Abstract
A method for monitoring a FCC catalyst injection system is provided. In one embodiment of the invention, the method includes automatically updating a catalyst available inventory information in a digital memory device in response to a catalyst usage event. A sufficiency of the updated catalyst available inventory is automatically determined. A re-supply action is then taken in response to a determination of insufficient catalyst available inventory. The method is repeated for each catalyst usage event.
