Title:
WIRELESS MONITORING AND PROFILING OF REACTOR CONDITIONS USING PLURALITY OF SENSOR-ENABLED RFID TAGS AND MULTIPLE TRANSCEIVERS
Document Type and Number:
WIPO Patent Application WO/2019/139953
Kind Code:
A1
Abstract:
Disclosed is a system and method for wirelessly monitoring 5 process conditions within a reactor vessel. A plurality of sensor-enabled radio frequency identification (RFID) tags are disposed at unspecified or random locations throughout a catalyst bed of a vessel and are used to measure various conditions within the vessel. The sensor-enabled RFID tags are encoded with individual identification codes and are wirelessly linked to multiple 10 transceivers. The use of multiple transceivers allows for the application of triangulation methods to identify the location of each of the sensor-enabled RFID tags in threedimensional space and for the interrogation of each sensor-enabled RFID tag to receive responsive transponder signals that carry information representative of the sensed condition within the reactor.
