METHOD FOR ASSESSING THE ACIDITY OF PETROLEUM SAMPLES BY ISOTOPIC MARKING

摘要

evaluation method of low acidity of petroleum samplesthe quantities.applicable at any stage of the petroleum industry.it is marked by an isotope of a chemical elementin at least one acid function in petroleum samples. wethen determine the isotopic enrichment of samplesmsisotope ratio mass (irms). the acidity of the samples was inferred.thisas an alternative method for the measurement of total acid number(tan).in particular, it represents the only possibility of reliablethe acidity ofoil samples available in small quantities.- applications in the field of production, economic evaluationhydrocarbons.application to the determination of the range of carbon forthe acidity of a crude oil.application to the monitoring of the evolution of the distribution of the acid sitepolluted by oil.
