Total Oil Count (TAN) Analysis in Mineral Oils

In mineral; One of the tests carried out to detect the deteriorations caused by additive depletion, acidic pollution and oxidation amount is Total Acid Number (TAN) Determination.

The acid number is defined as a measure of the acid concentration in a non-aqueous solution. It is determined by calculating the amount of KOH (potassium hydroxide) required to neutralize the acid in a gram of oil sample. The acid number determines weak organic acids and strong inorganic acids.

Changes in acid concentration in an oil; acidic contaminants, improper oil, alkaline reserve depletion, and oxidation by-products can be caused by acids. Additives in oils increase the Acid Number. As it is used, the decrease in additives in oils also reduces acidity. Likewise, being contaminated with acidic components increases the acidic content of oils.
