FCC CATALYST INJECTION SYSTEM HAVING CLOSED LOOP CONTROL

WIPO Patent Application WO2004105930

A3

A system and method for injecting catalyst into a fluid catalyst cracking (FCC) unit (202) is provided. In one embodiment, a system for injecting catalyst into a FCC unit includes at least one catalyst injection apparatus (206A) for providing catalyst to a fluid catalyst cracking unit (202), at least one sensor (224) adapted to provide a metric indicative of the composition of a product stream produced in the fluid catalyst cracking unit, and a controller (204) coupled to the sensor (224), for controlling the additions made by the catalyst injection system (206A) in response to the metric provided by the sensor (224). Another embodiment of the invention comprises a method for injecting catalyst from a catalyst injection system into a FCC unit that includes the steps of dispensing catalyst for a catalyst injection system into a fluid catalytic cracking unit, sensing an output in the fluid catalytic cracking unit, and automatically adjusting the amount of catalyst dispensed in response to the at least one sensed metric.
