Sulzer Chemtech has increased its activities in the field of thermal separation technology by the addition of membrane processes such as pervaporation / vapour permeation, membrane-based extraction / absorption and the pressure driven processes reverse osmosis, nano- and ultrafiltration.
Pervaporation / Vapour permeation
| • drying of solvents (ethanol, IPA, acetone, MEK, ethyl acetate etc.) to overcome azeotropes • recovery of complex solvent mixtures • energy-saving removal of solvents • organic and inorganic membranes • hydrophilic and hydrophobic membranes |
 |
Pressure driven membrane processes
| • Reverse osmosis, nanofiltration, ultrafiltration, microfiltration • Solvent, pH, temperature resistant membranes • Hydrophilic, hydrophobic, organophilic membranes • Polymeric and inorganic membranes • All kind of module configurations: Spiral, hollow fibre, tubular, cassette type • Dead end, cross flow and dynamic (high shear) filtration |
 |
Membrane-based extraction / absorption
Dispersion-free phase contact using membrane contactor technology
• solvent recovery from waste water streams • extraction of pharmaceutical and food components with low solvent requirement • bubble free aeration / degassing |
