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 …

Cluster Fluid Dynamics In Down Flow Reactors: Experimental And Modeling Study, Angel Virgilio Lanza Soto
Electronic Thesis and Dissertation Repository
Gas–solid concurrent downers possess unique features when compared to other gas–solid systems. Establishing their fluid dynamic properties requires both experimental measurements of gas-solid flow properties and computational modeling.
Measuring gas-solid flow properties such as cluster solid concentrations, individual cluster slip velocities, and cluster sizes, involves the use of specialized optical equipment, as well as a rigorous data analysis methodology. In addition, the modeling of the fluid dynamics of gas-solid flows in downer units offers special challenges such as establishing a proper drag model, cluster configuration and sizes, sphericity, boundary conditions, among other issues.
In this PhD dissertation, the fluid dynamics …
