Abstract: Aiming at complicated faults of chemical process, the ontology was introduced into the field of fault diagnosis for chemical process so as to create Chemical Process Fault Diagnosis Ontology (CPFDON). CPFDON consisted of two ontologies: process ontology was the conceptualized specification of chemical process; diagnosis ontology was the conceptualization of faults, interrelationships among faults, relationship between faults and unit operations. CPFDON could directly be used to create Diagnosis Knowledge Base, besides it could also be used as Medium Language to achieve diagnosis knowledge sharing among heterogeneous systems. Continuous Stirred Tank Reactor (CSTR) simulation study has proved that an effective diagnosis could be achieved by using CPFDON to represent the fault diagnosis knowledge of chemical process.
