Oleum Market: Highlights
Oleum is a cloudy, gray, fuming, oily, corrosive liquid with a sharp, penetrating odor. It
releases sulfur trioxide in the presence of air. This sulfur trioxide reacts quickly with any
air moisture, producing a fine sulfuric acid mist. Inhalation at low concentrations for a
short period causes irritation to the nose, throat, and lungs. Prolonged exposure at higher
concentrations causes burning sensation, coughing, gagging, chest pain, accumulation of
fluid in lungs, and possible suffocation and death.
Oleum is excess sulfur trioxide dissolved in sulfuric acid. Another name for Oleum is
‘fuming sulfuric acid.’ Oleum is usually transported in the U.S. by special rail tank cars
fitted with steam conduits. Industrialists in the U.K. use road tankers to transport oleum.
The oleum form of transport is safer than shipping concentrated sulfuric acid, partly
because oleum is a solid at certain concentrations, while sulfuric acid is a liquid, and partly
because oleum is less bulky. The industrial user then carefully heats the tank car using the
steam conduits to melt the oleum, which is removed as a liquid.
Oleum is used in dyes, explosives, drugs, and other applications.

Key Drivers of Market
Rise in usage of oleum owing to its increase in demand in end-use industries is expected
to drive the market during the forecast period. It is majorly used as an intermediate for
the production of sulfuric acid. As a highly important chemical compound, sulfuric acid is
used in the manufacturing process of a number of well-known chemicals including
hydrochloric acid, nitric acid, phosphoric acid, and many other industrial chemicals.
Demand for oleum is expected to rise due to the growth in demand for sulfuric acid. This,
in turn is expected to propel the oleum market during the forec
