The liquid sulphur dioxide market in India comprises the production and supply of liquid sulphur dioxide (SO2), a chemical primarily produced by burning sulfur or through the treatment of sulphite compounds with acid, followed by cooling and liquefaction. Liquid sulphur dioxide is widely used across industries such as chemicals, food processing, wastewater treatment (for neutralizing chlorine-based waste), and oil refineries due to its versatile chemical properties. However, it is also highly toxic and corrosive, requiring strict handling and storage measures.
