For the ISPT Techno project: ”Recovery of aggressive solvents, which are difficult to separate”, Pervatech modified and tested ceramic membranes. These tests showed that it is possible to tailor a membrane towards an optimum for the separation of volatile aromatic organic components from an Ethanol/Water stream. The separation took place in a pervaporation process and resulted in an increase in the reusability of the ethanol from 3 times to approximately 50 times. The cost reduction in terms of less ethanol purchases and lower incineration volumes were calculated at 90%.
Tests performed at Pervatech on the industrial feed shows the potential of the pervaporation membrane technology for the cleaning of Ethanol streams and the possibilities for tailoring membranes towards a desired output.

Pervaporation using ceramic HybSi® membranes can deliver a 30 to 50 percent energy savings relative to conventional distillation. Particularly striking is that this ceramic membrane can be used up to a temperature of 150°C , while the maximum temperature for polymeric membranes is around 100°C. As a result, ceramic membranes enable a fourfold increase in throughput, thereby cutting the cost of materials up to 75 percent. That means the proper application and use of ceramic HybSi® membranes for pervaporation offers significant advantages, as demonstrated by a recently completed ISPT/NL GUTS techno project.
