| Abstract: | Aiming at the main factors affecting the long term running of FCC slurry system and the coking and fouling problems occurred, countermeasures, such as modifying the flow scheme, optimizing the operating conditions including lowering the bottoms temperature and level of the fractionator and increasing the slurry linear velocity in the heat exchange system, together with adding antifoulant in the slurry, etc., were taken. These measures enabled the long term running of the slurry system. |
