Precise determination of chlorine in petroleum is critical during refining processes. Chlorine may poison expensive catalysts and may lead to corrosion in overhead or reactor effluent systems. XOS Clora ¨ analyzers offer breakthrough analytical solutions for the determination of chlorine in liquid hydrocarbon samples such asÊaromatics, distillatesÊandÊheavy fuels, andÊaqueous solutions. Compliant with ASTM D 7536 Standard Test Method for chlorine in aromatics, the Clora ¨ analyzer uses the same Monochromatic WD XRF analytical technique as the widely accepted line of SINDIE analyzers. Clora ¨ provides a limit of detection of 0.15 ppm and a dynamic range up to 3000 ppm.
