Abstract[English]
A method of removing paraffinic wax from pyrolysis oil that includes flowing pyrolysis oil into a tank and reducing the temperature of the pyrolysis oil to a temperature that causes the paraffinic wax that is in solution in the pyrolysis oil to precipitate and form (1) paraffinic wax in solid form and (2) remaining pyrolysis oil in liquid form. The method further includes pumping the remaining pyrolysis oil from the tank to a first location. The method then involves heating the paraffinic wax in solid form to form paraffinic wax in liquid form and pumping the paraffinic wax in liquid form to a second location. In this way, the paraffinic wax and the remaining pyrolysis oil can be processed separately according to their respective properties.[French]
La présente invention concerne un procédé de retrait de cire paraffinique à partir d'huile de pyrolyse, qui comprend l'écoulement d'huile de pyrolyse dans un réservoir et la réduction de la température de l'huile de pyrolyse à une température qui amène la cire paraffinique qui est en solution dans l'huile de pyrolyse à précipiter et à former (1) de la cire paraffinique sous forme solide et (2) l'huile de pyrolyse restante sous forme liquide. Le procédé comprend en outre le pompage de l'huile de pyrolyse restante du réservoir à un premier emplacement. Le procédé met ensuite en jeu le chauffage de la cire paraffinique sous forme solide pour former de la cire paraffinique sous forme liquide et le pompage de la cire paraffinique sous forme liquide à un second emplacement. De cette manière, la cire paraffinique et l'huile de pyrolyse restante peuvent être traitées séparément en fonction de leurs propriétés respectives.
