| Research Abstract |
1. In order to select test points for erosion-corrosion of carbon steel pipes, a method was developed to predict the area with maximal shearing stress by use of computational fluid dynamics software.
2. In order to select test points for atmospheric corrosion of insulated pipes, a method was developed to predict corrosion rates by use of information obtained in the design stage, information obtained in the operation stage and information obtained from outlooks of insulations.
3. For the safety of chemical plants, safety design based on the concept of independent protection layers (IPLs) has been introduced in chemical/oil refinery industries. Risk assessment/safety design support system is proposed to develop integrated safety management environment for Chemical plants
4. A method based on support vector machine is proposed for fault detection in time series process data. Support vector machine is one of supervised leaning method. We studied how to use this method in fault detection and a

ssessed its potentiality by using real distillation column time series data.
5. In order to clear and localize the effect of equipment trouble, new methods of fault detection and diagnosis was developed by using weak components in noisy signals. Application of the methods to both simulation and real plant showed that the faults can be accurately detected and diagnosed.
6. A nonlinear modeling technique using historical data during normal operations, which is called DB (database) modeling, has been proposed in order to predict the normal states of a dynamic process. We reported the good results of predictions with the numerical experiments by use of the tank-pipeline system, PVC batch process and the boiler plant simulator.
7. Large parts of oscillations observed in chemical plants are caused by faults of sensors or actuators. In this research, the fault detection capability of the method using high order statistics was examined and analyzed. And a control algorithm to stabilize the control system with abnormal sensors or actuators was proposed. Less
