Integrated thermal treatment of acid sulfate soils

摘要

The present invention provides a method of thermal treatment of acid sulfate soil (ASS), a method to inhibit corrosion in a combustion plant by using the sulfurous gaseous released in the thermal treatment. The invention further provides an integrated system comprising a thermal treatment plant and a combustion plant wherein the heating in the thermal treatment is effected by heat from the combustion plant, and the sulfurous gases released in the thermal treatment is used as corrosion inhibitor in the combustion plant, and related aspects.
