converter enter an absorber where after absorption in acid solution forms a waste gas with a partial 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% SO3,4.23% H,0) b) % of the SO2 entering the converter that is converted to SO3 c) Weight of a 60% dilute H2SO4 needed to produce an 87% H2SO4 d) If the absorbing acid is is 94% H;SO4, what weight of a 14% oleum is formed (587.6) (88.3%) (248.04)
