Evaluación de la eficiencia operativa en unidades de diésel-II de la Refinería de Shushufindi

Abstract

Operational efficiency in Diesel-II production units is a key factor for the country's economic and energy sustainability. This project aims to evaluate such efficiency at the Shushufindi Refinery by analyzing yields, operational continuity, and fuel quality. The hypothesis states that operational deviations from design conditions negatively affect the profitability and competitiveness of the process. The study is justified by the need to reduce operational losses and dependence on imported petroleum derivatives. The project followed a quantitative and applied approach, using operational data provided by EP Petroecuador for the period August–October 2025. Statistical analysis tools, performance indicators, comparisons with design values and international references, as well as technical fuel quality standards, were applied. The results showed marked differences between the units: R1 achieved 88.4% utilization and a 40.4% yield, exceeding reference values; while R2 operated at 77.9% and 26.0%, respectively. Neither unit met the ULSD standard (15 ppm), with an average sulfur content of 163 ppm. These gaps generated an estimated opportunity cost of USD 417,764. It is concluded that the refinery has the technical potential to operate efficiently; however, operational and control improvements are needed to optimize Diesel-II production and competitiveness.
