Sulfur used to produce sulfuric acid: raw material is sulfur, and the final product is sulfuric acid. Please write down the chemical reaction equation for this production process
Sulfur is melted in a sulfur melting tank and then fed into a sulfur combustion furnace where it burns to produce SO2. The SO2 is sent to a catalyst furnace where it reacts chemically with O2 to form SO3. The SO3 gas then reacts chemically with H2O in an absorption tower to produce sulfuric acid. Sulfur --> Melting tank --> Sulfur burning furnace --> S02 gas --> Catalyst furnace --> S03 gas --> Absorption tower --> H2S04. S02 + O2 = S03; S03 + H2O = H2S04
1. S+O2----SO2 2. 2SO2+O2===2SO3 3. SO3+H2O-----H2SO4
Oxidation of sulfur + catalytic oxidation of SO2
S+O2 (combustion) = SO2 2SO2+O2 (catalysis) = 2SO3 2SO3+2H2O (absorption) = H2SO4
S+O2=SO2 2SO2+2O2=2SO3 SO3+H2O=H2SO4
S+O2=SO2 2SO2+O2 =catalyst SO3 SO3+H2O=H2SO4
Reply to 1# I love chemical engineering: 1. S + O2 == SO2 + 9282 kJ/kg of V2O5; 2. SO2 + 1/2 O2 == SO3 + Q; 3. SO3 + H2O == H2SO4 + Q
S+O2==SO3 (in the presence of a catalyst) SO3+H2O==H2SO4
S+O2=SO2 2SO2+O2 = SO3 SO3+H2O=H2SO4
S+O2------->SO2+Q Combustion High temperature 2SO2+O2→2SO3+Q With vanadium catalyst at high temperature SO3+H2O---->H2SO4+Q
