Description

Model (scale 1:96) of a contact proces sulphuric acid plant. The view features electrostatic dust precipitators, part of the plant's extensive purification system. The first proces to manufacture sulphuric acid was patented in 1831 by Peregrine Philips Jr. He made it by pasing sulphur dioxide mixed with air over finely divided platinum to produce sulphur trioxide, when is then converted into sulphuric acid. Platinum has now been replaced by vanadium pentoxide. Sulphuric acid has many industrial applications including the pharmaceutical and metallurgical industries.
