Abstract
Abstract
Fluid CokingTM is a process that upgrades Alberta’s heavy oil. The recycle stream in the process contains unwanted fines which could affect the interaction between the liquid feed and the bed particles and the tendency to form agglomerates. Agglomeration leads to lower product yields and vessel damage.
The impacts of slurry solids on spray stability and angle were measured in open air while the impacts on agglomerate stability and liquid distribution were studied in a fluidized bed. Particle properties were varied to understand the impact of the solids on agglomerates.
In open air, it was observed that the presence of solids had a negligible impact on spray behavior. Within the fluidized bed, changing the concentration of injected solids produced a significant effect on agglomerate stability and liquid distribution.
By changing the properties of the slurry fines, it was determined that the injection of solids resulted in a filler effect within the agglomerates: the fines strengthened the agglomerates.
