Slop oil treatment,
from tank to bilge

Mobile and fixed containerised REC plants: they treat slop oil and oily sludge where the waste is produced and recover the oil

Refineries and depots

The Gerotto robot enters via the manhole and extracts the sludge with no one inside, in ATEX Zone 0. A shaker, the RBT reactive tank and a three-phase Andritz decanter separate oil, water and solids

We treat
Slop oil, tank bottoms, crude oil, settling residues, API separator sediments, DAF sludge, desalter residues
Indicative flow rate
5-⁠15 m3/h for tank cleaning, about 7-⁠21 m3/h on crude oil
System
REC-OIL with Gerotto Lombrico robot
Tanker with tugboat on the open sea
02

Marine and ports

From the ship, via barge or storage terminal, bilge water flows from the reactive tank to the separation container. A high-speed separator polishes the outgoing oil

We treat
Bilge water and oily residues from ships under MARPOL Annex I, including at port reception facilities
Indicative flow rate
about 14-⁠40 m3/h
Output
Fuel oil with 0.1-⁠1% water and 0.1-⁠0.5% solids
System
REC-OIL with high-speed separator
Stacked drums of used and waste oil
03

Used oils

A three-phase Andritz decanter strips water and solids from used oils and returns the oil

We treat
Used oils with water and suspended solids
Indicative flow rate
about 12-⁠30 m3/h
Output
Oil with less than 2% water and less than 1% solids
System
REC-OIL
Oil containment booms on water contaminated by hydrocarbons
04

Remediation

Robots and suction units recover material from oil lagoons, basins and pits, while the floating skimmer collects the oil on the surface. Separation takes place on site, leaving less material to haul away

We treat
Lagoons and settling basins, pits, lakes contaminated by hydrocarbons
Indicative flow rate
1-⁠10 m3/h
System
REC-OIL with Gerotto robot and floating skimmer

Upstream

Spent drilling fluids and produced water treated right at the site, next to the well

We treat
Spent drilling fluids and produced water
System
REC-DRILL and REC-WATER
Output

Oil, water and solids,
each going its own way

<2%oil in the discharged water
<2%water in the recovered oil
>70%dry content in the solids

Indicative flow rates and yields: actual results depend on the product and the plant
