Invensys Process Systems Brazil will also provide a wide range of services, including configuration, testing, commissioning, start-up and training.
In addition, for the Paulinia refinery, Invensys is providing all basic and detailed engineering services throughout the safety systems project.
The Invensys solutions were selected due to the reliability and inherent high availability of the Triconex TMR design, as well as extensive Invensys support dedicated to Petrobras.
Duque de Caxias Refinery has installed capacity of 242,000 barrels per day, and produces lubricants, gasoline, diesel fuel, jet fuel, bunker oil, as part of a line of 52 different products.
Paulinia Refinery has an installed capacity of 360,000 barrels per day, producing mainly diesel, gasoline, naphtha, kerosene, coke, asphalt and turpentine.
The Triconex TMR technology employs three isolated, parallel control systems and extensive diagnostics integrated into one system.
The system uses two-out-of-three voting to provide high-integrity, error-free, uninterrupted process operation.
The TMR architecture eliminates any single point of failure and enables on-line maintenance, on-line programming downloads, self-calibration and fault localisation.
