Abstract
The invention is a multi-catalyst injection system. In one embodiment, the system comprises a plurality of catalyst storage regions associated with a vessel and a metering device associated with the vessel. The metering device is configured to provide a metric indicative of an amount of catalyst dispensed from a selected one of the catalyst storage regions.
Claims21
Apparatus for loading catalyst to a fluid catalyst cracking unit, comprising:
- a vessel;
- a plurality of catalyst storage regions associated with the vessel;
- a metering device associated with the vessel and configured to provided a metric indicative of an amount of catalyst dispensed from a selected one of the catalyst storage regions.
Apparatus for loading catalyst to a fluid catalyst cracking unit, comprising:
- a vessel configured to selectively provide a plurality of catalysts to a fluid catalyst cracking unit (FCCU), the vessel having a plurality of catalyst inlet ports for loading different catalysts into the vessel;
- a metering system configured to determine amounts of catalysts welded to the FCCU;
- a controller coupled to the metering system and containing instructions that, when executed, causes a selective one of the plurality of catalysts to be delivered to the FCCU through the vessel.
A method of providing catalyst to a fluid catalyst cracking unit, comprising:
- providing an injection apparatus having a plurality of separate catalyst storage regions to a fluid catalyst cracking unit (FCCU);
- selectively delivering catalyst through the injection apparatus to the FCCU;
- and
- determining an amount of catalyst delivered to the FCCU through the injection apparatus.
A method of providing catalyst to a fluid catalyst cracking unit, comprising:
- flowing a plurality of catalysts into an injection apparatus coupled to a fluid catalyst cracking unit (FCCU);
- and
- pressurizing the injection apparatus prior to injecting a selected one of the catalysts to the 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 system selectively from a plurality of catalyst storage regions.
