摘要: The vaporization ratios of the slurry at various temperature and partial pressure were
calculated with the group-contribution method, and then the phase state of the slurry in
the residue fluid catalytic cracking (RFCC) disengager was determined. This research could
provide some advices on how to select the technological conditions to decrease the coking
in the RFCC disengager. The oil gas temperature and the slurry partial pressure had
signifi-cant effects on the vaporization ratio of the slurry. Increasing the oil gas
temperature and reducing the slurry partial pressure could effectively slow down the coking
speed in the RFCC disengager. According to the calculation results, a correlation was
established to predict the vaporization ratio of the slurry under different operating
conditions.
