| titleOfInvention | Method for purifying hydrofluorocarbons |
| abstract | The present invention relates to a method for purifying a composition comprising a halohydrocarbon B comprising the steps of : i) providing a composition A1 comprising a halohydrocarbon B and at least one impurity C different from said halohydrocarbon B, ii) compressing said composition A1 and optionally the cooling thereof, so as to obtain said halohydrocarbon B in liquid form in order to form a liquid stream A2 comprising said halohydrocarbon B, iii) distilling said stream A2 obtained in step ii) in order to form and recover a stream A3 comprising said halohydrocarbon B, characterized in that step iii) is carried out in a pressurized distillation device comprising one or more rotating packed bed(s). |
