Introduction

CFD Dispersion Modelling is an advanced simulation technique used to analyze the behavior of gas and vapor releases within complex Oil & Gas facilities.
Using Computational Fluid Dynamics (CFD), the study captures the influence of geometry, congestion, ventilation, and wind conditions on the dispersion of flammable and toxic gases – providing a highly realistic representation of how hazardous clouds form, spread, and accumulate.

Purpose

• Simulate dispersion of flammable and toxic gas releases under realistic conditions
• Assess the impact of facility layout, congestion, and ventilation on gas behavior
• Identify areas of gas accumulation and potential hazardous cloud formation
• Evaluate different release scenarios, weather conditions, and leak cases
• Provide detailed inputs for safety studies (e.g., HAC, QRA, Fire & Gas Mapping)

Outcomes

• Detailed gas concentration profiles and dispersion behavior over time
• Gas concentration profile
• Identification of accumulation zones and poorly ventilated areas
• Assessment of hazardous cloud extent and escalation potential
• Inputs for optimization of gas detector placement and coverage
• Support for Hazardous Area Classification (HAC) and QRA justification
• Recommendations for layout, ventilation, and risk mitigation measures
• High-quality visualizations and structured report for clear communication and decision-making
