Determination of the Acid Number in Crude Oil and Gas Oil as per ASTM D8045

Monitoring the acid number in raw oil and raw oil products is the prerequisite for a well-functioning corrosion monitoring system that avoids unnecessary costs and downtimes. This Application Note describes the protocol for the determination of the acid number of raw and gas oil through catalytic thermometric titration using the 859 Titrotherm in accordance with ASTM (American Society for Testing and Materials) D8045. The Thermoprobe temperature sensor makes the 859 Titrotherm the ideal sensor for thermometric titration, as it can follow any change in temperature quickly and accurately.
