Case Study: BTEX removal from produced water

asked May 8, 2015 in Process by ChemKB (8,210 points)
A Gas Plants XYZ had experienced increased ambient air Benzene, Toluene, Ethyl benzene and Xylenes (BTEX) concentrations around its various evaporative ponds, which was used for process wastewater disposal. The BTEX concentration was within allowed concentrations and also not causing any operator hazards. However there was a study conducted to remove the residual BTEX completely from the produced water. The BTEX source was primarily from the TEG regenerator vent gas stream. See answer for the source of the problem, study finding and the solutions.
