With the support of EFRO and: PERVATECH Process Intensification by Pervaporation Martin Wolf, Rob de Lange, Frans Velterop Pervatech BV, Rijssen, The Netherlands [email protected] In-situ removal of water or methanol in condensation reactions is a most suited method to intensify production of e.g. esters and ethers. By removing the by-product Conventional esterification processing formed during the condensation reaction a higher yield of product is achieved and Reactor Downstream, post-treatment operations possibly less intense catalytic measures are necessary. Azeotropic distillation Vacuum distillation for Salting process Water washing removal of entrainer Clean product Polishing filtration By applying hydrophilic Modern chemical reaction with in-situ water removal and polishing filtration. silica membranes in inOnly possible with the aid of hybrid silica membranes. situ dehydration mode All downstream units converted into reactors. the efficiency of e.g. Hence 5 reactors with 100% filling. esterification processes can be significantly improved.
