Mobil Unit for Slop Oil Treatment Sludge and Chemical Recovery

Slop Oil Turns Into Profit

“Slop oil” or “oily sludge” are waste oil and sludge produced in both upstream and downstream processes.

Many of these resources contain a high percentage of oil that can be recovered as valuable products; the economic and environmental contribution of reduced waste volumes should not be overlooked. This trash is costly to dispose of for the oil industry because it is both environmentally harmful and difficult to transport. Due to this, there is a great need for services that can effectively handle oily sludge. Slop oil treatment additionally adds value by recovering hydrocarbons that would otherwise be lost.

Solution for Slop Oil Recovery

Unique process solutions

Depending on the type of slop oil, both disc and decanter centrifuges are used. The self-cleaning disc separators in the downstream process carry out the cleaning of the aqueous or oily phase. Three-phase single-stage decanter centrifuges are the perfect option if the starting material allows efficient dehydration with simultaneous separation of oil and water in one stage.

2-stage treatment

The 2-stage treatment becomes the most practical process solution when the raw material is more difficult to treat or when the oil quality specifications are tighter. The ultra-fine particles are separated by high-speed disc stack machines that process the core phase of the decanter while simultaneously removing as much water as possible.

3-stage treatment

Oxint with Polat Makina also has the know-how to offer the most sophisticated 3-step treatment procedure with an additional treatment step for water purification (oil removal of the aqueous phase). For processes or areas where water treatment is needed, this can be an alternative.

Some specific sectors of origin of slop oil:

The Cow System

Crude oil washing (COW) is a system whereby oil tanks on a tanker are cleaned out between voyages not with water, but with crude oil – the cargo itself. The solvent action of the crude oil makes the cleaning process far more effective than when water is used. (There is usually a final water rinse but the amount of water involved is very low.) The system helps prevent pollution of the seas from operational measures.
Crude oil washing was made mandatory for new tankers by the 1978 Protocol to the MARPOL Convention. Regulation 33 of MARPOL Annex I requires every new crude oil tanker of 20,000 tons deadweight and above to be fitted with a cargo tank cleaning system using crude oil washing.
Regulation 33 states that COW installation and arrangements should comply with at least all of the provisions of the Specifications for the Design, Operation and Control of Crude Oil Washing Systems adopted by IMO in 1978, as may be revised.
In 1999, IMO adopted revised specifications for COW by resolution A. 897(21) Amendments to the revised Specifications for the Design, Operation and Control of Crude Oil Washing Systems (Resolution A.446(XI), as amended by resolution A.497(XII).
