|Diagnostic Tools for Process Industry|
A project to develop failure diagnosis, prediction and maintenance tools for typical process industry equipment, undertaken by the Tsinghua University, has recently passed the verification check. Researchers have worked out the proprietary oil pipeline failure diagnosis system, and intelligent health diagnosis system for aluminum electrobath. Both diagnosis systems are able to detect or predict equipment abnormalities or failures that may cause heavy economic losses or security accidents, helping users to keep huge potential economic returns. The oil pipeline failure diagnosis system is designed with major functions of an SCADA system, having real-time automatic detecting and positioning functions for possible pipeline leakage. The intelligent health diagnosis system for aluminum electrobath can effectively predict anticathode effects of aluminum electrobath, a desirable tool for monitoring and controlling anticathode effects, and playing a positive role in energy efficiency enhancement and product quality assurance. In addition, the technology creates a ground for developing and using similar diagnosis systems for the generic equipment in process industry.The oil pipeline failure diagnosis system has so far found successful applications in Shaan'xi Yanchang Oilfield Administration and Shengli Oilfields. The intelligent health diagnosis system for aluminum electrobath has been used on a trial basis in both Gansu Baiyin Aluminum Works, and Henan Shenhuo Aluminum Works.
