Licenses and patents

The HybSi® membrane and the necessary sealing and module technology are covered by a number of ECN patents. ECN is currently looking for interested parties (membrane manufacturers and system integrators) to take a license on its technology and broad patent portfolio. We can provide a detailed technology transfer and aim for a joined effort in the further scale-up and market development of HybSi® membranes. For more information please contact us.

Membranes and modules

ECN provides to selected end users two different single tube modules with HybSi® membrane. The first contains a membrane of ~40cm2 and the second ~400cm2. For more details and/or a price quotation please contact us. Download module information.

Process simulation and pervaporation calculation tool for flowsheeting and process evaluation

ECN has developed a calculation tool for pervaporation membranes that can be used for process evaluation and flowsheeting. The tool is an add-in to Aspen Plus and can be used for e.g. sensitivity and process optimization studies. >>

Laboratory measurements

ECN offers to perform pervaporation measurements for interested end users on their industrial mixtures. The emphasis is on water and methanol separation from organic solvents. To this end ECN has more than ten glass pervaporation set up available. For more demanding conditions a further 5 stainless steel autoclaves are available that can run up to 30 bars pressure and 200°C in a batch experiment set-up. These installations can run 24/7 including fresh feed addition. They are normally operated with one membrane of ~15 cm length and typically use 1-2 liter of feed liquid. For larger scale measurements with continuous flow feed conditions a set up with a feed capacity of ~35 liters is available. This set up can be run with six membranes in series with pressures up to 25 bars and temperature up to 150°C.

On site pilot testing

A further service that ECN offers is on site testing with a total membrane surface area of 1 m2. To this end a skid mounted test installation is available, that has passed a number of HAZOP analyses and is explosive proof. This unit can run batchwise as stand alone equipment using a 1000 liter feed vessel, or in line using a continuous feed.
