Abstract
A process for the fractional distillation of crude oil, which comprises the steps of: feeding a continuous current of crude oil at 310 400.degree. C. into a turbomixer comprising a tubular cylindrical body (1) provided with a rotor (9) formed with helically oriented paddles (10) and rotatably supported inside the body, along with a continuous current of steam; subjecting both currents to the mechanical action of the paddled rotor (9), so as to create a thin tubular dynamic turbulent layer, which is discharged and fed continuously into a fractioning column, at a predetermined height level in the column, to produce an upward-flowing vapor current and a downward-flowing liquid current therein; and optionally discharging the downward-flowing liquid current continuously from the column bottom, and feeding it continuously into the turbomixer in the same direction as the crude oil current.
