In the present paper the experimental data of extractive desulfurization of liquid fuel using 1-butyl-3-methylimidazolium tetrafluoroborate [BMIM]BF4 have been presented. The data of FTIR, 1H NMR and 13C NMR have been discussed for the molecular confirmation of synthesized [BMIM]BF4. Further, the thermal properties, conductivity, solubility, and viscosity analysis of the [BMIM]BF4 were carried out. The effects of reaction time, reaction temperature, sulfur compounds, and recycling of ionic liqui
The possible application of imidazolium ionic liquids as energy‐efficient green material for extractive deep desulfurization of liquid fuel has been investigated. 1‐Butyl‐3‐methylimidazolium chloride [BMIM]Cl was synthesized by nucleophilic substitution reaction of n‐methylimidazolium and 1‐chlorobutane. Molecular structures of the ILs were confirmed by FTIR, 1 H‐NMR, and 13 C‐NMR. The thermal properties, conductivity, solubility, water content and viscosity analysis of [BMIM]Cl were carried out
This study proposes a systematic approach of analysis and optimization of the multi-effect distillation-thermal vapor compression (MED-TVC) desalination system. The effect of input variables, such as temperature difference, motive steam mass flow rate, and preheated feed water temperature was investigated using response surface methodology (RSM) and partial least squares (PLS) technique. Mathematical and economical models with exergy analysis were used for total annual cost (TAC), gain output ra
