efficient production. Within the company’s quality control (QC) activity, four different production groups received prizes for their efforts in using this package to automate manual procedures. When SPCL upgraded from CENTUM CS to CENTUM CS 3000, it extended the use of Exapilot to all other operations throughout the plant, including the startup and shutdown of three oxidation reactors. Prior to the introduction of Exapilot, emergency shutdowns of the reactors were particularly labor intensive, requiring operators to carry out many different manual operations such as ramping down the set points for the reactor temperature controller, opening and shutting valves, transferring intermediate chemicals to temporary storage tanks, and carrying out various other recovery processes. Similarly, many different manual operations were necessary to start up the reactors. Exapilot automates the execution of all these procedures and allows operators to monitor and confirm these operations while they are in progress. Safer operation and greater consistency in product quality was available now.Another very labor intensive operation involved the treatment of the plant’s wastewater. The filters used in the separation process need to be cleaned by means of carbon purification, this takes up to eight hours, needs to be done two or three times per day, and requires the manipulation of 15 valves per filter. This process has also been automated using Exapilot. As a result, Exapilot reduces operator work load.Customer SatisfactionJun Ho Hwang of Associate Daesan Maintenance Team, commented, “First of all, our company pays careful attention to quality control, and every department is striving to make improvements in this area. Our group aims to improve efficiency by automating manual procedures as much as possible. This helps to ensure safe operations 24/7, to reduce operator work load, and to ensure the consistent product quality.”He added, “All of our operations are managed by Exapilot. Only the interlocks have been implemented through the CENTUM CS 3000 system. APC software and the Exaplog package have also been introduced to bring added improvements in efficiency. Maintenance engineers have assigned a total of 160 internal switches for Exapilot configuration, and all the logic is implemented by the skilled operators.So the know-how from the skilled operators is transferred by Exapilot to younger operators. Our central control room is quiet and our production operations have been going smoothly.” Central control room (CENTUM CS 3000 and Exapilot displays) Assignment of the Internal switches for Exapilot Filter purification by ExapilotSuccess Story Collection10Samsung Petrochemical Co.
