One of the most common methods to separate organic slvents from their aqueous mixtures is thermal distillation. However, it is not suitable to separate azeotropes where the composition remains unchanged in the vapor and liquid phases along with having high energy requirements.The primary objective here is the application of carbon nanotube immobilized membrane (CNIM) for separation of organic solvents from their aqueous mixtures via sweep gas membrane distillation. The solvent flux, separation factor and mass transfer coefficient obtained with CNIM are significantly higher than the commercial membrane at different feed concentrations and temperatures.
