With a view to minimize the dreadful pollution of air I've made a project model to reduce Air pollution. Here I have worked on three main harmful gases.  They are nitrogen oxides, sulfur dioxide and carbon dioxide. There will be three plants which will respectively extract the gases from the air. Another best part of the project is that it will not only extract the gases but also make useful products using them. These plants will be built on SEZ, EPZ where density of the harmful gases is very much high.A plant will be filled with a chamber of silica gel. When the gases from industries will pass through it nitrogen oxides will be extracted by absorption process. Another plant where critical temperature and pressure of carbon dioxide will be maintained. Here carbon dioxide will be extracted. we will use exhaust fans to take the air. Third plant will be used to extract sulfurdioxide. Here -10 degree Celsius temperature will be maintained. So when the mixture of gases from industries and air will pass through it sulfurdioxide will be extracted. Fourth plant will be used to extract nitrogen from nitrogen oxides using lead plates through catalytic change.  We can use the nitrogen and carbon dioxide to make urea fertilizer and sulfur dioxide can be used to produce sulfuric acid which is an essential elements in industries. so here we are not only extracting harmful gases from the air but also amking the best use of it.
