Abstract

Air pollution is mostly caused by toxic gas pollutants, which include Nitrogen Oxide (NOx), produced from incomplete combustion processes. However, to overcome this, a number of technologies for its removal has continuously been developed, one of which is chemical absorption, using membrane modules. This research, therefore, aims to investigate the optimum absorption condition of polysulfone-based hollow fiber module membrane, used as a bubble reactor, with strong oxidizing agent mixture, composed of hydrogen peroxide (H2O2) and nitric acid (HNO3) as it's absorbent. Furthermore, the independent variable observed is the concentration of H2O2, which was set to 0,25; 0,5; 1; 5; 10 wt.%, while the concentration of HNO3 was kept constant at 0.5M, and the inlet flow rate of the NOx gas was set constant at 150 cc/minute. However, the experimental results showed that the amount of NOx absorbed and its efficiency improves with elevating the H2O2 concentration. Conversely, the experiment also showed that membrane modules with a higher number of fibers, results in enhanced absorption efficiency. The maximum NOx removal efficiency achieved in the study was 94.6% using 10% H2O2 and membrane module with 48 fibers.
