Wireless monitoring and profiling of reactor conditions using plurality of sensor-enabled rfid tags and multiple transceivers

A method of wirelessly monitoring and profiling process conditions within a reactor vessel, wherein said method comprises:

• providing said reactor vessel that defines a reaction zone, wherein within said reaction zone is a catalyst bed, comprising catalyst particles, and a plurality of sensor-enabled RFID tags disposed within said catalyst bed;
• wherein each of said sensor-enabled RFID tags of said plurality is encoded with an unique non-variable identification code and is further configured to measure a surrounding condition within said catalyst bed that is associated with said sensor-enabled RFID tag and to transmit responsive to an interrogation signal a responsive signal that includes information representative of said unique non-variable identification code and said surrounding condition associated therewith;
• transmitting by a first RFID reader (transceiver) antenna a first interrogation signal that is received by each of said sensor-enabled RFID tags;
• in response to receiving said first interrogation signal, each of said sensor-enabled RFID tags transmits its first associated RFID transponder signal received by said first RFID reader antenna that includes information representing its unique non-variable identification code and surrounding condition that is associated with said sensor-enabled RFID tag;
• receiving by said first RFID reader (transceiver) antenna said first associated RFID transponder signals;
• transmitting by a second RFID transceiver antenna a second interrogation signal that received by each of said sensor-enabled RFID tags;
• in response to receiving said second interrogation signal, each of said sensor-enabled RFID tags transmits its second associated RFID transponder signal received by said second RFID reader antenna that includes information representing its unique non-variable identification code and surrounding condition that is associated with said sensor-enabled RFID tag;
• receiving by said second RFID transceiver antenna said second associated RFID transponder signals;
• transmitting by a third RFID transceiver antenna a third interrogation signal that received by each of said sensor-enabled RFID tags;
• in response to receiving said third interrogation signal, each of said sensor-enabled RFID tags transmits its third associated RFID transponder signal received by said third RFID reader antenna that includes information representing its unique non-variable identification code and surrounding condition that is associated with said sensor-enabled RFID tag;
• receiving by said third RFID transceiver antenna said third associated RFID transponder signals;
• and
• processing said first associated RFID transponder signals, said second associated RFID transponder signals, and said third associated RFID transponder signals;
• whereby conditions throughout said reaction zone can be determined and profiled.
