Shipping and Storage
Liquid SO2 can be shipped in a number of different ways. Small quantities are available in 68 kg (150 lb) cylinders similar to cylinders for welding gases. The rate of delivery will depend in the temperature of the liquid SO2 in the cylinder. The overall rate of SO2 gas discharge will depend on the heat transfer rate from the surroundings through the walls of the cylinder. At room temperature a discharge rate of about 0.9 kg/h (2.0 lb/h) of gaseous SO2 is possible.
Larger quantities of liquid SO2 are available in one tonne containers.
