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)
