Slop Oil and Oily Sludge Recovery Technology

The process is configured around six treatment functions: de-emulsification and solids removal, demetallization, oil-water separation, water purification, nano-scale de-emulsification and vacuum drying or thermal desorption. The overall objective is reduction, harmless treatment and resource recovery, with recovered products directed to reuse or further processing where applicable.

Typical integrated treatment flow for oily liquids, sludge and wastewater

Typical Feed Sources

Oily sludge from oil and gas exploration and production

Oil sludge generated during oil transport

Oily sludge from refinery operations

Oily wastewater and sludge requiring oil recovery, water reuse or compliant discharge

Key Features & Benefits

Integrated six-stage treatment

Combines oil recovery, water purification, metal removal, solids treatment and thermal reduction in one coordinated process route.

 

Closed and continuous first-stage operation

The 1D de-emulsification and solids-removal step operates as a sealed, continuous process, with no wastewater, waste gas or solid waste discharged from this stage.

 

High separation and purification performance

The process separates oil, water and solids, and further purifies the recovered water and oil phases.

 

Resource recovery and waste reduction

Purified oil and water can be recovered for reuse or further processing. Drying and thermal treatment reduce the amount of residual material requiring further handling.

Treatment Process Stages

1D - De-emulsification and solids removal

Cyclonic centrifugal separation breaks the stable oil-water-solid structure and removes dense solids.

 

2D - Demetallization

Chemical treatment removes metal compounds from the treated material.

 

3D - Enhanced-gravity purification

Physical separation produces purified oil, purified water and solid residue.

 

4D - Micro-interface reaction

Micro-interface treatment further purifies the water phase by removing dispersed contaminants.

 

5D - Nano-de-emulsification

A nano-de-emulsification unit removes trace oil droplets from the water phase.

 

6D - DSMVR drying and thermal desorption

Vacuum drying reduces water and sludge volume. Where required, thermal desorption further removes oil from the dried residue.
