Save as much as 36% in maintenance preventing chlorine corrosion using ASTM D4929

Purchasing cheaper opportunity crude oils can increase your refining margin significantly. However, most opportunity crudes contain higher levels of compounds that are detrimental to the refining installation. Refineries who can best manage the balance between the lower feed costs and the higher maintenance costs will therefore be the most profitable. As much as 36% of maintenance costs of refineries can be linked to corrosion. Organic chlorines, and many sulfur compounds can cause severe corrosion. Therefore control of chlorine and sulfur levels is essential for keeping maintenance costs low.

In this webinar, ASTM International’s Executive Director, Taco van der Maten presents on the ASTM D4929 testing method of low level chlorine in crude. Primarily on how you can increase your margins while reducing your maintenance costs. He will share about the updates to this testing method which looks towards the energy dispersive X-ray fluorescence (EDXRF) technique as an alternative to titration analysis. Titration as you might know, requires skilled operators, is time and chemicals-consuming and yields less repeatable results. As a bonus, Taco will also update on how it is possible to conduct simultaneous analysis of chlorine sulfur and other elements of interest like vananium and nickel in crude oils and distillates.
