FIELD: petrochemical processes. SUBSTANCE: hydrocarbon mixture and heat carrier, prior to come into contact with each other in mixing space, are made follow curvilinear trajectories to create, in mixing space, local zones with considerably lowered total and partial pressures. Then, combined hydrocarbon-heat carrier flow is subjected to dispersing followed by separation of products. EFFECT: reduced power consumption and diminished number of complex process equipment. 3 cl, 2 dwg
