An experimental investigation to verify the practical applicability of the method of fault diagnosis based on the signed digraph was performed with the use of a chemical process pilot plant with two chemical reactors where gas-liquid exothermic reactions in the presence of solid catalyst take place. The object was to identify eleven different causes of failure. It was confirmed, as the consequence of the experiments, that the feasibility of applying the algorithm is promising with the condition that the sensors are allocated properly to assure the promptness and accuracy of diagnosis.
