A methodology for process intensification that reduces the number of pieces of equipment as part of the design of a chemical process is presented. The method is based on three stages, the first one to detect feasible process alternatives, the second one to identify intensification opportunities, and in the third one phenomena building blocks are used to develop the best intensified process. The methodology is applied for the intensification of an aldolization process for the synthesis of dioxolane products, based on reacting ethylene glycol and 1,2-butanediol with acetaldehyde to produce 2-methyl,1,3-dioxolane (2MD) and 4-ethyl,2-methyl,1,3-dioxolane (4EMD). It is shown how a base flowsheet is effectively converted into an intensified reactive distillation process with the application of the intensification methodology.
