FIELD: chemical engineering. SUBSTANCE: conditioning of hydrocarbon liquids before fractionation thereof is accomplished by subjecting liquids to mechanical vibrations. For that aim, liquid is fed into rotor hollow and withdrawn therefrom into annular chamber between rotor and stator through a series of outlet holes and then is withdrawn from annular chamber. In this process, following relationships are observed: R = (1.05Е1.28)K, mm; ΔR = (1.05Е1.28)B, mm; and n = (3.6Е4.1)K-1,5•106, rpm, where R is radius of peripheral surface of rotor, ΔR radial dimension of annular chamber, n rotary speed of rotor, K number of outlet holes in rotor, and B integer between 1 and K/2. EFFECT: enhanced efficiency of conditioning and subsequent fractionation of hydrocarbon liquids. 5 cl, 4 dwg, 2 tbl
