What is Sulfur Dioxide?

• Sulfur dioxide is a combination of oxygen and sulfur.
• In normal conditions, at normal temperatures and pressures, sulfur dioxide is a colorless gas with a very nasty odor that can cool and compress and turn into a colorless liquid.
• This gas at a pressure of 1 atmosphere and Its boils at the temperature of  10 C
• This gas at temperature  -9.75 C Freezes.
• Liquid sulfur dioxide is heavier than water and in the gas phase, it weighs twice as much as air.
• It is also non-flammable in any of the liquid and gaseous phases and is stable in a chemical bond.
• This gas becomes very corrosive to metals in the presence of a very small amount of water, sulfur dioxide, except in the presence of lead, stainless steel 316, and special alloys.
• The Special glass and plastics are resistant to impure (hydrated) sulfur dioxide.

Available grades:

% 9.99 in the liquid phase

Tanks and maintenance:

• Sulfur dioxide can be charged in pressurized cylinders.
• This gas can also be charged and transported in tons of tanks, portable flasks, and cargo tanks.
