Modeling of the influence of cavitation on petroleum hydrocarbon cracking

  • Published:
Chemistry and Technology of Fuels and Oils Aims and scope

It is shown that axial, radial, and peripheral velocities of feed material in centrifugal vortex chamber pronouncedly differ in magnitude. The full velocity is high and attains 43 m/sec on the vortex surface. It is concluded that the cavitation region must be on the vortex surface itself, where indeed cracking of hydrocarbons intensifies. The parameters of the cavitaiton region are determined from the static liquid pressure at all points of the cavitation apparatus. The distribution of static pressure of the liquid in the centrifugal vortex chamber has a complicated pattern: the cavitation region represents a hollow truncated cone, inside which occurs a cylindrical steam vortex. Formation of a turbulent layer expands the cavitation region, the shape and size of which are calculated from the parameters of a real centrifugal chamber.
