JOHOR BAHRU, 31 May 2018 – The closing ceremony of Electrical Engineering Student Symposium (EESS) 2018 was conducted at P19a-BKT6, Faculty of Electrical Engineering, Universiti Teknologi Malaysia, on 27th May 2018. There were several category awards contested in EESS 2018, which involved students from different fields of electrical engineering, including High Voltage. One of the Final Year Project’s students from the Institute of High Voltage and High Current, namely, Norhafezaidi Mat Saman, supervised by Prof. Dr. Zolkafle Buntat won four awards, which consisted of Consolation for Best Paper Award, Best Project Award for High Voltage Track, Excellence Award and Best of the Best Project Award.
The title of final year project was “Performance Study of Non-Thermal Plasma Chamber to Remove NOx from Diesel Engine Vehicle”. One of the main sources of pollutants is the release of nitrogen oxide (NOx) from diesel engine vehicle. Non-thermal plasma (NTP) treatment is a process of removing the NOx release from the incomplete combustion of diesel engines. The concept of high voltage used to generate non-thermal plasma in the project was dielectric barrier discharge (DBD). A non-thermal plasma chamber is an exhaust chamber that has the capability to remove the emission of NOx species. The non-thermal plasma chamber provides oxidation treatment process inside the chamber, known as the non-thermal plasma treatment. The NOx species experiences oxidation process, and then converted to produce nitrogen dioxide (NO2). In the project, a simulation study of the geometric properties of the exhaust chamber was conducted in order to obtain the most effective NTP chamber that could help the process of NOx removal to become more efficient. NTP chamber was then fabricate based on the result obtained from the simulation in order to verify the result based on the actual experiment setup of NTP treatment. The non-thermal plasma generator was develop by using high intensity discharge (HID) ballast with 23 kV AC striking voltage. The effectiveness of NOx removal was determined by taking in count the percentage reduction of NOx.
IVAT congratulates Norhafezaidi on his excellent achievement through his Final Year Project and wishes him the best in his future undertakings.
