Refinery Waste Remediation
MUEG has developed and applied treatment processes to solve and
prevent problems of refinery waste (acid tar, tar and oil sludge).
MUEG has tested various methods to treat refinery waste material after
excavation. The common goal was and is not only the sustainable
remediation of the site but the environmentally friendly handling and
utilisation of the refinery waste as well.

Sampling / Site Investigation
Main targets: sampling at different locations at different depths to obtain
representative material of contaminated sites like tar, acid tar and oil sludge lagoons
Two methods are possible depending on circumstances and available equipment:
1. Use of a pontoon and drilling equipment
2. Use
Sampling and Investigation of Contaminated Sites/ Deposits
of an excavator
Acid tar sampling with excavator
Romania, Acid Tar Lagoon (2006)
Sampling with pontoon and drilling
Equipment, Acid tar lagoon (2010)
Sampling with excavator,
Acid tar lagoon, Scandinavia (2008)

Mixing unit for material tests,
“Eirich Mixer”
Test for incineration
Tests for incineration in power plants
MUEG laboratory
Test material: -
Additives: -
liquid, muddy (viscous) or solid
acid tar
possible: tar, oil sludge etc.
for conditioning of the material
to a secondary fuel
→ conditioning in a closed mixing unit
→ production of substitute fuel
(under laboratory conditions)
Necessary for determination of the
best recipes!

Recovery with tower crane by MUEG
Excavation technologies
Recovery with excavator by MUEG Recovery with slurry pump
Remediation Process
Recovery of tar, acid tar or oil sludge
material depending on the consistency:
- with tower crane
- with excavator technology
- with slurry pump
The recovery technology largely determines
the success of the treatment process!

Excavation/ separation of harmful substances
(drums, tyres etc.), acid tar project in Germany
Handling of Harmful Substances
Harmful Substances
Harmful substances
- demolition waste (brick, metal, concrete, wood,
and plaster board etc.)
- household and commercial waste, like
drums (plastic, metal) with hazardous waste,
wood residues, glass, metals, plastic etc.
- old car bodies
- munitions and explosives
-etc.
Handling
- excavation of waste material
- separation of waste material
- cleaning of the harmful substances
- separate storage in containers
- transport for recovery / disposal
- environmentally friendly recycling

Thermal / Energetic
Utilisation
Delivery of substitute fuels to the power station
Delivery control system – Bunker equipment – Feed system to coal boilers (2 x 900 MW)
Since 2002 MUEG has operated a truck unloading station
at Schwarze Pumpe to supply annual quantities of up to
420,000 tons of its own substitute fuels, derived from acid
tar and other waste, to the brown coal boilers of the
power station for thermal utilisation.
The substitute fuel can also be burnt in cement kilns if
they have the appropriate technological conditions (such
as Latvian acid tar remediation project).

Recovery
(emission reduced)
Also possible for:
Tar, Oil Sludge
Acid Tar
Lagoon
Remediation Concept
Elimination of acid tar from lagoons – Qualified concepts
Treatment of substitute fuel
Mobile treatment plant with gas
cleaning system
(neutralization / solidification)
Transport by
truck or railway
Contaminated soil, harmful substances etc.
Treatment on-site and/or disposal on landfill
- separation, if necessary on-site treatment
(such as thermal desorption, microbiological treatment)
Energetic utilisation
(power plant- or cement kiln)
- comprehensive experiences
- qualified and existing approvals
