Determination of Total Chlorine in Oil Samples as Per ASTM D4929

Oil refinery and clouds in sky.

The presence of chlorine in crude oil can hydrolyze during the refinery process to form hydrochloric acid which causes corrosion. Corrosion at petroleum refineries is a critical problem which exists at many places around the globe and has a huge cost impact in terms of maintenance.
Therefore, an effective chloride monitoring solution should be implemented and many refineries have a periodic testing of inorganic chlorides in place. A well-known, reliable and sensitive test method for the chlorine analysis in crude and fuel oil products is oxidative micro coulometric technique which has been applicable at the EST Total Chlorine analyzer, model
