Purified Terephthalic Acid

To enhance the work efficiency and systematization degree of fault diagnosis for process production, an extension CBR fault diagnosis (ECFD) method is proposed in which the extension theory applies the formal model to expand the possibility of matter and explore the innovative principle, and the CBR technology provides the ways for solution based on the historical experiences. Considering the characters of the two technologies, some researches are made on the extension basic-element case-description, distance-based extension case-retrieval, and character difference-based extension case-revision for fault diagnosis. Taking the purified terephthalic acid (PTA) solvent system as an application example for fault diagnosis, the ECFD method is proved to be feasible and effective, which provides a new way for diagnosing the production faults accurately.

With the level of complexity of the products was higher and higher, as a technology which can accelerate the development process, process modeling has become the focus of the domestic and international scholars. This paper studies the association relationship between the components’ structure of product design, and introduces the hierarchical principle of the feedback mechanisms, and constructs a new process modeling method based on the global design method, which improve the ability of description of the process model and the flexibility of the new product’s design. Then this method is applied to the car spraying production line.
