VACUUM POWERED ADDITION SYSTEM
First Claim
1. An addition system for an FCC unit, comprising:
- a container having a vent port, a fill port and an outlet;
a first eductor coupled to the outlet;
a sensor configured to detect a metric of material dispensed from the container through the eductor;
a valve controlling flow through the eductor; and
a controller coupled to the sensor and valve, the controller providing a control signal for regulating an operational state of the valve.

Abstract
An addition apparatus, a fluid catalytic cracking (FCC) system having an addition apparatus, and a method for adding material to an FCC unit are provided. In one embodiment, an addition system for an FCC unit includes a container, a first eductor and a sensor. The eductor is coupled to an outlet of the container. The sensor is configured to detect a metric of material dispensed from the container through the eductor. A valve is provided for controlling the flow through the eductor. A controller provides a control signal for regulating an operational state of the valve. In another embodiment, an FCC system having an addition system is provided. In yet another embodiment, a method for adding material to an FCC unit is provided.
