Development Of A Cold Model Fuild Coker Pilot Plant, Jessica A. Godin
Electronic Thesis and Dissertation Repository
Fluid CokingTM is an upgrading process used to produce higher-value products from heavy hydrocarbons through thermal cracking. A Hot Pilot Plant is being designed for potential use to optimize commercial Fluid Cokers.
A Cold Model Fluid Coker was operated in this thesis to identify design limitations restricting operation at the required conditions. Design changes were implemented, and their impact on the system fluid dynamics were characterized. Successful operation of at required conditions was demonstrated.
Pressure measurements provided rapid feedback on potential issues. Models for bed expansion and entrainment flux were developed, which can be used to extrapolate to the …

Particle Entrainment Studies From Dry And Wet Bed, Saber Ayatollahi
Electronic Thesis and Dissertation Repository
During the Fluid Coking Process™ bitumen is sprayed into a fluidized bed of hot coke particles. The bitumen undergoes thermal cracking and is converted into gasses, condensable vapors, and solid coke, which deposits on the coke particles. These vapors rise through the vessel and result in entrainment of coke particles. Wet fine coke particles from the freeboard region enter the cyclone and contribute to the fouling of the Coker cyclones which can lead to the premature shut-down of Fluid Cokers.
The primary objective of this research is to determine how bed wetness affects entrainment.
First, a new fluidized bed was …
