Microporous methylated silica membranes have been made and tested up to a size of 1 m2 of membrane area and they can be used for the separation of methanol from organics. Measurements have shown that fluxes are much higher than for polymeric membranes with good selectivities and that the membranes can be used up to at least 125oC. Economic calculations have shown that these inorganic pervaporation membranes can very well replace existing - distillation based - processes.
