Ever-more stringent limits on the emission of sulfur dioxide into the atmosphere have led to
the exploration of techniques to convert it to elemental sulfur, which can be stored safely and
indefinitely in the open. Hydrogen is an effective reducing agent for sulfur dioxide but in addition to
producing sulfur, also produces hydrogen sulfide, which requires separation and a different treatment to
obtain sulfur.
Calculate the product stream composition for the S02
reduction system shown below, using a molecular
species and an atomic species balance. The process is carried out at 1300 К and 1 atm
