Nitrogen Plant Process Control DCS

AMOC Nitrogen Plant Automation Migration

Alexandria Mineral Oils Company (AMOC) partnered with MISC to modernize and future-proof the automation system of its Nitrogen Plant. The existing Siemens S5 controllers and operator workstations had become obsolete, creating challenges for reliability, scalability, and long-term maintainability.

Project Scope

• Migration from Siemens S5 to Siemens PCS 7 DCS
• Replacement of old controllers with new PCS 7 controllers
• Deployment of redundant ET200M I/O racks with full I/O and network redundancy
• Supply and commissioning of modern Operator Workstations (OWS) with advanced control and monitoring capabilities

Key Benefits

• Transition to a cutting-edge DCS platform (PCS 7), securing long-term support and scalability
• Full system redundancy at controller, I/O, and network levels for maximum reliability and uptime
• Improved operator control and visibility through advanced OWS with alarms, diagnostics, and trending features
• Extended lifecycle of critical assets with modern, standardized Siemens technology
• Enhanced plant safety, reliability, and efficiency through integrated automation and monitoring

Outcome

Through this migration, MISC enabled AQFC to replace obsolete systems with a future-ready PCS 7 automation platform, ensuring secure, efficient, and uninterrupted operation of the Nitrogen Plant for years to come.

Technology used:

* PCS7
