Determination of  total acid or base number of oils and fats

The TAN/TBN Titrator is suitable for determination of Total Acid Number (TAN) or Total Base Number (TBN) of oils and fats. The acid number expresses the quantity of base required to neutralize all acidic constituents of the sample. It is a quality feature for freshness of oils and fats. The base number indicates the quantity of acid which can be neutralized by additives in mineral oils.

The device is conform to standards IEC 62021-1, ISO 3771, ASTM D 664, ASTM D 2896, ASTM D 4739. The measurement uses a potentiometric titration method in an anhydrous medium. The titration with titrant starts, once the oil sample is dosed into the reagent. The user has to enter the sample weight into the menu. The titration speed is precisely adjusted to the reaction rate by control algorithms.

The titration is performed automatically until the endpoint indication of measurement. At the end of the measurement, results are shown in mg KOH/g oil or several other units.

Highlights

TAN/TBN Titrator

The TAN/TBN Titrator consists of

  • an automatic volumetric titrator with potentiometric pH indication and integrated temperature sensor
  • a titration vessel with stirrer unit


The determination of TAN/TBN value is based on

  • an acid-base-titration in an anhydrous medium
  • a precise indication by an electrode filled with anhydrous ethanol/LiCl


Steps of the analysis are

  1. Calibration of the electrode
  2. Determination of the blank value
  3. Standardization of the titration solution
  4. Titration of oil samples

The TAN/TBN Titrator for determination of TAN or TBN is conform to standards:

IEC 62021-1
Insulating Liquids - Determination of Acidity - Part 1: Automatic Potentiometric Titration

ISO 3771
Petroleum Products - Determination of Base Number - Perchloric Acid Potentiometric Titration Method

ASTM D 664
Standard Test Method for Acid Number of Petroleum Products by Potentiometric Titration

ASTM D 2896
Standard Test Method for Base Number of Petroleum Products by Potentiometric Perchloric Acid Titration

ASTM D 4739
Standard Test Method for Base Number Determination by Potentiometric Titration
