Abstract (en)
[origin: EP0621334A1] Process for obtaining an internal combustion engine fuel from a hydrocarbon feedstock, including a stage a) of distillation (D1) in which a tail product (Q1) is obtained via a line 3 and a head product (T1) via a line 2, a stage b) of liquid/liquid extraction (LE) with the aid of a solvent (S1) in which an extract (E1) (line 6) and a raffinate (R1), (line 5) are obtained from the product (Q1), a stage c) of separation (D2) of the raffinate (R1) making it possible to obtain via a line 7 a product (Q2) impoverished in solvent (S1) and a stage d) of hydrotreatment (HDS) in which the mixture of the products (T1) and (Q2) is treated in hydrotreatment conditions under a partial hydrogen pressure lower than 10 megapascals and a product (P), is obtained (line 9) which has improved qualities and contains less than 500 ppm by weight of sulphur. According to a particular embodiment the extract (E1) (line 6) is distilled so as to obtain via a line 11 a tail product (Q3) which is subsequently sent to a hydrotreatment zone so as to obtain via a line 12 a product (P') containing less than 0.3% by weight of sulphur. The solvent (S1) recovered at the head of the distillations is recycled to the extraction stage b). <IMAGE>
