Scheme for Rubber Industry Waste Gas Treatment

I. Industrial Rubber Waste Gas

 A lot of organic waste gases will be produced in rubber industry. The characteristics of the waste gases are large emissions and complex and changeable pollution components. Rubber exhaust contains odorous substances, which can stay in the air for a long time, and will cause various adverse effects. And the rubber material production industry is the first batch of pilot air volatile organic compounds (VOC) emission fee industry in China, which shows its importance.

II. Main Components of Industrial Rubber Waste Gas

 Rubber is widely used in tires, seals and other industries. Smoke produced during the production of mixing and sulfurizing plants contains trace organic components such as H2S, NH3, CS2, mercaptan, organic sulfides and amines.

Sources of VOCs

Organic waste gases produced in the process of rubber refining;

Organic waste gases in the process of dipping and drying of fibre fabrics;

Organic waste gas produced during calendering process;

Organic waste gas produced in vulcanization process;

Organic waste gases produced by resins, solvents and other volatile organic compounds when they are proportioned and stored.

There are three main sources of rubber exhaust gas:

1) Release of residual organic monomers. Raw rubber, such as natural, butyl benzene, cis-butyl, butyl, ethylene propylene, chloroprene rubber, etc., has great toxicity. Under the conditions of high temperature thermal oxidation, high temperature plasticization and combustion, these raw rubber dissociates trace monomers and harmful decomposition products, mainly alkanes and olefin derivatives.

2) Volatilization of organic solvents. Gasoline is widely used as organic diluent in rubber industry.

3) Thermal reaction products. When rubber products are produced at high temperature, it is easy to cause thermal reactions between various chemicals and form new compounds.
