NOVARGI GASCO De-ethanizer Fired Heater Burner Management System (BMS)

NOVARGI, a leader in process technology for the oil & gas industry, was tasked with the critical De-ethanizer Fired Heater for the GASCO Western Desert Gas Complex. Partnering with MISC, they implemented a state-of-the-art, safety-certified Burner Management System (BMS) to ensure the highest levels of operational safety and control integrity for the fired heater operation.

Project Scope

• Design and supply of a dual-tiered safety system: a Control BMS (BMS-C) for operational sequencing and a Safety BMS (BMS-S) for personnel and equipment protection.
• Implementation of two separate, high-availability redundant Siemens S7-400FH controllers; the BMS-C certified for SIL2 and the BMS-S certified for SIL3.
• Supply of distributed I/O stations using Siemens ET200M technology with redundant and simplex fail-safe modules, comprehensive intrinsic safety (IS) barriers, and a TP1500 Comfort HMI for local monitoring.
• Provision of a full engineering workstation, comprehensive software engineering, and extensive FAT services.

Key Benefits

• Uncompromising safety assurance through a dedicated, SIL3-certified safety system (BMS-S) architected for maximum fault tolerance and reliability.
• High operational availability and control precision with a separate, SIL2-certified control system (BMS-C) managing complex burner sequences.
• Full compliance with international safety standards (IEC 61508, ISO 13849) for critical process applications.
• Enhanced diagnostic capabilities and system maintainability with hot-swappable modules and comprehensive documentation.

Outcome

MISC delivered a fault-tolerant, safety-certified automation solution that empowered NOVARGI and GASCO to operate the De-ethanizer Fired Heater with the utmost confidence. This project established a benchmark for safety in critical oil and gas heating applications, protecting both plant assets and personnel while ensuring continuous and reliable process operation.

Technology used:

Two Siemens S7-400FH redundant controllers & ET200M I/O (SIL2 and SIL3 Certified)
