Reactive distillation is an important and challenging process. 9ne of the major deficiencies inthis technology is the lack of a quantitative, step-by-stepdesign pro­ cedure. A heuristic method to design reactive distillation columns is proposed in this thesis. It is a short-cut,method that couples heuristic methods with rigorous simulation.
