Membrane ultrafiltration of crude soybean oil Original Research Article

In the present work, it is evaluated the influence of temperature and transmembrane pressure on the crude soybean oil permeate flux through a ceramic tubular membrane (pore size 0.01 μm) and a polysulphone hollow fiber membrane (pore size 100 KDa). Temperatures and pressures values are 50, 60 and 70°C, 3.0, 4.5 and 6.0 bar, for the ceramic membrane; 50, 60 and 70°C, 0.7 and 1.4 bar, for the polysulphone one. Furthermore, it is also verified some physical properties of the permeate.
