Hello everyone,
Can someone give some advice on which process to chose to convert H2S to SO2.
My H2S gas stream has about 90% H2S and about 7% CO2 by volume. There are several other hydrocarbons (upto C3) in the stream as well, some amount of COS is also present.
I read about the Claus process but I believe that it focusses on converting to elemental sulphur. My main motive is to get SO2 so I can use SO2 to produce H2SO4.
Is direct burning of H2S to SO2 possible at such high volume % of H2S in the gas stream. How much conversion is possible?? Can we avoid formation of elemental sulphur?
Are there any other options?? (total molar flow rate of the stream is somewhere between 700-750 kgmole/hr.)
