INDUSTRIAL PROCESS IN THE
MANUFACTURE OF SULPHURIC
ACID
Contact Process
DIAGRAM OF CONTACT PROCESS
In the furnace
S(I) + O2(g) SO2(g)
In the converter
STAGE 1
STAGE 2
2SO2(g) + O2(g) 2SO3(g)
In the absorber
SO3(g) + H2SO4(l) H2S2O7(l)
STAGE 3
H2S2O7(l) + H2O(l) 2H2SO4(l)
SO3(g) + H2O(l) H2SO4(l)
Contact process in manufacturing
sulphuric acid
Double absorption plant
Other type of plant
1- Metallurgical
2- spent acid
