Answer c) and d)

converter enter an absorber where after absorption in acid solution forms a waste gas with
a nartial orsat analysis of 0.55% SO2. Calculate per 100 kg raw sulfur:
a) Complete analysis of the burner gas
(9.59% SO2 , 9.03% O2, 76.08% N2 , 1.07% SO3 ,
b) % of the SO2 entering the converter that is converted to SO3
c) Weight of a 60% dilute H,SO4 needed to produce an 87% H,SO4
d) If the absorbing acid is is 94% H,SO4, what weight of a 14% oleum is formed (587.6)
4.23% H,0)

5. Raw Sulfur containing 83% pure S is burned together with 80% excess air (S to So, ) An
analysis of the cinder shows 20% unburned sulfur and 80% inerts. 90% of the sulfur gasified
burns to So, and the rest to SO3 . Air is supplied saturated at 30 °C and 750 mm Hg. The
gases from the burner enter a converter where catalytic oxidation of SO2 to SO, tales
