Production - Sulfuric Acid

Sulfuric Acid can be made in two different processes. One is called Lead Chamber and the other is called Contact.The Lead Chamber Process is the older process, and is used to produce the acid used in fertilizer, which is a more dilute acid.Contact is used to make purer Sulfuric Acid, but is more expensive, as it requires purer raw materials and more expensive catalysts.

Sulfuric acid: Pumping up the volume

But in 1875, a contact-process acid plant was started up at Freiberg in Germany, using lead-chamber sulfuric acid decomposed by heat as a source for pure sulfur dioxide. From the mid-1880s on, the output of acid produced by the contact process grew rapidly. By then, gases from pyrites had replaced sulfuric acid as a source of sulfur dioxide.
