Abstract
The main aim behind this paper is to develop, design and implement on-line fault diagnosis on real-time industrial processes with suitable performance measures. For this purpose, the system is modeled using Petri nets. The system considered for study here is the Sulphur recovery unit (SRU) of Chennai Petroleum Corporation Ltd (CPCL), Chennai. SRU is one of the most important units in the refining process for extraction and removal of sulphur from the products in-order to improve the efficiency. So, in this paper, the sub-units, valve sequence system of Main clause recovery concept (MCRC) converters and vaporized liquefied petroleum gas (LPG) header system of SRU are considered for study. Fault diagnosis algorithms are being developed based on the above idea along with evaluation of appropriate performance measures.
