Sub-Product

In upstream and downstream Processes all kinds of Waste Oils / Sludge are produced, the so-called Slop Oils or “Oily Sludge.

These Streams are generated from Residues and Processes, such as:

• Oily Sludge from DAF Units
• Bottom Sediments from API Separators
• Lagoons and Oil Pits 
• Tank Bottoms
• Desalter of Spec Products
• Marpol Sludge

The Slop Oils can have variations in their composition and can contain 10 – 70 % Oil, 30 – 90 % Water and 5 – 20 % Solids. The oil viscosity can be very high and reach values of up to 1000 cSt / 50°C. The Specific Gravity of the Oil (Oil density) can vary from 0.8 to 0.98 g/ml. In addition, low pH values and high Chloride concentrations are other challenges. Furthermore, other factors such as abrasive particles (Sand), Organic Dolids and the presence of Asphaltenes must be taken into account. Unless this Sludge is treated on-site, it either has to be incinerated, or sent to specialized Treatment Plants for further processing / disposal. Since this Waste is also hazardous to the environment and difficult to transport, it is costly to dispose for the Oil industry, driving a high demand for services that are able to process Oily Sludge in an efficient manner. Slop Oil Treatment also recovers Hydrocarbons
that would otherwise be lost, generating additional value.
