In Fluid Coking, heavy oil is sprayed into a fluidized bed of hot coke particles that provide heat for the reaction and vaporization of the products, using nozzles located at different radial and axial locations of the reactor. In industrial units, imperfect initial liquid-solid contact results in the formation of wet agglomerates, which have been shown to cause fouling of the stripper sheds.
This thesis aims to reduce agglomerate formation by modifying the bed hydrodynamics in the spray region by adjusting the initial fluidization gas distribution or using a baffle.
Experimental methods were developed to study local gas flow, solids …
