Benchtop and On-line Chlorine Analysis
Breakthrough analysis of chlorine concentration at levels below 0.5 ppm without consumable gasses, without elevated temperature processes.
Precise determination of chlorine 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 as aromatics, distillates and heavy fuels, and aqueous 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. This direct measurement technique does not require gasses or involve high temperature processes which results in unprecedented ease-of-use and minimum maintenance requirements.
Chlorides are often present in crude oils and their concentration can vary greatly, depending on the origin of the crude. These chlorides, if not removed, can react to form highly corrosive hydrochloric acid in areas such as the crude tower overheads, leading to serious operational issues. Recently, there have been a few recent incidents where unexpected high levels of chlorine in a downstream process resulted in both significant economic loss and safety concerns. The need for a reliable online chlorine analyzer for refining process control is more important than ever for oil refining under the circumstances faced today.
The Clora On-line provides real-time chlorine concentration data with a dynamic range of 0.2 to 3,000 ppm wt%. Measurement time typically is 5 minutes; however, 15-second snapshot data is available to monitor process upsets. No titrations or extractions mean low maintenance.
