Abstract

The H2S is burnt in air in a non-catalytic combustion chamber, the reaction prods. being then fed via a recuperator-boiler to S condensers in cascade, >=1 catalytic reactor being between 2 successive condensers, the reaction-gases being reheated before entry to each reactor, and when the feed-flow is below nominal at least part of the residual gas is recycled upstream of >=1 catalytic reactor. This gives flexibility of operation with different feed flow rates. S fogs and solids are obviated.
