Title:
METHOD FOR THE TWO-STAGE CATALYTIC OXIDATION OF SULPHUR COMPOUNDS IN WET GASES
Document Type and Number:
WIPO Patent Application WO/2014/056013
Kind Code:
A3
Abstract:
The method relates to a two-stage catalytic oxidation of sulphur compounds in wet gases, in which 98 % by weight sulphuric acid is recovered in a counter-current in a condensation tower (K) comprising sulphuric acid, the heat is transferred to the crude gas via a heat exchanger system (W1, W2, W3, W4) and the gases are desulphurized by more than 99.8 % after the first reactor stage, (R1), quenching (Q), filtration (F) and the secondary reactor stage (R2).
