Abstract

Amine solutions are widely used to remove sour components (primarily H2S and CO2) from natural gas and light hydrocarbon gases. Removal of solids from amine solutions is essential for the efficient operation of gas purification plants. In this work, flat-surface composite membranes were synthesized using a phase inversion method based on polyvinylidene fluoride (PVDF) mixed with polyethylene glycol (PEG) and polyacrylonitrile (PAN). The use of polyvinylidene fluoride (PVDF), polyacrylonitrile (PAN), and polyethylene glycol (PEG) in a ratio of 15:5:5 in the preparation of the composite membrane allowed an amine solution flux increase of 18% during the filtration process and a ~97% removal of mechanical particles from the amine solution. These results were proven to be associated with an increase in the porosity and hydrophilicity of the surface of the PVDF composite membranes.
