Abstract
Disclosed is a system and method for wirelessly monitoring process conditions within a reactor vessel. A sensor-enabled radio frequency identification tag is located within a catalyst bed of a vessel and used to measure various conditions within the vessel. The sensor-enabled RFID tag is wirelessly linked to a reader for transmitting interrogation signals and for receiving transponder signals from the sensor-enabled RFID tag that carry information representative of the measured condition.
Claims26
A system for wirelessly monitoring process conditions within a reactor vessel, wherein said system comprises:
- said reactor vessel that defines a reaction zone;
- wherein within said reaction zone is a catalyst bed, comprising catalyst particles, and wherein within said catalyst bed is an RFID sensor capable of sensing a reactor condition within said reaction zone, receiving an interrogation signal, and responsive to said interrogation signal, transmitting an RFID transponder signal that includes information representative of said reactor condition;
- and
- an RFID reader antenna that is wirelessly linked to said RFID sensor and capable of transmitting said interrogation signal and receiving said RFID transponder signal that is responsive to said interrogation signal.
A method of monitoring process conditions within a reactor vessel, wherein said method comprises:
- providing said reactor vessel that defines a reaction zone within which is a catalyst bed, comprising catalyst particles, which catalyst bed includes an RFID sensor that is wirelessly linked to an RFID reader antenna;
- transmitting by said RFID reader antenna an interrogation signal, which is received by said RFID sensor;
- and
- responsive to said interrogation signal, transmitting by said RFID sensor an RFID transponder signal that includes information representative of a reactor condition within said reaction zone and which is received by said RFID reader antenna.
