Abstract
An integrated method for the derivation of useful energy from steam containing both hydrogen sulfide and an alkaline acting component, such as ammonia, while substantially reducing the emission of sulfur-containing compounds to the atmosphere. Pretreatment of the steam to selectively remove the alkaline acting components results in the concentration of hydrogen sulfide in the uncondensed vapor as the steam is condensed during energy derivation. The uncondensed vapor is separated from the steam condensate and then is treated to produce an environmentally acceptable vent gas.
