Raschig rings

Among various packing materials in the market, carbon / graphite Raschig rings are distinguished by following characteristics :

• They are unaffected by most violent thermal shocks.

• They resist perfectly to almost all corrosive fluids used in industry, in particular to those which attack aluminium, silicate materials (hydrofluoric acid, boiling hydrochloric acid and hot caustics).

• They are perfectly wetted by all liquids (aqueous solutions, molten salts, etc) and ensure, therefore, maximum efficiency at envisaged operation.

• These highly remarkable qualities which characterize carbon / graphite Raschig  rings make them valuable auxiliaries in industries which require following treatments for their production :

                                       WASHING                              DRYING
                                       DISTILLATION                      RECTIFICATION

• Prices of carbon / graphite Raschig rings are nearly half of S. S. tower packings.

• Carbon Raschig rings have one third the weight of metal tower packings.

• They have a crushing strength of 600 kg/cm2 and negligible porosity.

• Normal recommended service usage :

1. Caustic scrubbers – Merox units , in Isomerisation units for MSP ( EURO -III) for Refineries.
2. Ethyl alcohol ( Sulphuric alkylation) stripping towers.
3. HCL stripping towers – HCl tailend absorbers
4. 70% sulphuric acid + 15% HF pre-scrubbing towers.
5. Carbon dioxide absorption towers with M. E. A.
6. High temp. weak sulphuric + HCl wash towers.
7. Penex Units
8. Weak Acid Cooling Towers
