EXTRACTION OF NAPHTHALENE IN DYNAMIC MODE, APPLICATION OF BOX-BEHNKEN DESIGNF. BENDEBANE, F. HALAIMIA, L. BAHLOUL, L. BOUZIANE AND F. ISMAILAbstract This study was conducted to regenerate contaminated fuel oil which was used to extract naphthalene from the coke gas in an industrial steel plant and was rejected at the end of the process illustrating really serious problems in environmental pollution. The main objective of this work was to study naphthalene extraction from fuel in a continuous reactor stirred perfectly. Using an optimized DMSO-Methanol-phenol mixture as extractant, a Box Benhken Design was chosen to enhance the performance of the naphthalene extraction. From ANOVA analysis, effects of operating parameters (feed Input, stirring speed and volume ratio of the fuel oil on the extractant mixture) were studied and regression models linking the response to the various factors were developed. Using the response surface methodology (RSM), the optimized extraction yield of naphthalene in dynamic mode given by the theoretical model reached 79 %. In optimized conditions, the experimental validation which yielded 76.90%, was in a good agreement with the theoretical model.
