METHOD FOR THE REMOVAL OF AROMATICS FROM PETROLEUM FRACTIONS

摘要

A method for the removal of aromatics from a petroleum fraction in a dearomatised hydrocarbon fluid with a sulphur content less than or equal to 5 ppm and an aromatic compound content less than or equal to 300 ppm, said hydrocarbon fluid having a boiling point of between 100 and 400°C according to the ASTM D86 standard and a distillation range defined by the difference between the initial boiling point (IBP) and the final boiling point (FBP) determined according to the ASTM D86 standard not exceeding 80°C, said method comprising at least one cycle for the removal of aromatics implementing a mixture of the petroleum fraction with one or more inert and lightweight diluents having a distillation range not exceeding 80°C.
