Abstract The conventional process for methanol-water separation like distillation consumes about 60 %
of total energy. As an alternative, researchers have developed a membrane-based separation
process for alcohol-water mixtures separation. However, there is a big challenge for researches
to separate alcohol-water aqueous mixtures using a polymeric membrane because of swelling.
In the present work, the aim is to separate methanol from water by pervaporation using polymeric
membranes made up of polyvinylidenefluroide (PVDF) and polyethylene glycol (PEG200) modified
PVDF membranes. The membranes were characterized by thermogravimetry analysis (TGA),
field emission scanning electron microscopy (FE-SEM), and Fourier-transform infrared… More >
