Use of Chemical Scrubbing Method to Minimise the Pollutants

In present study, a low-cost device has been developed to reduce the pollutant coming out of petrol engine. The exhaust gases such as carbon dioxide, sulphur oxides and nitrogen oxide have been reduced. The pollutant gases coming out of petrol engine are allowed to pass through an absorbent material. The absorbent material absorbs some amount of exhaust gases. The remaining amount of gases reacts with the chemical sprayed on the absorbent material. The different kind of aqueous salts has been formed as the exhaust gases react with the NaOH. The quantitative analysis of aqueous salts has been performed to determine the quantity of pollutant before and after using the device. The results show that the amount of pollutants in exhaust gas has been reduced after attaching the device to the exhaust pipe.
