In this project, the homogeneous advanced oxidation (AOP) process based on the generation of very reactive species such as hydroxyl radicals has been used for degrading Diethanolamine. With the presence of ultraviolet and hydrogen peroxide in this method, degradation of diethanolamine (DEA) in solution will be further studied. Other than that, the effects of initial hydrogen peroxide concentration, diethanolamine concentration, initial pH and temperature will be examined to determine the optimum condition for degrading diethanolamine. In most of petrochemical plant, amine-based CO2 is used to capture carbon dioxide and hydrogen sulphide in the flue gas before it is released to the atmosphere. It is very important to remove carbon dioxide in the flue gas because releasing flue gas with carbon dioxide content to the atmosphere can increase greenhouse gases which then lead to serious environmental problem. An experiment in the laboratory will be conducted and the sample will be analysed by using total organic carbon (TOC) Shimadzu Model equipment to measure the total organic carbon after 4 hours degradation. The experiment conducted involved the effects of initial hydrogen peroxide concentration, initial diethanolamine concentration, initial pH and temperature to the DEA degradation by using UV/H2O2. Finally, optimization of DEA degradation is determined by using Portable StatgraphicsCenturion 15.2.11.0 statistical software and also by doing experiment in laboratory.
