Sulfuric acid

The output of sulphuric acid at base metal smelters today represents about 20% of all acid production. Whereas in 1991 smelter acid production amounted to 27.98 millions tonnes, it is calculated that the output in the following decade will have grown to reach 44.97 millions tonnes in 2001.

Sulfuric acid – the contact process

The use of sulfuric acid is declining in some industries. For example, there is a trend in the steel industry to use hydrochloric acid instead of sulfuric acid in the metallurgic process of pickling, and hydrofluoric acid has replaced sulfuric acid for some applications in the petroleum industry (IARC, 1992; ATSDR, 1998; NTP, 2005).
