Assume that an industrial emission is composed of following pollutants. The

concentration of each pollutant is higher than its allowable limit given in the related

Regulation. Draw a simple flow chart including the units necessary to decrease the

concentration of these pollutants below to allowable limits$.$ Please try to select the best

technique for each of them and do not include any unnecessary unit. The units should

follow each other with a logical order depends on the emission characteristics. Explain

the purpose of each unit briefly
