    We will first start by addressing the question of what is sulphuric acid. Well, sulphuric acid is basically an oxidizing agent, a strong mineral acid, and a dehydrating agent. Sulphuric acid has the chemical formula H 2 SO 4. The acid is a colorless liquid. It is soluble in water and generally releases heat on contact.

  • Sulfuric acid - Essential Chemical Industry

    sulfuric acid. Sulfur trioxide reacts with water and the reaction can be expressed as: However, water itself cannot be used for absorption as there is a large temperature rise, and a sulfuric acid mist is formed, which is difficult to handle. Instead, sulfuric acid of about 98% concentration is used.

  • Sulfuric acid - Wikipedia

    Sulfuric acid (alternative spelling sulphuric acid), also known as vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with molecular formula H 2 SO 4. It is a colorless, odorless, and syrupy liquid that is soluble in water and is synthesized in reactions that are highly exothermic.

  • Wet sulfuric acid process - Wikipedia

    The combustion gases are cooled to the converter inlet temperature of about 420–440 °C. To process these wet gases in a conventional cold-gas contact process (DCDA) plant would necessitate cooling and drying of the gas to remove all moisture. Therefore, the WSA process is in many cases a more cost-efficient way of producing sulfuric acid.
