PERVATECH Process Intensification by Pervaporation Martin Wolf, Rob de Lange, Frans Velterop Pervatech BV, Rijssen, The Netherlands [email protected] Conventional esterification processing Azeotropic distillation Vacuum distillation for removal of entrainer Salting process Water washing Clean product Reactor Downstream, post-treatment operations Polishing filtration Only possible with the aid of hybrid silica membranes. Modern chemical reaction with in-situ water removal and polishing filtration. Plant output: 667% Clean product Packed bed catalyst Pervaporation membrane package All downstream units converted into reactors. Hence 5 reactors with 100% filling. Polishing filtration 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 formed during the condensation reaction a higher yield of product is achieved and possibly less intense catalytic measures are necessary. By applying hydrophilic silica membranes in in- situ dehydration mode the efficiency of e.g. esterification processes can be significantly improved. With the support of EFRO and:
