· Sulfuric acid plant - production process Concentrated non-condensable gases (CNCG) are collected and lead to a collection tank, from which they are taken to a separate incinerator. In the separate incinerator, total reduced sulfur compounds in the CNCG are oxidized into SO2. The flue gas from the boiler is led to a catalytic reaction vessel.

A new metallurgical sulfuric acid plant (3760 tonnes of acid per day) is costing ˜59 million U.S. dollars (Sulfuric 2005). Production of pure sulfuric acid from contaminated 'spent' sulfuric acid catalyst is almost always done near the source of the spent acid – to minimize forward and return acid shipping distance.

The Sulfuric Acid Dilution System can produce the diluted sulfuric acid continuously to an entitled level of concentration via diluting the concentrated sulfuric acid with the help of a dispersion mixer. It is considered safe to work with because it is designed inline. Heat exchanger removes the excess heat produced during the dilution process ...
