Crude Oil Removal

The present paper describes the process optimization study for crude oil degradation which is a continuation of our earlier work on hydrocarbon degradation study of the isolate Stenotrophomonas rhizophila (PM-1) with GenBank accession number KX082814. Response Surface Methodology with Box-Behnken Design was used to optimize the process wherein temperature, pH, salinity, and inoculum size (at three levels) were used as independent variables and Total Petroleum Hydrocarbon, Biological Oxygen Demand, and Chemical Oxygen Demand of crude oil and PAHs as dependent variables (response). The statistical analysis, via ANOVA, showed coefficient of determination R2 as 0.7678 with statistically significant P value 0.0163 fitting in second-order quadratic regression model for crude oil removal. The predicted optimum parameters, namely, temperature, pH, salinity, and inoculum size, were found to be 32.5°C, 9, 12.5, and 12.5 mL, respectively. At this optimum condition, the observed and predicted PAHs and crude oil removal were found to be 71.82% and 79.53% in validation experiments, respectively. The % TPH results correlate with GC/MS studies, BOD, COD, and TPC. The validation of numerical optimization was done through GC/MS studies and   % removal of crude oil.

Oily wastewater is one of the environmental concerns nowadays. The seriousness of oil pollution problem comes in sync with the expansion of oil exploration and production activities, as well as industrial growth around the world. In this study, the ability of sugarcane bagasse in removing oil in synthetic oil wastewater was investigated. Parameters affecting oil removal such as concentrations of synthetic oil wastewater, biosorbent dosage and contact time were optimized using Response Surface Methodology (RSM) via Box Behnken Design. Sugarcane bagasse showed excellent efficiency in removing oil with percentage removal up to 98.73% at 1.3 h contact time with 3.06 g of biosorbent dosage and 16.9% of synthetic oil wastewater concentration. The use of sugarcane bagasse in removing oil in water was successfully prove in this study.

Breakfast cereal plays an important role in a balanced diet. In Malaysia, tons of highly nutritious banana peels, overripe, oversupplied and rejected bananas end up in food waste, as a result of high production and consumption of banana. Thus, this study aimed to produce flaked breakfast cereal with banana pulp, banana peel and cornmeal through oven -baking. Baking temperature, baking time and volume of banana pulp and peel mixture were optimized by using response surface methodology (RSM) to achieve desired fracturability and yellowness. Through this study, fracturability (R2 = 0.98, P≤0.05) and yellowness (R2 = 0.99, P≤0.05) were found to be significantly related to the processing parameters and formulation of the flakes. The optimum processing parameters and formula obtained from this study were the baking temperature of 129.5°C, baking time of 15 mins and volume of banana pulp and peel mixture of 140 g. Besides, a sensory evaluation was conducted and compared among the optimized flakes and commercial corn flakes. Based on the results, there was a significant difference (P≤0.05) in aroma, appearance and taste but no significant difference (P>0.05) in mouthfeel and overall acceptability between both types of flakes. It was recommended that the shelf-life study of the optimized flakes could be done for future study.

The abandoned oil-based drilling fluid is a kind of water-in-oil system with high oil content, which has a significant recovery value. The effects of demulsifier dosage, heating temperature, ultrasonic time and centrifuge speed on the oil recycle were investigated in the chemical demulsification-ultrasonic treatment of oil-based drilling fluid. From the results of the experiment, BSF-L62 was a suitable reagent with the highest oil removal rate among the selected demulsifiers. The main influencing factors were optimized using the Response Surface Methodology based on Box-Behnken design. The oil removal rate was up to 76.9% under the optimal conditions of demulsifier dosage of 250 mg/L, heating temperature of 70 °C, ultrasonic time of 12.5 min and centrifuge speed of 7000 r/min.
