Natural gas produced at high pressure (50-70 bar) is the only industrial source of helium (He). A membrane separation process may offer a more efficient production system with smaller footprint and lower operational cost than conventional cryogenic system. Inorganic membranes with high mechanical strength are known to exhibit good stability at high pressure. In this work, two inorganic membrane...

Nanofiltration is increasingly gaining attention in many separation and treatment processes such as water softening, color removal and separation of medicines. Nanofiltration membranes are often negatively charged, displaying separation characteristics in the intermediate range between reverse osmosis and ultrafiltration. In this research, a novel nanofiltration membrane prepared with poly(amid...

From water desalination and gas purification to metal recovery beyond, membrane separation has become integral numerous industrial applications [...]

beer is the most consumed beverage after tea, carbonates, milk and coffee in the world and it continues to be a popular drink. one of the important reason for its popularity is that beer is a drink with a pleasant flavor, an attractive color and also because of its clarity. so, membrane separation technology has become widely used in the food processing industryto attain these characteristics.a...
