Reactive Distillation Design: Analysis of the Process Statics

Techno-economic analysis of fuel ethanol production from cassava in Africa: The case of Tanzania

“…The rigorous calculation of the operating conditions in the distillation columns was performed using the module RadFrac based on the equilibrium method that employs the MESH equations (Mass balance equations, phase Equilibrium equations, Summation of the compositions, and Heat balance equations) using the inside-out algorithm. Residue curve maps were used for the conceptual design of the distillation schemes applying the principles of topological thermodynamics (analysis of the statics) (Pisarenko et al, 2001). Sensitivity analyses were performed in order to study the effect of the main operating variables (reflux ratio, temperature of the feed stream, ratio between the distillate and the feed, etc.)…”

Vapour reactive distillation process for hydrogen production by HI decomposition from HI–I2–H2O solutions

“…The method enables to determine the attainable extent of the reaction, the distillate and bottom products compositions and hints at the column configuration (approximate number of stages, localization and size of the reactive zone). The SA method assumptions [21] hold whatever the reactive phase, so that its extension to handle vapour phase reaction is straight forward, the mixture resulting from the reaction step and entering the separation device being then in vapour state.…”

Thermodynamic Characterization of <i>Saccharomyces cerevisiae</i> Catalyzed Fermentation of Cane Sugar

“…The value of P in Table 3 showed that the orientation of molecules affects the probability factor and that simple molecules indeed have more ways of proper orientation to form complex intermediates. Hence the probability factor is of the order for simple molecules [17,18]. For simple sugars like glucose, the orientation factor is expected to be large and hence the P value obtained in Table 3.…”
