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 mum) and a polysulphone hollow fiber membrane (pore size 100 KDa). Temperatures and pressures values are 50, 60 and 70degreesC, 3.0, 4.5 and 6.0 bar, for the ceramic membrane; 50, 60 and 70degreesC, 0.7 and 1.4 bar, for the polysulphone one. Furthermore, it is also verified some physical properties of the permeate.
