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