Computational fluid dynamics (CFD) of crude oil separator with coalescer |
| 초록 |
The present study proposes an Eulerian air-oil-water three-phase computational fluid dynamics (CFD) model for predicting the separation efficiency and fluid behaviors in a bench-scale separator with coalescer. The k-ɛ dispersed turbulence model is used. The air-phase is considered continuous, while oil and water phases are supposed as mono-dispersed phases. The experimental observation confirmed the importance of liquid exit pressure on controlling the liquid level of the separator that will change the separation efficiency. The CFD simulation found that the exit pressures at 6.3 kPa and 5.1 kPa for water and oil, respectively, are suitable for maintaining a liquid level of 25 cm with a good separation efficiency. The vertical velocities of water and oil in the horizontal center line were analyzed at different vertical positions. The mean residence time obtained from the CFD simulation was about 15 and 16 min for water and oil, respectively. The predicted oil separation efficiency (99.85%) agreed well with experimental data (99.96 %). |
