Determination of the total acid number of Brazilian crude oil samples: Theoretical and experimental evaluation of three standard methods
Fuel(2022)
摘要
•Three standard methods of total acid number (TAN) determination were compared.•Method scope, working range, precision, and effects of interferences were assessed.•The methods were used to determine the TANs of four Brazilian crude oil samples.•Sample solubility/size & hydrolyzable salt type/content affected method precision.
