Sulfuric Acid - H2SO4


Sulfuric acid is the largest volume commodity chemical in the world.  It is produced worldwide, with the largest application into the phosphate fertilizer industry.  AkzoNobel has been producing sulfuric acid for 50+ years in Le Moyne, Alabama, USA and San Lorenzo, Argentina. Unlike many producers, AkzoNobel manufactures sulfuric acid directly from molten elemental sulfur yielding a pure product with almost no contaminants. The product is sold in 93, 96, and 98% strengths.

Major applications

While the largest application for sulfuric acid worldwide is fertilizers, AkzoNobel markets much of its product into the pulp and paper industry, often for use in chlorine dioxide generation (the high quality of our product is important in this application). AkzoNobel sulfuric acid is also used in many other chemical processes and in various wastewater and pH control applications.

Handling/Responsible Care

We ship this product in bulk tank trucks and in railcars. These containers are dedicated to sulfuric acid service to insure the highest quality. Sulfuric acid is a highly corrosive product and must be handled with care. We offer customized technical service to our customers to help insure the product is stored and handled in a safe and environmentally friendly manner. 

Oleum, also called Fuming Sulfuric Acid, is sulfur trioxide dissolved in sulfuric acid. AkzoNobel Argentina obtains it at a 22% concentration of free SO3, from the saturation of 98% sulfuric acid. The high quality of the raw materials used in the process leads to a chemically pure product, free of heavy metals and with low iron content.

Oleum is mainly used in sulfonating processes, such as detergent manufacture.

Liquid at 22% concentration of free SO3 (equivalent to 105% concentration: H2SO4), iron content lower than 100 ppm; delivered in 30 tons tankers.
