In the present work, the optimization of different structural and process parameters of a divided wall column (DWC) for the energy efficiency has been presented. The optimal design and operation of divided wall distillation columns involve a number of variables and is a non-linear problem. Rigorous simulation of a DWC was carried out using Multifrac model of ASPEN Plus software. Box–Behnken des...

In the present study, simulation of a divided wall column (DWC) was carried out to study the product quality and energy efficiency as a function of reflux rate, liquid spilt and vapour split for the separation of C4-C6 normal paraffin ternary mixture. Rigorous simulation of the DWC was carried out using Multifrac model of Aspen Plus software. Box–Behnken design (BBD) was used for the optimizati...

This paper presents the micro-finishing of bevel gears by electrochemical-mechanical finishing (ECMF) process under different experimental conditions of current, rotating speed of workpiece and electrolyte concentration. These different experimental conditions are planned on the basis of box behnken design (BBD) design of experiments (DOE) technique of response surface methodology (RSM). An emp...

A novel method, BBD-SSPD is proposed by the combination of Box-Behnken Design (BBD) and Split-Split Plot Design (SSPD) which would ensure minimum number of experimental runs, leading to economical utilization in multi- factorial experiments. The brine shrimp Artemia was tested to study the combined effects of photoperiod, temperature and salinity, each with three levels, on the hatching percent...

In this study, a Box Behnken Design (BBD) and a Binary Logistic Regression (BLR) were applied to study the effects of demographic characteristics on the risk of HIV in South Africa. The demographic characteristics studied for each pregnant mother attending an antenatal clinic in South Africa, were mother’s age, partner’s age (father’s age), mother’s level of education and parity. Using the 2007...

Isoliquiritigenin (ILG) of licorice is a potential cancer chemopreventive agent. In this paper, response surface methodology (RSM) integrating with Box-Behnken design (BBD) was firstly employed to optimize the ILG extraction, which based on the single-factor experiments. According to analysis, the effect of extraction time and ethanol concentration on yields was significantly. The optimum value...

The walnut green hull is an agro-waste, a source of natural dye and volatile compounds with various biological activities, but the main challenge conventional extraction method quality quantity compound (dye) from waste. objective this research work to use microwave-assisted (MAE) as emerging technology. Further, MAE process was optimized using Box–Behnken Design (BBD) response surface methodol...
