Online Chlorine Analysis in Crude Oil and Petroleum Process Streams

Residue chlorine (Cl) content in desalted crude oil streams can be a serious issue due to its highly corrosive nature. Online monitoring of chlorine has an important economic aspect for the oil industry. An online total chlorine analyzer based on Monochromatic Wavelength Dispersive X-Ray Fluorescence (MWDXRF) has been developed for this purpose. This online chlorine analyzer is comprised of a low-power X-ray tube, an X-ray optical chamber, and a dynamic window module sample flow cell. An intense monochromatic beam coupled with a highly efficient doubly curved collection optic provides superior detection capability.
