General Description
A colorless gas with a choking or suffocating odor. Boiling point -10°C. Heavier than air. Very toxic by inhalation and may irritate the eyes and mucous membranes. Under prolonged exposure to fire or heat the containers may rupture violently and rocket.

Liquid sulphur dioxide (SO2) is a versatile chemical with many uses, both in liquid form or as a source of gaseous SO2. Liquid SO2 is used the pulp and paper industry, mining industry, and in the food industry as a preservative. It can function as a reducing agent, an oxidizing agent, a pH controller, purifying agent, preservative, a germicide and bleaching agent. SO2 can also be used as a refrigerant, heat transfer fluid and selective solvent.

Process:

Sulphur dioxide may be produced by a variety of routes, such as the combustion of Sulphur or pyrites, alternatively as a by-product of smelter operations.

It can also be prepared by the reaction of an acid on a metallic supplied, or by the action of sulphuric acid directly on a metal such as copper.

Application: 

Sulphur dioxide is used

1. in the manufacture of sulphite, hydrogen sulphites and sulphuric acid
2. to sterilize wine and beer making equipment in order to imhibit the growth of moulds and bacteria, and to control wine fermentation
3. in a variety of disinfecting and fumigation applications
4. as a component in environmental calibration gases
5. in the float glass manufacturing process

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.

FAQ

1.What's your product price?

Because each gas price depends on the market supply and demand, quantity and purity, it is difficult to give a fixed price. 
If you have any interested in each gas, pls give your details requirement. I could like to make an offer to you.

If the cylinder is in stock, and only need to fill gas, the delivery is about 7-10 days ex work after receive the deposit.

If the cylinder need to customize, the delivery is about 15-35 days ex work after receive the deposit. That depends on the quantity.

4.How to check the gas quality?

Firstly, our cylinder will take a treatment (cleaning, drying, vacuum pumping, and replacement before filling gas. In this way, the cylinder inside is clear and dry. Secondly, we will take tests every treated cylinder to assure them inside purity. Thirdly, we will take a test for all of the gas after fill into cylinders. If the tested gas is not up to standard, we will produce it again and not release the faulty product to ex work. At last, we will supply you the gas testing qualified report .

5.All the cylinders can be recycled?

Usually seamless steel cylinder can be recycled to use in 20 years. 
The disposable cylinder is only use for one time.

6.Shall we send back the cylinders to China to refill gas again?

Yes, when you ordered our cylinders, next time, you can send back the cylinders to fill gas again. You just need to tell us before you export. We will handle all the import customs clearance formalities.
