About Slop Oil
Slop oil is a complex mixture of hydrocarbons (oil), water, and solid contaminants generated during petroleum refining, storage, and transportation processes. It typically accumulates in oilwater separators, storage tank bottoms, lagoons, and wastewater systems.
This material is often considered a waste or off-spec product stream because it does not meet refinery product standards. However, it still contains valuable hydrocarbons that can be recovered and reused through treatment processes.
Slop oil is also referred to as:
- Oily sludge
- Rag layer
- Waste oil residue
It is an emulsified system, meaning oil, water, and solids are tightly mixed, making separation and processing technically challenging.
