United Kingdom
| Technique | Description | Applicability | |
|---|---|---|---|
| a. | Optimised liquid phase separation | Separation of organic and aqueous phases with appropriate design and operation (e.g. sufficient residence time, phase boundary detection and control) to prevent any entrainment of undissolved organic material | Generally applicable |
| b. | Steam stripping | See Section 12.2 | Generally applicable |
| c. | Adsorption | See Section 12.2 | Generally applicable |
| d. | Reuse of water | Condensates from the reaction can be used as process water or as boiler feed after steam stripping (see technique b.) and adsorption (see technique c.) | Generally applicable |
