ROCCO™ Slop

Motiv, namn på personer mm

As the compositions in slop oil and industrial emulsions can vary within wide ranges our plant design makes it possible to handle various grades of slop oil and emulsions in the same process/plant. ROCCO Slop Oil Plant works as an “oil recovery hub” for the industry – a fully integrated process plant, using Double Separation Technology (DST). The plant can be built in a variety of sizes. Processing volumes range from 10 000 tons and upwards.

Slop Oil Potentials

Today’s market for slop oil is fragmented and uses low tech solutions for cleaning, mainly mechanical cleaning in conjunction with heat. RecondOil’s technology improves the process dramatically:

  • Reduces the processing time.
  • Results in cleaner fractions and a larger volume of the most important end product; oil for re-refining and/or energy recovery.
  • Makes it possible to handle various grades of slop oil and emulsions in the same process/plant.

A global environmental problem

 oljehav

Low quality residues (Slop Oils) are a global environmental problem found wherever oil is being drilled, refined, transported or stored. It is a generally agreed on fact that theses residue products an slop oils cannot be refined directly without first under going some sort of processing. This is because one or more of the technical / chemical parameters possessed by these oils are often beyond the maximum limits specified and allowable for raw products to be refined.

There is a serious need for technologies to process these low-quality residual oils. With an continuously increasing price of crude oil these slop oils represents big values!

What is slop oil?

slop-smallSlop(s) as defined in the dictionary states ”liquid refuse” or ”spilt liquid”, therefore a slop tank/pond will be a convenient place to store all waste products, especially products which could not be separated by conventional methods.

By definition slop oil treatment is one of the most technically demanding applications for separation technology. Originating from many sources, slop oils vary widely in composition and physical properties. One common factor is that they contain both water and solid impurities, coarse as well as fine. In addition, the oil and water frequently form a very tight emulsion, often stabilized by fine particle contamination, therefore a typical slop oil will consist of four phases. These wastes or slop oils are useless without special processing, and are expensive in terms of storage, disposal, and can be very environmentally unfriendly, especially if stored in a pond open to atmosphere. This variability of the feedstock is one of the key problems when trying to reliably achieve an effective and efficient separation of the solid, aqueous and oil phases.

Our plant design allows, as far as is practicable, for changes in the feedstock composition whilst assuring the highest quality and quantity of recovered oil. The primary objective of the plant is to recover oil that can either be directly marketed as a valuable product or passed to a refinery for further processing, the second objective is to solve an environmental problem by processing the contents of a slop oil pond.

Slop Oil can consist of the following:
0 – 100% Oil
0 – 100% Emulsion
0 – 100% Water
0 – 60% Solids

Waxes are also present, which usually dictates the necessity to process at high temperatures (+70oC).
Slop Oil can originate from many sources.

This make Slop Oil treatment into one of the most technically demanding applications for separation technology.
