dc.description.abstractAlkanolamines such as mono- and diethanol-amine are routinely used for the removal of carbon dioxide and hydrogen sulfide from natural gas in a packed or tray tower. Periodic cleaning of the tower is done by high speed water jet and the wastewater generated contains a significantly high concentration of the amine. This wastewater is toxic to bacteria and cannot be treated in a conventional treatment unit by biological oxidation. An alternative technique of treatment is advanced oxidation such as UV-H2O2 or Fenton’s reaction. In the present work, Fenton’s reagent – a combination of ferrous sulfate and hydrogen peroxide – has been used to study the degradation of monoethnolamine in wastewater. Simulated wastewater was prepared by dissolving the amine in distilled water. Degradation studies were carried out in a jacketed glass reactor. Samples were drawn from time to time and the COD was determined to follow the course of degradation. The rate of degradation declines above a pH of 4 because of decomposition of hydrogen peroxide. The concentration of ferrous sulfate, the amount of hydrogen peroxide and the pH are the important parameters that determine the rate of reaction. The effects of all these parameters have been studied. The reaction proceeds very fast at the beginning but the rate of degradation slows down at larger time. The samples drawn at different times have been run on the HPLC to find out the degradation products. Over sixty percent degradation could be achieved by using nearly stoichiomentric quantity of hydrogen peroxide. A simple pathway of the oxidation process through is proposeden_US
