Desulfurization and Emissions Control.

Desulfurization removes elemental sulfur and its compounds from solids, liquids, and gases. Predominantly, desulfurization involves the removal of sulfur oxides from flue gases, compounds of sulfur in petroleum refining, and pyritic sulfur in coal cleaning. This chapter discusses the following topics: 1.Sulfur pollution (sulfur oxides, hydrogen sulfide, and organic sulfur pollutants).2.The US Air Quality Act.3.Solid-phase desulfurization (coal cleaning, gasification, and liquefaction).4.Liquid-phase desulfurization (acid-lake restoration for H2SO4 removal and groundwater decontamination for H2S removal).5.Gas-phase desulfurization (SOx and H2S removals from air emission streams).
