Experimental investigation on light non-aqueous phase liquids removal from groundwater using steam injection technique

Groundwater pollution by Non-Aqueous Phase Liquids (NAPLs) has become an increasing threat. This article studied the steam injection efficiency in groundwater remediation contaminated with non-aqueous phase liquid (diesel) through a bench-scale laboratory experiment. The experimental set up consists of boiler and sandbox. Steam, which was generated from supplied to sandbox at rate 0.14m3/s, pressure 1.5bar temperature 150°C. initial volume diesel used 500ml. At supply sandbox, it observed that mixture heated above their boiling points, change vaporized chamber outlet or recovery side into condenser were separated on cooling using separator. time 0 6 hours showed as increases, recovered increases 66.04% after allowed 6hours. Therefore, evident technique is efficient removal light liquids groundwater.
