N2  - In glass bottle manufacturing plants, products are formed by melting raw materials at approximately 1500 °C using heavy oil and liquefied natural gas (LNG) in a melting furnace. The exhaust gas generated during this process contains nitrogen oxides (NOx), sulfur oxides (SOx), and particulate matter (PM), which contribute to environmental contamination when released into the atmosphere. Conventional exhaust treatment systems for glass melting furnaces typically include wet or semi-dry desulfurization equipment utilizing sodium hydroxide (NaOH), a compound that readily reacts with sulfur dioxide (SO2), and dust collectors such as electrostatic precipitators or bag filters that primarily collect sodium sulfite (Na2SO3) and sodium sulfate (Na2SO4) produced during the desulfurization process, effectively enabling desulfurization and PM removal. However, they lack an efficient method for NOx removal due to the presence of catalyst poisons, including sticky dust, in the exhaust gas. This study proposes a plasma-chemical hybrid process (PCHP) for the simultaneous removal of NOx and SOx. This process integrates plasma oxidation with chemical reduction and can be incorporated into existing desulfurization reactors. Furthermore, this study applies PCHP to an operational glass melting furnace exhaust gas treatment system, achieving simultaneous removal of PM, NOx, and SO2.
