A controlled blend

This article introduces an energy dispersive X-ray fluorescence (EDXRF) spectrometer for on-line elemental analysis in liquid process flows: Malvern Panalytical’s Epsilon Xflow. This technology enables the user to analyze, control and steer liquid-based production processes in real time, thereby optimizing production processes and blending operations. The analytical performance of the on-line spectrometer is demonstrated using two applications: on-line monitoring of the sulfur concentration in diesel to meet sulfur concentration levels prescribed by Euro VI, China VI, Bharat Stage VI, Tier 3 regulations, and the analysis of catalysts poisons in hydrotreating and fluid catalytic cracking (FCC) processes.
