Yokogawa Electric Corporation’s subsidiary, PT Yokogawa Indonesia, has received an order from PT Chandra Asri Petrochemical Tbk (CAP) to replace the legacy distributed control system (DCS) and safety instrumented system (SIS) at the company’s ethylene and polyethylene plant in Cilegon, which is in western Java’s Banten Province.
This CAP facility is Indonesia’s premier petrochemical plant, incorporating state-of-the-art technology and supporting facilities. The plant’s naphtha cracker produces high-quality ethylene, propylene, crude C4 and pyrolysis gasoline (Py-gas) for the Indonesian as well as regional export markets. These are basic petrochemical products obtained from the distillation of crude oil. Crude C4 includes butane and butylene that have four carbon atoms per molecule.
The CAP subsidiary PT Styrindo Mono Indonesia (SMI) will also replace the legacy DCS at the company’s styrene monomer plant, which is about 40km from the CAP plant and has an annual output of 340,000MT.
Yokogawa Indonesia will provide the latest CENTUM(R) VP DCS and ProSafe-RS SIS along with engineering, installation, commissioning, and engineering and operator training. These projects are expected to take 10 months to finish.
Key factors in the CAP Group’s selection of Yokogawa for these replacement projects were the high reliability and global track record of Yokogawa’s CENTUM VP and ProSafe-RS platforms, the close project support made possible by global co-operation between Yokogawa Indonesia and Yokogawa Engineering Asia Pte which is responsible for the Yokogawa Group’s operations in Asia and the company’s global maintenance and service network.
