Abstract:
The measurement of sulfur in petroleum products has been practiced for many years. Recently, additional elements have become a source of concern in crude oil samples. One approach to this challenge has been to develop a new X-ray instrument for each required element. This has proven to be an expensive solution, which takes up a lot of laboratory bench space. Another approach has been to design the analysis of all elements into one instrument.
This newer approach, however, does have challenges, which need to be overcome. With all analyses in one instrument, inter-element effects must be addressed. This challenge becomes even more daunting when neighboring elements are being measured with one at very high percentages and the other at PPM levels. This challenge has been overcome with monochromatic EDXRF technology. This technology has already been approved as D7220 and is being used to measure a wide variety of samples from sulfur in automotive fuel and jet fuel to chloride in crude oil at low levels.
This presentation will discuss the technology itself and the many benefits including east of use. The data from several different studies will be shown and the data quality discussed. Newer applications with different elements will be reviewed.
