The extractive distillation of a methanol and dimethyl carbonate (DMC) azeotrope system was taken as an example, the simulation optimization conventional process (CEP) dividing wall column (EDWC) were carried out by Aspen Plus software. In order to meet requirements separation, lower energy consumption investment cost obtained using univariate analysis optimal operating parameters EDWC. couplin...

The separation of mixtures with close boiling points is a critical task in the petrochemical industry, and one such mixture that requires o-xylene/styrene. STED process used to separate o-xylene/styrene, which contains certain amount organic sulfur product due limitations process. In this study, underwent enhancements attain effective styrene accomplish deep desulfurization. A sulfolane (SUL) N...

Feasibility of batch extractive distillation in rectifying column with a middle boiling entrainer is theoretically and experimentally studied. These processes are preferable when the entrainer is already present in the mixture to be separated. Separation of methyl acetate and cyclohexane (forming minimum boiling azeotrope) using carbon tetrachloride, and separation of chloroform and ethyl aceta...

Calcium sulfate exists in three forms, namely dihydrate or gypsum (CaSO4·2H2O), anhydrite (CaSO4), and hemihydrate bassanite (CaSO4·0.5H2O) depending on temperature, pressure, pH, formation conditions. The of calcium sulfates occurs widely nature many engineering settings. Herein, a dataset containing the experimental solubility data minerals, i.e., anhydrite, aqueous solutions is presented. co...
