Visualization of the Factor of Transported-Catalyst Density Distribution Along the Length of Vertical Pipelines in Petroleum Gas Oil Cracking Units.

The problem of prompt speed and density profile mapping based on mathematical modeling of particle motion in the acceleration section of catalyst pneumotransport lines is discussed. An algorithm is developed to calculate the distribution of these parameters along the longitudinal coordinate of reactor-lifts to improve ergonomic efficiency of operation of reaction-regeneration systems used in oil refining and petrochemical industries.
