Treatment and Recovery for Flue Gases: a Review

Abstract

In the industries such as petroleum, sugar, chemical, fertilizers, dyes, textiles, etc., the composition of flue gases contains sulphur dioxide, carbon dioxide, oxides of nitrogen and particulate matter. Stringent flue gas emission standards call for effective treatment method for flue gases. The presence of these flue gases in environment can affect ecological cycle. Many physical separation methods can be used for particulate matter. The gaseous emissions can be dealt with by using various absorption, adsorption and catalytic treatment methods. The present review summarizes studies and research for treatment of flue gases in industries.
