PT. Pertamina, which provides a reliable supply of energy for Indonesia’s industries and everyday life, revamped its aging DCS while the plant was shut down for routine maintenance. This method enabled the company to modernize the system while minimizing production loss during system renewal. Going forward, the company is planning to implement energy-saving measures.
The problem of renewing a DCS in operation for 20 years
PT. Pertamina was established in 1957 by the Indonesian government to provide stable supplies of oil and gas. In November 2001 the company was privatized with the aim to more effectively utilize energy resources; today, it has grown into Indonesia’s largest oil and gas enterprise. Pertamina owns oil and natural gas reserves across Indonesia and handles a vast array of oil-related products; including the production of various fuels from gasoline and light and crude oils through to liquefied natural gas and jet fuel, and the production of non-fuel products such as asphalt and coke, and petrochemical products as benzene and paraxylene. Already well known throughout Indonesia, Pertamina is gaining recognition overseas. And in a bid to become a leading enterprise representing Southeast Asia, the company is meeting the challenge of changing mindsets internally to tackle cost reduction, environmental measures, and other initiatives.
Pertamina currently operates six oil refineries, of which Refinery Unit IV at Cilacap is positioned as a strategically important production base. It boasts a production capacity of 348,000 barrels/day, and produces fuels such as gasoline, avtur, diesel, and LPG, paraxylene, lube base oil, and sulfur.
Mr. Sundhoro R said: “Cilacap’s Refinery Unit IV consists of two oil refining plants that began operation in 1971 and 1983, and a paraxylene plant that started operation in 1990. Our challenge was updating the existing DCS*1 used for operation and management of the paraxylene plant. So we asked several vendors to draw up proposals for this project.”
These case studies were published in the 2012 Vol.4 issue of the azbil Group's corporate magazine, azbil.
