Milán-Cárdenas AbstractThe presence of water in water-in-oil emulsions is a significant operational problem in the oil industry due to its impact on corrosion, scale formation, and increased costs during crude oil transportation and processing. This study evaluates the efficiency of a semi-organic demulsifier obtained from Mangifera indica L. leaf extract for the dehydration of light crude oil as a sustainable alternative to conventional synthetic agents. The aqueous extract was obtained using maceration and Soxhlet methods and evaluated in synthetic W/O emulsions (80:20 v/v) prepared with a light crude oil of 32.87 °API from the Campeche Sound. Dehydration tests were performed in accordance with ASTM D-4007 at a temperature of 60 °C, using different concentrations of the demulsifier (500, 1000, and 2000 μL). Additionally, the crude oil was characterized before and after treatment by determining its density, API gravity, and SARA analysis. The experimental results showed that the semi-organic demulsifier was most efficient at a concentration of 1000 μL, achieving a higher water recovery than that obtained with a commercial demulsifier under the same operating conditions. At higher concentrations, a decrease in efficiency was observed, attributed to interfacial supersaturation phenomena that favor emulsion stabilization. The results indicate that Mangifera indica L. leaf extract does not significantly alter the physicochemical properties of crude oil and performs competitively, positioning itself as a viable alternative with low environmental impact and potential for industrial application in light crude oil dehydration processes.
