TNO (formerly ECN) presents the revolutionary HybSi® membrane that allows you to save up to 50% of energy and costs, increase product quality and reduce side products of separation processes significantly.

Dehydration of organic solvents and mixtures is an energy intensive process. Distillation and other thermal separation methods account for 80% of the energy consumed for industrial separations, which shows the need for more efficient separation. The HybSi® membrane can replace classical separation processes such as distillation. HybSi is stable in water at high temperatures, in (a)protic solvents, and in the presence of acids, which makes this membrane innovative in all ways compared to alternatives such as polymer and ceramic pervaporation or vapour permeation membranes. More details are provided in technology.

By using the hybrid silica membrane in dehydration or methanol removal from organic solvents and mixtures via pervaporation or vapor permeation important savings in both CAPEX and OPEX are possible, see the table below. Important fields of application are e.g. the dehydration of solvents like alcohols, ketones, aldehydes, aprotic solvents, organic acids, or to increase the productivity by water removal in reactive systems like esterification reactions. By combining the membranes with distillation in hybrid processes capacity increase or process debottlenecking is possible.
