Oily Sludge Treatment Solution
Oily Sludge Definition
It refers to the oil produced by mixing the oil and the produced water in the oil & gas fields, refining process with the ground soil, oil tanks bottom sludge and the oily sludge water mixed product produced by ETPs and STPs.
Classification of Oily Sludge
Process
* Treatment process for high liquid content (fluid) oily materials
1. Pretreatment:
- Fluidized liquefaction
- Debris separation
2. Heating materials:
Quenching and deemulsifying Coagulation/flocculation
3. Solid-liquid separation and dehydration:
(Three-phase separation)
4. Oil recycling;
Water treatment;
Solid bacterial composting
5. Thermal analysis processing Indirect heat treatment
Recycle valuable items
6. Disposal of residues Cool down and reduce dust
Residue detection
* Treatment process for high solid oil (solid) materials
1. Debris cleanup
Excavation transportation
2. Pretreatment:
Material crushing screening
3. Thermal analysis processing Indirect heat treatment

Sludge Drying and Carbonization System
Through the drying and carbonization technology, the sludge can be reduced by 90%, and the carbonized products produced at the back end can be used as soil amendments, deodorants, dehydration aids, etc., to achieve resource utilization.
Drying Part: The sludge is crushed into 1-5mm particles size , directly blown by hot air at 150C.The discharge sludge moisture is 25%.
Carbonization part: External heating sealed pyrolysis system.The temperature is adjustable between 400-600 ℃C.In lack of Oxyger the generated H2,CO,Oils,syngas... are recovered and reused in the drying system, saving energy & operating cost.
Integrated drying and cabonization system.: igh-temperature tail gas from carbonizer is reused for drying reducing the energy consumption of dryer, then no needfor an independent emission treatment for the carbonizer.
