Determination of Chlorine in Crude Oil

The fast and reliable determination of chlorine in crude oil and related matrices is important for refineries. The chlorine content in crude oil and its fractions is the main reason of corrosion, which causes considerable damage to pipelines and tanks and leads to catalyst poisoning. Monitoring methods based on combustion followed by coulometric titration have a great tendency to incomplete combustion (soot). They tend to errors caused by the matrix properties and increasing sample quantities. This can be prevented by the intelligent flame sensor technology of multi EA 5000 from Analytik Jena (Germany). It monitors and regulates the combustion, prevents soot and thus guarantees extremely accurate readings even for unknown samples.
