Advanced sulfur analysis with HDXRF

Petra is powered by High Definition X-Ray Fluorescence (HDXRF®) technology: an elemental analysis technique offering significantly enhanced detection performance over traditional XRF technology. This technique applies state-of-the-art monochromating and focusing optics, enabling dramatically ...


S, Ni, V, and Fe analysis of crude oil using HDXRF®

Test methods for measuring sulfur content, like ASTM D4294 and ISO 8754, have become critical for assessing the value of crude oil. The blending of crude oils from different sources has become more commonplace within the industry to meet specifications for the classification of sweet crude ...


Sulfur measurement advanced - a new 4294 analyzer

The Petra series delivers high-precision D4294 sulfur analysis across a broad measurement range. Petra MAX™ delivers D4294 sulfur analysis in addition to 12 elements from P to Zn, for rapid monitoring of critical elements like Ca, Fe, K, Ni, and V at sub-ppm levels.

Crude oil contaminants: chlorine and the desalting process

Crude oil contains many contaminants which present challenges to refiners. Some contaminants occur naturally in the crude oil and others are accumulated in the upstream process. The primary means to remove these contaminants is the desalting process.

In the desalting process, ...


Monitoring chlorine to prevent refinery corrosion

Chlorine in crude oil, if not removed, can hydrolyze during processing to form hydrochloric acid. The crude oil desalter is the first line of defense in the prevention of corrosion. However, in order to provide a proper defense, the correct chloride monitoring must be put in place.
