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.
Claims28
A system for wirelessly monitoring process conditions within a reactor vessel, wherein the system comprises:
- the reactor vessel that defines a reaction zone;
- wherein within the reaction zone is a catalyst bed comprising catalyst particles, and wherein within the catalyst bed is an RFID sensor configured to sense a reactor condition within the reaction zone, receive an interrogation signal, and in response to the interrogation signal, transmit an RFID transponder signal that includes information representative of the reactor condition;
- and
- an RFID reader antenna that is wirelessly linked to the RFID sensor and configured to transmit the interrogation signal and receive the RFID transponder signal that is responsive to the interrogation signal.
A method of monitoring process conditions within a reactor vessel, wherein the method comprises:
- providing the reactor vessel that defines a reaction zone within which is a catalyst bed comprising catalyst particles and an RFID sensor that is wirelessly linked to an RFID reader antenna;
- transmitting by the RFID reader antenna an interrogation signal, which is received by the RFID sensor;
- and
- transmitting by the RFID sensor, in response to the interrogation signal, an RFID transponder signal that includes information representative of a reactor condition within the reaction zone and which is received by the RFID reader antenna.
