SO2 Emission Control and Finding a Way Out to Produce Sulphuric Acid from Industrial SO2 Emission

Papiya Roy and Arghya Sardar

Sulphur dioxide (SO2) is one of a group of highly reactive gases known as “oxides of sulphur”. SO2 is linked with a number of adverse effects on the respiratory system and other environmental issues. It is an important industrial emission gas which causes several difficulties in the environment like acid rain. Sulphur dioxide is a ubiquitous component of fuel combustion exhausts and one of the first air pollutants to be regulated all over world. Several approaches have been adopted to reduce SO2 content in the environment. One of the most difficult environmental problems facing industry is how to economically control SO2 emissions. Conversion of H2SO4 from SO2, which could be a great impact on reducing pollution. Production of sulphuric acid is one of the best choice considering its economical values and utilities. This paper addresses the different processes to control SO2 and to use SO2 in most economic and productive way to reduce SO2 effect in environment. A review of various treatment methods has been provided and a brief description of each process has been included and their technical applicability is also compared.
