Hydrodynamic activation of heavy oil residues

Objectives. Recently, there has been a tendency to increase the volume of high-viscosity heavy oils in total oil produced. The processing these requires new technological approaches. This task is closely related need depth refining. Among approaches proposed solve problems, mechanochemical activation, which based on cavitation effect produced by ultrasonic or hydrodynamic methods, suggested. study evaluated effects increasing Methods. Straight-run and “secondary” products were used as raw materials: vacuum gas oil, catalytic cracking fuel oil. Activation was carried out high-pressure disintegrator. principle operation compress product then pass it through diffuser. When passed diffuser, sharp pressure release atmospheric pressure, caused flow. gradient diffuser number cycles ranged from 20 50 MPa 1 10, respectively. density, refractive index, fractional composition petroleum determined using standard generally accepted methods. Results. paper reports influence activation their physical chemical characteristics. An leads decrease boiling point density an yield fractions that boil off below 400 °C. with points 400–480 °C remainder reduced. index up 480 decreased, residue increased. (an products) increased cycles. Conclusions . changes point, 5. Increasing more than five had little additional effect. initial product. average molecular weight estimated densities individual products. calculation confirmed assumption regarding course reactions under indicates compaction processes.
