A method for monitoring a FCC catalyst injection system is provided. One embodiment of the invention includes steps for determining an occurrence of a pre-defined event and establishing communication between a control module of the injection system and a remote device in response to the event. In another embodiment of the invention, a method is described which entails the acquisition of data from the injection system by a plurality of sensors. After the data is obtained, it is subsequently stored in the memory device of the control module. Communication is then established between a remote device and the control module to transfer the data.

What is claimed is: 1. A method for monitoring a fluid catalytic cracking catalyst injection system, the method comprising: determining an occurrence of a predefined event associated with the fluid catalytic cracking catalyst injection system; establishing communication between a control module of the fluid catalytic cracking catalyst injection system and a remote device in response to the event, wherein the remote device is remote from the fluid catalytic cracking catalyst injection system; and wherein the step of establishing communication comprises transmitting information to the remote device in response to a predefined event; and information comprises automatically submitting a reorder request for catalyst if a catalyst inventory level is below a predefined threshold; and transmitting information relating to the event between the remote device and control module. 2. The method of claim 1, wherein the step of establishing communication with the control module further comprises: initiating communication with the remote device from the control module. 3. The method of claim 1, wherein the predefined event is a threshold dependent event. 4. The method of claim 3, wherein the threshold dependent event is at least one of a blocked or impeded discharge port, a pressure deviation in a storage vessel, a pressure deviation within the injection system, a pressure deviation within a pressure control system, a deviation in the flow of catalyst from the injection system, a deviation from a planned catalyst injection schedule, a temperature deviation within the storage vessel, or a temperature deviation within the injection system. 5. The method of claim 3, wherein the threshold dependent event is at least one of pressure fluctuations in the injection system, a manual change in a catalyst setpoint, fluctuations of the indicated weight in the vessel, raw weight sensor information, sensor drift, or a manual addition of catalyst. 6. The method of claim 1, wherein the predefined event is a threshold independent event. 7. The method of claim 6, wherein the threshold independent event is at least one of a loss of power in the injection system, a setpoint change, a manual injection of catalyst, a refilling of a storage vessel with catalyst, an unscheduled interruption of the injection process, a recalibration of the injection system, a malfunction of the controller, a failure of a sensor, a deviation from a planned catalyst addition, an injection system alarm, or a controller alarm condition. 8. The method of claim 1, wherein the remote device is operated by at least one of a site operator, a catalyst supplier, a site technician, or service technician. 9. A method for monitoring a fluid catalytic cracking catalyst injection system, the method comprising: storing data from the fluid catalytic cracking catalyst injection system in a memory device of a control module; establishing communication between the control module and at least one of a remote or a local device in response to a predefined protocol; wherein the predefined protocol further comprises an event sensed by at least one of the fluid catalytic cracking injection system or the control module and wherein the predefined protocol comprises an event which exceeds a threshold; and transmitting data from the memory device of the control module to the at least one of the remote or the local device. 10. The method of claim 9, wherein the threshold is a predefined number of event occurrences. 11. The method of claim 9, wherein the threshold is a range or a magnitude spectrum. 12. The method of claim 9, wherein the event is at least one of a blocked or impeded discharge port, a pressure deviation in the storage vessel, a pressure deviation within the injection system, a pressure deviation within the pressure control system, a deviation in the flow of catalyst from the injection system, a deviation from a planned catalyst injection schedule, a temperature deviation within the storage vessel, or a temperature deviation within the injection system. 13. The method of claim 9, wherein the event is at least one of a loss of power in the injection system, a setpoint change, a manual injection of catalyst, a refilling of a storage vessel with catalyst, an unscheduled interruption of the injection process, a recalibration of the injection system, a malfunction of the controller, a failure of a sensor, a deviation from a planned catalyst addition, an injection system alarm, or a controller alarm condition. 14. The method of claim 9, wherein the predefined protocol further comprises: establishing communication on a predefined schedule. 15. The method of claim 9, wherein the step of establishing communication further comprises: communicating with the at least one of the local or the remote device via a communication link; and wherein the step of transmitting data further comprises: transmitting injection system information. 16. The method of claim 15, wherein the injection system information further comprises at least one of an event log, a periodic status report, or diagnostic information of the injection system. 17. The method of claim 9, wherein the data comprises catalyst inventor information.
