Mitigation Of Fluid Coker Cyclone Fouling With Consideration To Reactor Performance, Andrew J. Heaslip
Mitigation Of Fluid Coker Cyclone Fouling With Consideration To Reactor Performance, Andrew J. Heaslip
Electronic Thesis and Dissertation Repository
Fluid Coking is a continuous process to thermally upgrade heavy hydrocarbons into lighter, higher-value products. Fouling of the cyclones in commercial Fluid Coker reactors significantly reduces unit runtimes. The main objective of this thesis is to improve unit reliability by identifying process levers that can mitigate against this phenomenon while minimizing reductions in product quality. This thesis expanded a previous freeboard region model to consider vapour phase cracking and adsorption and developed a novel reactor region model to consider the impact of liquid and vapour phase cracking, vapour-liquid equilibrium, and residence time distribution on product composition. By changing the temperature …
