Acid number in crude oil and mineral oil products

The acid number is an important parameter for the quality control and price determination of crude oils and mineral oil products. It permits important conclusions to be drawn about the quality of crude oil and refinement. Products with only slightly higher acid numbers have greater corrosion potential and lead to higher costs during later processing, which is why they are also traded at lower prices. This White Paper describes a rapid and reliable method for acid number determination according to ASTM D8045.
