摘要

"The preparation process of absorber of oil and oil products.The product used as absorber of oil and oil products and the process of containment of oil spill and derivatives in the effluent lu00ecquido ".The present invention relates to a product obtained from EVA (ethylene copolymer of vinyl) and its compounds, intended for the absorption of oil and its derivatives.Independent of formula of the molecule, whether open or closed, such as oils, derived from coal tar, and pesticides, the invention also relates to a process for the preparation of such product.In order to improve the wing its absorption characteristics.The invention refers to a process of containment of spills of oil and its derivatives in liquid effluents, to prevent their spread.The preparation process of the absorbents petroleum and its derivatives includes the submission of the waste of Eve the following operations: the classification object density of waste EVA.In order to obtain a final product standardized; the grinding of the wastes classified by means of rotating knives mills, in order to obtain a proper range granolumu00e9trica.The operation of the classification by density selects the waste EVA between 0.12 to 0.32 g / cm ^ 3 ^.The grinding operation reaches a particle size range of waste EVA between 1.0 to 20 mm.The product used to absorb oil and its derivatives residues of EVA, which are classified by density and ground, resulting in a final product with homogeneous behavior.The residues of EVA includes a track density between 0.12 to 0.32 g / cm ^ 3 ^. The particle size range of the waste of EVA is between 1.0 to 20 mm.The process of containment of oil spill and its derivatives in liquid effluents used as absorption agent waste EVA classified as density and ground.Resulting in a final product as homogeneous behavior. The residues of EVA can be used in the form of grains released as barriers or bundles.
