Contact Process
The Contact Process is the main way to make sulfuric acid on a large scale. It uses chemical reactions to turn sulfur dioxide (SO2) into sulfur trioxide (SO3). Then, SO3 is mixed with water to create concentrated sulfuric acid (H2SO4).
- Oxidation of sulfur dioxide (SO2) to sulfur trioxide (SO3) using a catalyst, typically vanadium pentoxide (V2O5).
- Absorption of the produced sulfur trioxide (SO3) in water, forming sulfuric acid (H2SO4).
- Concentration of the sulfuric acid solution to the desired strength, typically 98% or higher.
Chamber Process
The Chamber Process is an older way to make sulfuric acid. It directly mixes sulfur dioxide (SO2) with oxygen (O2) and water vapor. This creates sulfuric acid (H2SO4) in lead-lined chambers.
- Combustion of sulfur to produce sulfur dioxide (SO2).
- Oxidation of sulfur dioxide (SO2) to sulfur trioxide (SO3) using air and water vapor.
- Absorption of the sulfur trioxide (SO3) in water, forming sulfuric acid (H2SO4).
- Concentration of the resulting sulfuric acid solution.
