HAZOP Scribing of Acid Gas Removal Unit (AGRU) at KGOC
Client Overview: HSE Risk Management Services (HSE-RMS) was engaged to provide scribing support for the Hazard and Operability (HAZOP) Study of the Acid Gas Removal Unit (AGRU) at Kuwait Gulf Oil Company (KGOC). The objective was to ensure systematic, accurate, and standards-compliant documentation of all HAZOP proceedings, including deviations, risks, and recommendations to enhance process safety and operability.
Process Technology Overview: The AGRU is designed to remove acid gases (primarily H₂S and CO₂) from feed gas using an amine absorption-regeneration system. The unit consists of multiple interconnected sections:
- Feed Gas Handling & Absorption Section
- Rich Amine Handling Section
- Wash Water System
- Lean Amine Circulation System
- Regeneration Section
- Storage & Utility Systems
HAZOP Concept: The HAZOP study is a structured and systematic technique used to identify potential hazards and operability issues in process systems. It involves a multidisciplinary team analyzing deviations from design intent using guidewords applied to process parameters.
In this assignment, HSE-RMS was responsible for real-time scribing, ensuring all discussions, deviations, causes, consequences, safeguards, and recommendations were accurately recorded.
HAZOP Methodology: The HAZOP study was conducted in accordance with:
- Shell DEP 80.00.00.15 – Gen (Hazard and Operability Study guideline)
- KOC Recommended Practice KOC-L-017 for HAZOP Studies
The methodology followed a systematic, team-based approach involving detailed examination of process deviations using guidewords applied to key parameters such as flow, pressure, temperature, and composition.
