Graphite /Carbon Raschig Rings have assumed an important functional role in the working of absorption towers, distribution columns, scrubbers, etc, in chemical plants and refineries. With the growth of chemical industries, the need for versatile Raschig Rings has also grown proportionately.

Graphite /Carbon Raschig Rings are characterised by unique properties as follows

---

• Because of their high thermal conductivity they are resistant to severe thermal shocks.
• Low thermal expansion.
• They are resistant to practically all corrosive chemicals over a wide range of temperatures - these include almost all acids, alkalis, alcohols, organic solvents, inorganic compounds and salts.
• If required these can also withstand higher process temperatures. Impervious carbon rings are superior in oxidising conditions.
• Because of their excellent wettability by all liquids (water, inorganic salt solutions, organic solvents), they exhibit maximum efficiency during operation. This type of tower packing is selected mainly based on the chemical conditions involved as well as for reasons of mechanical strength, resistance to corrosion and a balance of cost, capacity and efficiency.

Since it exhibit such remarkable versatility that these find increasing usage in chemicals plants.There are few applications where the low cost of carbon rings does not play an important part in its selection.
