Clora 2XP

Corrosion mitigation strategies are an important part of ensuring safe refinery operation and maximizing profitability Clora has become a critical part of identifying potential corrosion events and monitoring the effectiveness of these mitigation strategies. With over a decade of experience supporting refiner’s needs to monitor chlorine, XOS can provide many different solutions for monitoring organic, total, and inorganic chlorine in crude oil.

In this study, XOS test three real-world biofuel samples, showcase their concentrations, and then apply correction factors to mitigate biased results. The correction factors used were derived from the ASTM D7039 method, though these correction factors can still be applied for those in Europe adhering to the ISO 20884 method. As per Section 1 of ISO 20884, any sample with more than 3.7% oxygen content must be corrected for.

Russia’s Druzhba Pipeline contamination case is a globally relatable example of the ill effects of organic chlorides in crude oil. This application note shows that though other methods are available, ASTM D4929C, GOST 33342, and similar XRF methods allow refineries to obtain organic chloride concentrations in crude oil with increased precision and efficiency.

Monitoring chlorine for corrosion mitigation is critical during refining processes. In this application note, XOS demonstrates their range of benchtop and online chlorine analysis solutions, specifically the Clora®, Clora® 2XP, Sindie +Cl® and Clora® Online analyzer, designed to offer breakthrough analytical solutions for the determination of chlorine in liquid hydrocarbon samples such as aromatics, distillates and heavy fuels, and aqueous solutions.

Corrosion at petroleum refineries is a critical problem all over the world. In the United States alone, NACE International, a professional association dedicated to reducing the economic impact of corrosion, has shown that $3.7 billion in direct costs are realized annually from maintenance, vessel expenditures, and fouling as a result of corrosion. This huge figure does not take into account the estimated loss of as much as $12 billion in profit due to decreased capacity, unit outages, and premature turnarounds that result from corrosion.

On October 15, 2017, ASTM approved the addition of Procedure C to D4929 Standard Test Method for Determination of Organic Chloride Content in Crude Oil. Procedure C uses X-ray Fluorescence (XRF) to determine the chlorine content in the crude oil naphtha fraction. This is an important step forward, as users will be able to officially use XOS’ Clora, Clora 2XP, and Sindie +Cl analyzers for organic chloride analysis in crude oil without ASTM method modification.
