Pervaporation membrane for solvent dehydration
Industries such as pharmaceuticals and biofuel production require effective dehydration of solvents. Traditional methods like distillation can be energy-intensive and often require additional chemicals or entrainers.
Efficiently dehydrate solvents using membrane technology
The pervaporation process by BORSIG is a membrane technology designed for efficient solvent dehydration. This technology relies on the high water affinity of the membrane material, allowing water or methanol to be preferentially adsorbed and permeated through the membrane. Depending on the feed flow and production needs, the process operates with either liquid or vapor feed and can be run in batch or continuous modes. Specifically, this technology is suited for applications involving azeotropes and high water-content solvents like ethanol, isopropanol, and trimethyl borate. By combining distillation with pervaporation, the system reduces water content down to 0.3 wt-% without additional chemicals, decreasing energy consumption and simplifying the separation process. BORSIG’s pervaporation is suitable for applications in pharmaceutical, nutraceutical, and fine chemical industries.
