Abstract: The ethyl glycol monobutyl ether (butyl oxitol, BO), a volatile organic compound, is a toxic and water soluble substance. The removal of this pollutant by using a wet scrubber is an interesting technique due to its low operation cost and pressure drop. The aims of this study were to investigate the absorption efficiency of the wet scrubber and to determine the optimum operating conditions, which cause minimum effect to production line. The effect of solution flow rate and dissolved BO concentration on absorption efficiency was conducted in a pilot plant wet scrubber at the site. It was found that the absorption efficiency of all water flow rates achieved 100% at the beginning of operation. Then they gradually decreased and reached the minimum at 60%, 60% and 30% for water flow rate of 24.7, 19.7, and 14.6 m3/h, respectively. A wet scrubber system with water recycle at laboratory scale was conducted to study the effect of BO vapor flow rate at various water temperatures and loading ratios on the solubility of BO. It was indicated that the absorption capacity of BO increased with increasing of water temperature. Moreover, the absorption efficiency significantly declined when dissolved BO concentration reached 12,000 ppm. BO absorption rate in gas and liquid phase were. 1.89x10 kg/m (column volume) .s and 1.93x10 kg/m (water volume).s respectively. The simulation showed that the wet scrubber was subject to loading ratio of 2.5 1/m. The water should be changed on the third day of operation.
