The control effect of bottom oil slurry system of fractionator in the fluid catalytic cracking unit （FCCU） is of great significance for the FCCU＇s smooth and safe operation. Many large FCCUs have been constructed in China in recent years. Some adopt domestic technologies and others adopt foreign technology packages with varies types of control scheme for bottom slurry oil system of these FCCU fractionators. Three typical control schemes are summarized. In recent years, they have been applied in the bottom slurry oil system of fractionator on new domestic FCCU. The properties are described, briefly compared and evaluated for each individual control scheme. On this basis, their applicable situations have been put forward for designer to design reasonable control scheme for each individual project based on characteristics to reach best control effect.
