20120612 DSM – Mr. Aris de Rijke: Development of a multiproduct reactive distillation column for unsaturated resins production

From considerations on the advantages (lower energy, reduced process time, more consistent product quality, lower capital) and the disadvantages (narrow operation window, reduced flexibility, product grade change challenges) DSM defined the potential of RD for their resins production. Combining the outcomes of their theoretical exercises and tests with the results of the TUe ISPT project, DSM developed their multiproduct RD column for their resins. DSM succeeded in designing the reaction and separation section of the RD column and developed almost zero loss operation strategies during product grade changes in this continuous process.

Production time reduced by 80%, energy consumption by >80% and capital by 20% www.dsm.nl
