Cleanol
Cleanol™ is the result of Axens Solutions experience and know-how with those two technologies: Glycol units & Sulphur production units (Claus). Cleanol™ is an efficient process which allows environment preserving, reduced energy consumption, high glycol regeneration performances.
Operating Principle
A combustion chamber integrated with a Glycol Reboiler
- Effluents combustion from regenaration column
- Use of steams from combustion chamber to provide the heat required by the glycol reboiler
- Use of the balloon flash gas as stripping gas
- The hydrocarbons needed to produce the heat required by the reboiler are used first for glycol stripping
Process Scheme
Performances & Key Benefits
- Reboiler operating at 198°C instead of 204°C
- Skin temperature of lower tubes is below 210°C
- Regeneration column head system & torch are removed
- The Lower Calorific Power of effluents to burn is more stable
- Homogeneous temperature in the combustion chamber (no chimney effect)
- Combustion efficiency
- Complete assembly of the package in a workshop
- No liquid effluent
- « Clean » gaseous effluent (CO2 and H2O only)
- Fuel gas saving
- Operation flexibility
- Reduced glycol degradation risk
- No flue between combustion chamber and reboiler
