Abstract
A fluid coking operation for converting bitumen to lighter hydrocarbons can be controlled or monitored using a stripper fouling indicator to mitigate foulant accumulation on the sheds of the stripper within the lower section of the coker and avoid flooding. The stripper fouling indicator can be linked to the liquid carry-under to the stripper which can be correlated to certain measurable variables such as which feed nozzles are used for bitumen injection, solids circulation rate of the coke particles, and reactor temperature. The coking can be kept below the stripper fouling indicator to avoid flooding while operating with high yield and performance.
