Project description

As part of the complete Uranium Project currently being performed by Aveng E+PC for Paladin Resources in Malawi, a requirement for Sulphuric Acid Plant for the Leaching of the uranium ore arose. An enquiry went out to the market place for the supply of a 230 ton per day Acid Plant. Aveng E+PC proposed an EP contract for the supply of an Acid Plant to be erected by the main contractor on site.

The plant will be a double absorption plant with a sulphur burner as feed for the SO2 gas. A four pass Converter and Superheated Steam system will form part of the major equipment on site. This will be the first Acid Plant supplied by Aveng E+PC under the new Outotec License agreement for Sulphuric Acid Technology.
