Using the new HybSi membrane technology from Pervatech can lead to savings up to 75% on equipment and 30 to 50% reduction on energy usage, by speeding up the process of condensation reaction mixtures by in-situ dehydration of the mixture, Pervatech says. Its most economical use is in breaking water/organic azeotropes, in the dehydration of condensation reaction mixtures and as an add on to distillation processes to expand capacity. It is also suitable for the separation of low-molecular-weight compounds such as NH3 and CH3OH from higher molecular weight solvents.
The membranes can withstand hydrothermal attacks, the presence of acids and aggressive organic solvents.
