XOS launches analyzer for testing critical elements in petroleum refineries
ALBANY, N.Y. — XOS has announced the worldwide release of Petra MAX, a new D4294 analyzer with combined analysis of 13 elements from P to Zn. Petra MAX delivers high-precision sulfur analysis in addition to rapid monitoring of critical elements like Ca, Fe, K, Ni, and V at sub-ppm levels.
Test methods for measuring sulfur content, like ASTM D4294 and ISO 8754, have become critical for assessing the value of crude oil, the company said in a press release. The blending of crude oils from different sources has become more commonplace within the industry to meet specifications for the classification of sweet crude oil. The introduction of new crudes brings new challenges, like higher concentrations of metals known to rapidly deactivate process catalysts in the catalytic cracker and hydrotreaters, and cause pump and exchanger fouling, and off-specification coke.
Petra MAX is powered by HDXRF, utilizing XOS patented doubly curved crystal optics coupled with a high-performance silicon drift detector and a monochromatic excitation beam. According to XOS, this technology reduces background noise and increases signal-to-noise output, enabling low detection limits and high precision without the need for consumable helium gas, a vacuum pump, or extensive sample preparation.
