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.
Claims17
Apparatus for loading catalyst to a fluid catalyst cracking unit, comprising:
- a pressure vessel having a single output adapted for coupling to a fluid catalyst cracking unit;
- a plurality of separate catalyst storage containers coupled to the vessel, the containers maintained at a low pressure;
- and
- a pressure control system configured to selectively pressurize of vessel to a high pressure.
Apparatus for loading catalyst to a fluid catalyst cracking unit, comprising:
- an injection apparatus having an outlet port for coupling to a fluid catalyst cracking unit (FCCU);
- a plurality of catalyst storage regions coupled to the injection apparatus;
- and
- a change in weight measuring system interfaced with the injection apparatus configured to determine an amount of catalyst delivered through the injection apparatus from a selected one of the catalyst storage regions to the FCCU.
A method of providing catalyst to a fluid catalyst cracking unit, comprising:
- providing an injection apparatus having a plurality of separate catalyst storage regions, the injection apparatus coupled to a fluid catalyst cracking unit (FCCU);
- delivering catalyst from a selected one of the catalyst storage regions through the injection apparatus to the FCCU;
- and
- determining an amount of catalyst from each region delivered to the FCCU through the injection apparatus.
A method of providing catalyst to a fluid catalyst cracking unit, comprising:
- selectively flowing catalyst from a first catalyst storage region to a vessel having at least a second catalyst storage region coupled thereto;
- pressurizing the vessel;
- and
- injecting catalyst from the pressurized vessel to a fluid catalyst cracking unit (FCCU).
A method of providing catalyst to a fluid catalyst cracking unit, comprising:
- providing a change in weight measuring system coupled to a fluid catalyst cracking unit (FCCU);
- automatically providing catalyst to the FCCU through the weight measuring system selectively from a plurality of catalyst storage regions.
