Ensuring uninterrupted Gas Chromatograph operations with innovative, high-performance filtration solutions
ADNOC Refining faced recurring challenges with Gas Chromatograph (GC) operations due to frequent replacement of gas cylinders and regulator wear-and-tear, resulting in downtime and operational concerns. Experts E & I stepped in to provide a comprehensive dual filtration solution for Nitrogen and Instrument Air across RR-I and RR-II, designed to maximize reliability, efficiency, and safety.
The analyzer employs Tunable Diode Laser (TDL) technology with Off-Axis Integrated Cavity Output Spectroscopy (OA-ICOS) to deliver continuous, high-accuracy measurement of H₂S. Housed in a Zone 1 SS316 three-sided shelter with sunshade, the system ensures operational safety and durability in the field. The package includes an integrated Pressure Reducing Station, a Secondary Sample Conditioning System, and sampling components crafted from Super Duplex Stainless Steel and Hastelloy to withstand corrosion and process variations. Heat-traced sample lines, monoblock DBB probe arrangements, and cylinder rack setups further guarantee stable and precise operation.
Throughout the project, the team overcame significant challenges, including ensuring full compliance with client specifications and industry standards, optimizing the sampling system for high-accuracy measurements despite fluctuating process conditions, and engineering the system for reliability under extreme environmental stresses.
The project culminated in the successful completion of the Integrated Factory Acceptance Test (IFAT) on 15th January 2025 at our Integration Facility in Musaffah, Abu Dhabi, followed by the on-time shipment of the fully integrated H₂S analyzer package to PDO in Oman. This achievement underscores Experts E & I’s ability to deliver complex analytical solutions that combine precision, safety, and operational excellence under demanding conditions.
