6. Problems of Oil Spill CombatingProblems of Oil Spill Combating
1. How to collect the oil
Oil is usually skimmed off from the water surface by special
skimming systems. There are a variety of different skimmer
types and systems available.
2. How to separate the oil from the water
Water is the carrier medium for the oil. All skimming systems
collect sizeable quantities of water along with the oil. The
oil/water mixture collected by the skimmers contains only about
15 to 20% oil, 50% at most. Hence, storage tank capacities are
easily filled.
The solution is separating the oil from the water and storing only
the oil in the tanks, while the water is discharged.

The Solution: Separate the oil from the water, so that
only the oil is stored, while the water may be discharged.

11. Oil/Water Separation SystemsOil/Water Separation Systems
Technomar offers oil/water separation systems in the following forms:
Firmly installed separation systems
aboard oil spill combating vessels
Compact separation units with the
dimensions of a standard ISO 20‘
container for greater mobility

14. CoalescenceCoalescence
The separation process utilizes the physical principle of coalescence on
oleophile surfaces.
Coalescence means that small oil
droplets adhere to oleophile surfaces
and form bigger oil drops.

Technomar separation
systems contain
coalescence elements like
the ones in the photo above.

15. SEPCON UnitsSEPCON Units
SEPCON units are compact oil/water separation systems with the
dimensions of a standard ISO 20‘ container. SEPCON units are designed for
mobility and may be employed wherever needed. Every SEPCON unit is
equipped with a diesel engine and therefore independent of outside power
supply. Throughput: 80 m³/h
Length: 6.06 m = 20 ft
Width: 2.44 m = 8 ft
Height: 2.59 m = 8.5 ft
Weight empty: 10 000 kg
Weight full: 25 000 kg
Max. oil content: < 50%
Max. viscosity: 70 000 cSt
Max. density: 0.99 g/m³
Flashpoint: > 60°C
SEPCON units separate oil and water in a direct
throughflow process, utilizing only the physical
principles of gravity and coalescence. Chemical
additives and long settling periods are not
necessary.

16. SEPCON 40SEPCON 40
The smaller SEPCON 40 unit was built for the German federal disaster
relief agency THW.
Throughput: 40 m³/h
Length: 6.06 m = 20 ft
Width: 2.44 m = 8 ft
Height: 2.59 m = 8.5 ft
Weight empty: 9 000 kg
