Dyes are widely used in various industries most of them are not readily biodegradable and are consisted of number of toxic, mutagenic, and carcinogenic compounds. Therefore, it is essential to remove them from effluent before their discharge to the environment. The objective of this investigation was to synthesize copper oxide (CuO) doped zinc oxide (ZnO) nanoparticles under mild hydrothermal c...

Abstract The epoxidation process of soybean oil (SBO) and peracid produced by 50 wt% hydrogen peroxide (H 2 O ) formic acid (FA) was studied with sulfuric SO 4 as a catalyst. Three reaction parameters, including temperature, FA-to-SBO ratio, H -to-SBO were investigated, along the combined effect on oxirane value (OV). Based response surface methodology (RSM), Box-Behnken design (BBD) used to op...

In this study, Box-Behnken”s Response Surface Methodology (RSM) was applied to study the esterification reaction effectiveness of acid activated Ngbo clay catalyst. The were monitored based on process conditions temperature, duration, amount reactant, catalyst weight and particle size. Box--Behnken’s indicates that clay-catalysed reactions proceed through dual mechanisms Acid-complex Alcohol-co...

Pre-hardened steel (P20) is a widely used material in the production of moulds/dies due to less wear resistance and used for large components. In this study, minimization of surface roughness has been investigated by integrating design of experiment method, Response surface methodology (RSM) and genetic algorithm. To achieve the minimum surface roughness optimal conditions are determined. The e...

Exergy analysis and response surface methodology (RSM) is applied to reduce the exergy loss and improve energy and exergy efficiency of acetic acid production plant. Exergy analysis is run as a thermodynamic tool to assess exergy loss in reactor and towers of acetic acid production process. The process is simulated in Aspen Plus(v.8.4) simulator and the necessary thermodynamics data for calcula...

Coagulation treatment of sago wastewater was studied and laboratory studies were carried out using alum as coagulant. Coagulation treatment conditions were optimised through response surface methodology (RSM). Operational parameters namely dosage of alum (Al [email protected]
