Abstract

The article addresses the critical issue of crude oil quality control, specifically focusing on the determination of chloride salts (sodium, calcium, and magnesium), which exert a destructive impact on processing equipment. The paper provides a detailed analysis of the adverse effects of salts, which lead to severe equipment corrosion, scaling, and a reduced yield of valuable oil fractions. The chemical principles and specific applications of two standardized methods for analyzing aqueous extracts according to GOST 21534-2021 and ASTM D3230 are described: indicator (argentometric and mercurimetric) and potentiometric titration. The experimental section presents the results of a comparative analysis of crude oil samples before and after undergoing primary and deep dehydration and desalination processes. Based on the obtained data, a significant reduction in the mass concentration of salts is demonstrated, dropping from critical values (over 3,200 mg/dm³, corresponding to Quality Group 3) to the regulatory standards of commercial Group 1 crude oil (less than 40 mg/dm³). It is concluded that the preliminary treatment of the raw material is highly effective. Furthermore, the prospects for the digital transformation of oil quality control through the integration of sensor systems and artificial intelligence are outlined.
