Production of Elemental Sulphur from SO2
WorleyParsons has over 50 years of global experience
that includes 534 sulphur recovery units, accounting for
over 60% of the world’s production of recovered sulphur
and including the world’s largest single-train sulphur
plant.
Sulphur emissions for ore roasters, smelters, and coal-fired power plants need
to be reduced considering:
•
•
•
•
•
•
f Combination of two well proven processes

Claus-type plants
Less demand for sulphuric acid production
Lower fuel consumption
Reduced emissions
Better product sulphur quality
Better operational stability
