Esterification in Reactive Distillation Column Using Software Packages: A Review
Abstract: Abstract: Reactive distillation is the combination of reaction and separation in a same column. This represents an exciting alternative to traditional liquid phase chemical reaction processing. In reactive distillation, separation of products from unconverted reactants allows for better conversion, because produce elimination put out of place equilibrium and forces the reaction towards completion. The energy requirement of the conventional column is very and requires large recycling costs. Reactive Distillation is …
