Applications of SO2 Gas in Production and Industries Today
SO2 gas has outstanding advantages and is most commonly used in the industrial production of sulfuric acid and as a bleaching agent. So, what is SO2 gas? What is sulfurous gas, and what are its characteristic properties? Let’s explore everything about SO2 in this article by Migco.
Applications in Chemical Preparation and as a Cleaning Agent
♦ SO2 gas, or Sulfur dioxide, is an important intermediate used in the production of sulfuric acid.
♦ Sulfur dioxide gas is also a very effective deodorizer.
♦ SO2 is also a quick paper bleaching agent and is used to treat delicate materials such as clothing.
Food Preservation:
♦ Sulfur dioxide gas is used to preserve dried fruits such as dried apricots, dried fruit, and other dried fruits. It is used because of its antibacterial properties, known as E220.
♦ It acts as a preservative to maintain the fresh color of the fruit and prevent rot and decay.
♦ It is also used as a safe preservative and bleaching agent for molasses.
Food and Beverage Production:
♦ SO2 gas is used in the production of some wines. Sulfur Dioxide gas remains an important compound, measured in parts per million, for wine production.
♦ It acts internally as an effective antibacterial and antioxidant, protecting wine from spoilage caused by bacteria and oxidation. The antibacterial activity of this gas also helps minimize volatile acids.
Environmental Treatment:
♦ In the treatment of municipal wastewater, sulfur dioxide gas is used to treat wastewater containing chlorine.
A Fast Refrigerant:
♦ SO2 gas can be easily condensed and has a high evaporation temperature, so it is used as a material for refrigerants.
♦ Before the development of chlorofluorocarbons, sulfur dioxide gas was commonly used as a refrigerant in household refrigerators.
