<p>The invention relates to a method for distilling a multicompound liquid mixture, such as crude oil, including: (a) a step of preheating said mixture; (b) a step of evaporating said preheated mixture; and (c) a step of distilling said evaporated mixture, a method in which heat from step (c), the temperature of which is greater than 100°C, is used during the preheating step (a), and in which at least one step for separating said preheated mixture into a liquid portion and an evaporated portion is carried out, the latter portion corresponding to at least one component of the mixture and being directly treated during the distillation step (c), and the mixture treated during the evaporation step (b) being depleted of said evaporated portion, characterized in that it includes a complementary heating step, in which residual power having low heat level is used, the temperature of which is less than 100°C.</p> |
