REAL-TIME LEVEL MONITORING FOR FIXED BED CATALYST LOADING USING MULTIPLE LEVEL SENSORS

摘要

In various aspects, methods and systems are provided for monitoring catalyst bed levels using multiple sensors that are temporarily installed in a reactor during catalyst loading. The multiple sensors are able to take distance measurements at substantially the same time and at predetermined time intervals so as to provide a catalyst time profile. The catalyst time profile allows an operator monitor catalyst levels during and after catalyst loading. Once catalyst loading is completed, the multiple sensors are removed from the reactor.
