Applications
- Oilfield produced water oil removal for reinjection
- BTEX (benzene, toluene, ethylbenzene, xylene) removal
- COD reduction for produced water surface discharge
- Offshore platform produced water treatment
- Tight oil and shale gas produced water recycling pre-treatment
Key Features
- High BTEX adsorption capacity — benzene adsorption ≥450 mg/g for aromatic hydrocarbon removal
- Effective oil removal from produced water to < 1 mg/L residual
- Chemically resistant to oilfield brine at pH 4–9
- Suitable for fixed-bed or moving-bed configurations in onshore and offshore systems
