  • Sulfur Trioxide and Oleum - Veolia North America

    Oleum (Fuming Sulfuric Acid) Oleum is the term used to describe fuming sulfuric acids. Oleum is produced in various strengths and consists of SO 3 dissolved in 100% Sulfuric Acid (H 2 SO 4). Thus, 20% oleum contains 20% SO 3 and 80% H 2 SO 4 by weight. More information on oleum product specifications is given in Table 3. Oleum is

  • Oleum - Wikipedia

    Oleum, or fuming sulfuric acid, is a term referring to solutions of various compositions of sulfur trioxide in sulfuric acid, or sometimes more specifically to disulfuric acid. Oleum is identified by the CAS number 8014-95-7. Oleums can be described by the formula ySO3·H2O where y is the total molar mass of sulfur trioxide content. The value of y can be varied, to include different oleums. They can also be described

    The Oleum and the SO 3 production are strictly connected to the H 2 SO 4 production technology. Liquid SO 3 is produced by evaporation of Oleum and subsequent cooling and condensation. Oleum can be produced by absorbing part of the SO 3 leaving the sulphuric acid converter in a circulation of Oleum at the required strength and maintaining a steady concentration by adding sulphuric acid at 98.5% w.

  • CASE STUDY - CSB

    Oleum, also known as fuming sulfuric acid, is a mix-ture of sulfuric acid (H2SO4) and sulfur trioxide (SO3). Oleum, when released or spilled, gives off sulfur tri-oxide gas. The gas reacts with moisture in air and forms a cloud of sulfuric acid mist composed of easily inhaled droplets, some less than 1 micrometer in diameter. A sulfuric acid cloud is dense, visible, and slow moving.

    The oleum obtained is then dissolved in water to obtain concentrated sulphuric acid. H 2 SO 4 + SO 3 (g) → H 2 S 2 O 7 (l) H 2 S 2 O 7 (l) + H 2 O(l) → 2H 2 SO 4. Uses of Sulphuric Acid In Industries: Up to 50 per cent of this liquid manufactured is used in the production of phosphoric acid which is in turn used to make phosphate fertilizers.
