APPLICATION OF RESPONSE SURFACE METHOD IN THE DEGRADATION OF WASTEWATER CONTAINING MDEA USING UV/H2O2 ADVANCED OXIDATION PROCESS
HARIMURTI, SABTANTI; UR RAHMAH, ANISA; OMAR, ABDUL A.; MURUGESAN, THANAPALAN (SCIENCE ALERT, 2012-06-30)Methyldiethanolamine (MDEA) solution is frequently used for the removal of acidic gases from raw natural gas. During maintaining, cleaning and scheduled inspection of absorption and desorption column of sweetening gas ... -
DEGRADATION KINETIC OF OXYTETRACYCLINE ANTIBIOTIC INSIDE UV REACTOR IN THE PRESENCE OF H2O2
UR RAHMAH, ANISA; HARIMURTI, SABTANTI; OMAR, ABDUL AZIZ; THANAPALAN, MURUGESAN (Trans Tech Publication, 2014-09)Oxytetracycline (OTC), a widely used of veterinary antibiotic, was degraded inside a UV/H2O2 system. Kinetic study was conducted at 30°C of temperature and pH 6.37, as suggested by the previous optimization experiment. ... -
THE DEGRADATION MECHANISM OF WASTEWATER CONTAINING MDEA USING UV/H2O2 ADVANCED OXIDATION PROCESS
HARIMURTI, SABTANTI; OMAR, ABDUL AZIZ; UR RAHMAH, ANISA; THANAPALAN, MURUGESAN (IEEE, 2011-09-19)Alkanolamines such as MEA, DEA, MDEA and DIPA in aqueous solutions is frequently used for scrubbing carbon dioxide from natural gas. High quantity of alkanolamine appears in the wastewater during cleaning and maintenance ... -
EFFECT OF BICARBONATE ON THE MINERALIZATION OF METHYLDIETHANOLAMINE BY USING UV/H2O2
HARIMURTI, SABTANTI; UR RAHMAH, ANISA; OMAR, ABDUL A.; MURUGESAN, THANAPALAN (SCIENCE ALERT, 2014-03-24)The presence of bicarbonate affects the degradation efficiency of effluents containing aqueous methyldiethanolamine (MDEA) solution leaving the CO2 absorption/regeneration unit of natural gas processing units. In the present ... -
