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.
Claims16
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.
Apparatus for metering catalyst in a fluid catalytic cracking catalyst injection system, comprising:
- a low pressure storage vessel;
- a pressure vessel having an outlet adapted to be coupled to a fluid catalytic cracking unit;
- a control valve coupling a discharge port in the storage vessel to an inlet port of the pressure vessel;
- and
- at least one load cell adapted to provide a metric indicative of a weight of the storage vessel.
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 and having an outlet adapted to be coupled to a fluid catalytic cracking unit and an inlet, the pressure vessel selectively isolatable from the storage vessel;
- and
- a metering device coupling the storage vessel to the inlet of the pressure vessel.
