• Abstract:

  The intense search for renewable energy sources and sustainable processes aimed at reducing environmental pollution and global warming has stimulated the global market for biofuels. Biodiesel has great prominence in the national energy matrix, however, its large-scale production generates large amounts of glycerin. Glycerin has many industrial applications when it is purified. Purification through membranes has many advantages, especially in terms of the environment. With the use of mixtures containing glycerin, it is possible to study the behavior of filtration, since the consequences in the use of ethanol and biodiesel, for example, are different. Analyzing mixtures with similar compositions, varying the composition of biodiesel and ethanol only, the filtration flow is greater with greater presence of biodiesel, but the membrane clogging is greater, and therefore the filtration time is also smaller.
