Mechanism-based deep learning for tray efficiency soft-sensing in distillation process
Reliability Engineering & System Safety(2022)
Abstract
•Online soft sensing of tray efficiency in distillation system is realized by deep learning method.•Mechanism model provides high-quality datasets for deep learning model.•Cluster analysis extracts typical working conditions to further improve the value density of training set.•Generalized extreme value distribution is used to assess the probability of tray anomalies.
