| A laboratory study on liquid-liquid extraction (LLE) system was carried out in batch and dynamic modes to extract naphthalene from fuel-oil, using methanol as extractant. This study investigates the optimization of naphthalene extraction using methanol in both batch and dynamic LLE modes. In batch mode, a Central Composite Design (CCD) was applied to optimize extraction parameters: extraction ratio (R), contact time (t), temperature (T), and stirring speed (SS). In dynamic mode, a Box-Behnken Design (BBD) was used to evaluate the influence of feed input, extraction ratio, and successive extractions. Batch extraction yielded an optimum naphthalene removal of 80.62% at R = 1.5, t = 5 min, T = 5°C, and SS = 100 rpm. Successive extractions led to complete removal. Dynamic extraction achieved total elimination at 30 mL/h, R = 1.5, and three successive extractions. This study demonstrates the feasibility of using methanol for efficient naphthalene extraction. Future research should focus on solvent regeneration and industrial-scale applications. | ||
