Study Of Motion Of Agglomerates Through A Fluidized Bed, Muhammad Owais Iqbal Bhatti

Electronic Thesis and Dissertation Repository

Formation of agglomerates in Fluid Cokers^TM can cause operating problems, such as excessive shed fouling, which can lead to premature unit shut down. Better understanding of how agglomerates move through a fluidized bed can help improve the design and operation of Fluid Cokers^TM and minimize the risk of agglomerates reaching regions where they cause problems.

To identify key factors in agglomerates motion in a fluidized bed, a new two-dimensional (2D) Radioactive Particle Tracking (RPT) method was developed which tracks model agglomerates motion. In conjunction, a tribo-electric method was used to determine bubble flow distribution in the fluidized bed. …
