Abstract
A method and apparatus for metering catalyst to a fluid catalytic cracking catalyst unit are provided. In one embodiment, an apparatus for metering catalyst to a fluid catalytic cracking catalyst unit includes a low pressure storage vessel coupled to a pressure vessel by a metering device. A controller is provided to control catalyst transfers between the storage and pressure vessels. The control is configured to facilitate event and catalyst inventory information with local and remote devices.
