Air Pollutant Reduction from Diesel Engine Employing Wet Scrubber System 2022-28-0586

The problem of air pollution particularly particulate matter has to be considered seriously for the workers in confined spaces such as mines etc. This serious impact can be solved with the inclusion of wet scrubber in the exhaust system which removes the toxic particulate matter from the exhaust gas stream. In the wet scrubber, the exhaust gases from diesel engines are being brought into contact with the scrubbing liquid. In the current study, wet scrubber was designed and fabricated employing various nozzles at different orientations so that it facilitates effective encounter of gaseous pollutants with the scrubbing liquid. The experimental study was carried out employing both human and equipment assessment. The study was conducted with the inclusion of biodiesel blend (B20) together with the scrubbing system and the results were compared with the baseline diesel fuel. Also, the experiment was repeated using variation of parameter of scrubbing liquid like temperature i.e., cold and hot liquid. Along with the emission parameters, exhaust odor reduction and eye irritation time were noted. Thus, it was observed that effective reduction of pollutants, eye irritation and odor intensity was achieved with the addition of biodiesel as well as exhaust gas treatment system i.e. wet scrubber system. The optimum conditions for CO, HC Smoke level, Odor rating and Eye irritation time was observed at the load of 25%.
