Sulfur Review Preview

Every April, Hydrocarbon Engineering presents a selection of sulfur technologies and services currently available to plant and refinery operations. Here is a sneak preview of one of the entries from this year’s Review, courtesy of XOS:

XOS’ Sindie 2622 is easy to use, precise, and accurate. However, one drawback to the ASTM D2622 method is the requirement for duplicate determinations of samples ≤ 100 ppm. This equates to 20 minutes of measurement time on the traditional Sindie 2622 Gen 2.

Sindie 2622 Gen 3 now offers a time-saving solution to this problem, with the option to reduce the background measurement time to 20% of the total measurement time. It is now possible to get duplicate low-concentration sulfur measurements on Sindie 2622 in 12.5 minutes while still complying with D2622.

ASTM Proficiency Testing Programs (PTP) are statistical quality assurance programs that enable laboratories to evaluate and improve performance. XOS compiled sulfur data from the ASTM monthly reformulated gasoline (RFG) and ultra-low sulfur diesel (ULSD) PTP programs between 2015 – 2017 to compare the precision of the most commonly used sulfur test methods: D2622, D7039, and D5453. Whether monitoring ULSD or considering the refinery process strategy, refiners should take care when selecting the methodology for elemental analysis. With better precision as identified in the ASTM PTP data, MWDXRF analysers utilising ASTM D7039 methodology offer users reliability when evaluating sulfur in automotive fuel.

Sindie® Online is an industrial grade process sulfur analyser with detection capability to monitor ultra-low sulfur in petroleum or aqueous process streams. This process analyser presents an excellent solution for refineries and pipeline terminals where measurement speed and reliability are essential. Powered by MWDXRF, Sindie Online uses ASTM D7039 technology and delivers real-time, continuous analysis of total sulfur from 0.5 ppmw up to 3000 ppmw. This process analyser is ATEX and NEC certified for hazardous area locations.
