As a novel study, esterification of acetic acid with methanol has been studied in simple batch reactive distillation apparatus to produce methyl acetate as main product and water byproduct. Novel solid catalyst named Indion 180 used this process. The can be distilled out two ways namely sequential simultaneous distillation. In the process, first reaction is carried till equilibrium total reflux...

E nergy costs are the largest percentage of a hydrocarbon plant’s operating expenditures. This is especially true of the distillation process, which requires substantial energy consumption. Concerns over recent high costs and economic pressures continually emphasise the need for efficient distillation design and operation without a loss of performance. This article illustrates how energy-effici...

Superior controllability of reactive distillation (RD) systems, designed at the maximum driving force (design-control solution) is demonstrated in this article. Binary or multielement single double feed RD systems are considered. Reactive phase equilibrium data, needed for analysis and design system, generated through an in-house property prediction tool. Rigorous steady-state simulation carrie...

Distillation has held a very strong position in the chemical process industries for well over century, and has, as separation method, been around millennia. The can be designed directly without need experimentation unlike other novel processes, distillation is standard part of any undergraduate curriculum. So why ongoing interest this dinosaur? Because distillation’s significant importance indu...

We experimentally demonstrate the two-step distillation of entanglement. The output of a first distillation stage underwent a second distillation step and was made available for subsequent steps. Our experiment displays the realization of the building blocks required for an entanglement distillation scheme that can fully overcome decoherence.
