Project Overview
- Target: Verify accurate sizing and optimize oxygen injection nozzles for a Monoethylene Glycol (MEG) unit capacity expansion project at the Marvarid Petrochemical Complex.
- Approach: Conducted 3D turbulent gas mixing CFD simulations across extreme operating envelope thresholds (Start of Cycle and End of Cycle catalyst conditions) and validated models using plant operational data.
- Achievements: Demonstrated a capacity enhancement that increased mixing tube outlet velocity by 7 m/s while maintaining a robust 99% oxygen mass fraction uniformity index at the outlet and improving velocity uniformity by 3.5%.
