Malaysia has one of the most extensive natural gas pipeline networks in Asia. Using pipeline system, the gas will be channelled to the onshore station where the natural gas will undergo separation of acidic gases. Nowadays, the removal of toxic gases such as H2S and CO2 via chemical conversion attracted many researchers due to the effectiveness of the technique. In this research, new catalysts of high industrial impact that can catalyze the reactions of CO2 methanation and H2S desulfurization were developed. A series of catalysts based on nickel oxide doped with ruthenium, rhodium, palladium...

N-methyldiethanolamine (N-MDEA) is used in the natural gas refinery process to remove carbon dioxide (CO2) and hydrogen sulphide (H2S) and was discharged as pollutants with other aromatic hydrocarbons such as Benzene-Toluene-Xylene (BTX) compounds. The small leakage of this component will contaminate the environment and lead to heavy water pollution. These dangerous materials that polluted the water system can effect the aquatic life by consume dissolved oxygen. Thus, some effort must be carried out to overcome these problems. In this study, photocatalytic process has been introduced for the...
