| titleOfInvention | Method for revamping a conventional mineral oils refinery to a biorefinery |
| abstract | The invention relates to a method for revamping a conventional refinery of mineral oils into a biorefinery, characterized by a production scheme which allows the treatment of raw materials of a biological origin (vegetable oils, animal fats, exhausted cooking oils) for the production of biofuels, prevalently high-quality biodiesel. This method allows the re-use of existing plants, allowing, in particular, the revamping of a refinery containing a system comprising two hydrodesulfurization units, U 1 and U 2 , into a biorefinery containing a production unit of hydrocarbon fractions from mixtures of a biological origin containing fatty acid esters by means of their hydrodeoxygenation and isomerization, wherein each of the hydrodesulfurization units U 1 and U 2 comprises: a hydrodesulfurization reactor, (A 1 ) for the unit U 1 and (A 2 ) for the unit U 2 , wherein said reactor contains a hydrodesulfurization catalyst; one or more heat exchangers between the feedstock and effluent of the reactor; a heating system of the feedstock upstream of the reactor; an acid gas treatment unit downstream of the reactor, containing an absorbent (B) for H2S, said unit being called T 1 in the unit U 1 and T 2 in the unit U 2 , and wherein said method comprises: installing a line L between the units U 1 and U 2 which connects them in series; installing a recycling line of the product for the unit U 1 and possibly for the unit U 2 , substituting the hydrodesulfurization catalyst in the reactor A 1 with a hydrodeoxygenation catalyst; substituting the hydrodesulfurization catalyst in the reactor A 2 with an isomerization catalyst; installing a y-pass line X of the acid gas treatment unit T 2 of the unit U 2 ; substituting the absorbent (B) in the acid gas treatment unit T 1 with a specific absorbent for C02 and H2S. The operative configuration obtained with the method, object of the present invention, also leads to a substantial reduction in emissions of pollutants into the atmosphere, with respect to the original operative mode. The invention also relates to the transformation unit of mixtures of a biological origin obtained with said conversion method and particularly hydrodeoxygenation and isomerization processes. |
