Slop Oil Recovery

Generate Profit from Slop Oil

In refineries all kinds of waste oils are produced – so-

called slop oils. They come from drainages, residues

and cleaning processes, especially cleaning oil tank

bottoms. Most of these slop oils contain a high per-

centage of oil which can be mixed with crude oil to

be processed in the refinery.

If this slop oil is treated, not only disposal costs can

be reduced but profit can also be generated with the

oil phase recovered from the slop. As the oil as well

as water content can vary from 10 to 90 percent and

the solid content can vary from 1 to 10 percent either

disk stack centrifuges or decanters can be used for

the treatment of slop oil.

Decanters are normally used for infeed with a solid

content of more than approx. 5 percent (by vol). A

disk stack self-cleaning centrifuge can be used down-

stream the decanter to polish either oil or water phase.

• 2-phase decanter to separate solids from liquid

phases

• Disk stack self-cleaning separator to separate the

two liquid phases. Here normally the oil phase is

the one to be cleaned. Optionally, the water phase

can be treated further downstream to avoid

disposal costs for oily water

• Oily water treatment systems from

GEA Westfalia Separator Group can reduce the

free oil content in water to up to 15 ppm

• As an alternative, 3-phase decanters are available

Exemplary scope of supply

3-phase decanters for the treatment of slop oil.

• No disk stack centrifuges for polishing the oil

phase as it is mixed with a high amount of crude

oil to be processed in the refinery

• Water phase polished in the already existing

water treatment plant

• Disposal costs only for solid content
