the center of the design for analysis of variance was applied. Based on the statistical analysis, SRE was expressed by a model for the whole range of variables while WRE was expressed with two models, each is valid in a part of variable domains. The models were satisfactorilyevaluated with plant experimental data. The optimum values of demulsifying agent concentration, temperature, wash water dilution ratio, settling time and mixing time with wash water were fond to be 15 ppm, 77 oC, 10%, 3 min and 9 min respectively for SRE. For WRE based on two proposed models optimum values were found. 93.28% removal efficiency was found for salt removal. This value was 94.80% and 89.57% for water removal proposed models.
