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 thatonly the oil is stored, while the water may be discharged.
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

CoalescenceCoalescenceThe separation process utilizes the physical principle of coalescence on oleophile surfaces.
Coalescence means that small oildroplets adhere to oleophile surfacesand form bigger oil drops.

Technomar separationsystems contain coalescence elements likethe ones in the photo above.
SEPCON UnitsSEPCON UnitsSEPCON 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

Max. oil content: < 50%Max. viscosity: 70 000 cStMax. density: 0.99 g/m³Flashpoint: > 60°CSEPCON 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.
