1. Apparatus for metering catalyst in a fluid catalytic cracking catalyst injection system, comprising:
- a low pressure storage vessel;
a pressure vessel rigidly coupled to a supporting surface having an outlet adapted to be coupled to a fluid catalytic cracking unit and an inlet;
a pressure control device coupled to the pressure vessel and configured to selectively pressurize the pressure vessel relative to the storage vessel; and
a metering device coupling the storage vessel to the inlet of the pressure vessel.

Abstract
A method and apparatus for metering catalyst in a fluid catalytic cracking catalyst injection system are provided. In one embodiment, apparatus for metering catalyst in a fluid catalytic cracking catalyst injection system includes a low pressure storage vessel coupled to a pressure vessel that defines a high pressure side of the apparatus, where the determination of the amount of catalyst transferred is made on the low pressure side of the apparatus.
