ABSTRACT:
A method and apparatus for monitoring catalyst requirements of a fluid catalytic cracking catalyst injection system is provided. In one embodiment, a method for monitoring catalyst requirements of a fluid catalytic cracking catalyst injection system includes the steps of communicating with a memory device of a control module of the catalyst injection system that is adapted to control the amount of catalyst injected into a fluid catalyst cracking unit and determining if catalyst inventory needs to be replenished. The method enables both suppliers and processors to remotely monitor inventory requirements and take appropriate action if inventories fall below a predefined level or reorder point.
