulfur in a crude oil or fraction thereof using a mass spectrometer (Fig. 9) or gas chromatograph and mass spectrometer. Selecting fragment ions (1-4) characteristic of reactive sulfur species enables the quantitative determination of total reactive sulfur species (Fig. 5). Th e use of a low resolution mass spectrometer allows the rapid determination of total reactive sulfur in field or remote locations where mo re sophisticated instruments are not available.
