(IRPC) in Rayong, Thailand has a refinery (215,000 b/d) as well as several petrochemical plants that produce chemicals such as olefins (360,000 t/y) and aromatics that are used as feedstock at various types of plastics plants. One of these petrochemical plants produces 140,000 t/y of acrylonitrile butadiene styrene (ABS). Although this plant had experienced no major problems with its CENTUM-XL process control system during the 19 years that it was in use, IRPC decided to upgrade to the latest technology when Yokogawa announced the end of service for CENTUM-XL. To control complex production operations in a total of 17 batch reactors at this ABS plant, Yokogawa Thailand installed the CENTUM CS 3000 Integrated Production Control System together with CCTV equipment, a plant information management system (PIMS), the Exaplog Event Analysis Package, and the CS Batch 3000 package.About ABSThis material is a terpolymer of acrylonitrile, butadiene, and styrene. Usual compositions are about half styrene with the balance divided between butadiene and acrylonitrile. Considerable variation is possible resulting in many different grades of acrylonitrile butadiene styrene with a wide range of features and applications. In addition, many blends with other materials such as polyvinylchloride, polycarbonates and polysulfones have been developed. Acrylonitrile butadiene styrene materials can be processed by any of the standard thermoplastic processing methods. Chemical (Base Chemical, Fertilizer, Petrochemical)41Success Story Collection
