Samsung Petrochemical Co. Ltd.Introduction of Exapilot Reduces Workload, Enhances Safety, and Ensures Consistent Product QualityExecutive SummarySamsung Petrochemical Co. Ltd. (SPCL), a major Korean petrochemical company, produces 700,000 tons per year of purified terephthalic acid (PTA) at its Daesan plant. PTA, a white powder substance that is produced by oxidizing and refining para-xylene, is a precursor to polyethylene terephthalate (PET), a polyester material that has excellent thermal resistance and wear resistance and is widely used as a substitute for natural cotton fibers and in film packaging, beverage bottles, tire cords, paints, adhesives, and other applications. As of 2010, global annual demand for PTA stood at 39 million tons, and is expected to continue growing by 7% a year until 2016. Growth is especially strong in Asia, particularly China and India. (Source from Petrochemical industries in ASIA 2013 issue) SPCL is striving to improve safety at this plant and wants to reduce operator workload and ensure consistent product quality by automating complex operations. To achieve these aims, Yokogawa Korea installed the Exapilot operation efficiency improvement package and integrated it with the plant’s existing CENTUM CS 3000 production control system. With these new systems in place, the SPCL plant is operating flawlessly. The Challenges and the SolutionsUp until 2000, SPCL was using the CENTUM CS DCS and an advanced process control (APC) package. Around this time, Exapilot was installed and used on a trial basis, as part of an effort to improve quality control in each department and ensure more Plant InformationLocation: Daesan, South KoreaOrder date:January 2012Completion:October 2012Overview of PTA production process9Success Story CollectionChemical (Fine & Specialty Chemical, Biofuel)& Pharmaceutical
