Review on chemical process fault detection and diagnosis

According to industry 4.0, modern factories are transforming into smart factories, which set higher requirements for fault detection and diagnosis (FDD) to enhance operating safety and manufacturing sustainability. This paper gives a brief review on the state-of-the-art and challenges of chemical process FDD. Since the applications of FDD to real chemical processes are few, recent researches mainly focus on solving practical problems. Furthermore, with the big data era coming, the automation of FDD in chemical processes would be realized.
