Sulfuric acid production
Overview about Sulfuric Acid
Sulfuric acid is one of the most highly produced and important chemicals It finds widespread applications across in various industries and processes such as industrial chemical production (fertilizers, detergents, pigments, dyers), battery manufacturing, metallurgical processes, petroleum refining, dying and textile industry, production of explosives, semiconductor industry, laboratory use, and analytical chemistry, among others.
There are different processes of sulfuric acid production: chamber process, single contact, and double contact process.
The double contact process is currently the most preferred and widely used due to its high conversion ratio of sulfur trioxide to sulfuric acid. High conversion also means less SO2 residues in the emission gas, helping to reduce SO2 emission into the atmosphere and mitigate ambient air pollution.
Sulfuric Acid Production Process
The production of sulfuric acid involves a multi-step process, widely known as the Contact Process or the sulfuric acid manufacturing process. This process converts sulfur dioxide (SO2) into sulfuric acid (H2SO4). The raw materials used for the sulfuric acid production include sulfur containing gases obtained by burning of elemental sulfur, pyrites or off gases from metallurgical industry and also sulfuric acid regeneration.
