文摘
- •
Application of surfactant foams for mobility control and LNAPL recovery
- •
Used layered sandbox with p-xylene as LNAPL and Ammonyx Lo at 0.1% (w/w)
- •
With foam, a better sweep was achieved, indicating better mobility control
- •
A negligible p-xylene residual saturation was reached following foam injection
- •
Recovery was by mobilization (19%), dissolution (16%) and volatilization (65%)
