AI Overview
In a sulphonation plant, the
to
conversion tower (or converter) is a critical component where sulfur dioxide (
) is oxidized into sulfur trioxide (
) in the presence of a vanadium pentoxide (
) catalyst. This conversion is a crucial step in producing
for sulfonation/sulfation of detergent raw materials.

What are the conditions for converting SO2 to SO3?
Favourable conditions for the conversion of SO2 to SO3 are as follows: Exothermic reactions are favoured at low temperature, and the yield is maximum at about 410–450°C. Pressure of about 1–2 atmosphere is used. Excess of oxygen increases the production of sulphur dioxide.Jul 31, 2021

What is the pressure kept during the conversion of SO2 to SO3?
The typical pressure for this reaction is 1-2 atm, which is already enough to convert nearly 100% of the sulfur dioxide into sulfur trioxide. The addition of a V2 O5 catalyst also boosts the forward reaction's speed without altering the conversion rate.

How do you convert sulfur to SO3?
Liquid sulfur goes to the sulfur burner by precise measurement and fully combusts with dry air to generate SO₂; after cooling, SO₂ gas goes to the converter and convert to SO₃ by vanadium catalyst.
