Method and plant (1; 1') for the purification of a base composition; the method entails treating the base composition by stripping with an organic fluid and condensing the gaseous part that forms during the stripping; the stripping takes place at a temperature from 150°C to 280°C and at a pressure from 0.1mmHg (0.13mbar) to 10mmHg (13.33mbar);. the condensation takes place at a temperature from 4°C to 150°C and at a pressure from 0.05mmHg (0.067mbar) to 10mmHg (13.33mbar). |
