Environmental Concerns and the Importance of Desulfurization

Abstract

The increased utilization of fossil fuels and subsequent industrialization in most of the world has led to a remarkable increase in the atmospheric sulfur compounds concentrations. Pollution released by the use of petroleum-based fuels contributes immensely to the deterioration of air quality despite regulatory and technological advances in place. SOx, NOx, and particulate matter are constantly emitted to the environment which affects public health, ecosystem, and general wellbeing of the people living mostly in urban areas. Sulfur dioxide, which is the immediate sulfur compound found in the lower atmosphere after combustion of fuels, has a major role to play in the formation of acid rain, smog formation, and particulate aerosols. Each of these formations affects the healthy living of animals, plants, soils, water, and the general ecosystem. This chapter discusses the environmental issues of sulfur.
