Expert Answer:

1. sulphuric acid.
2Sulphur trioxide from the contact tower is passed onto absorption tower where it is absorbed by descending stream of 98% sulphuric acid to form oleum. It is diluted with water to get sulphuric acid of desired concentration.

SO3 + H2SO4 -----> H2S2O7
H2S2O7 + H20 -----> 2H2SO4
