  6. 6. Problems of Oil Spill CombatingProblems of Oil Spill Combating1. How to collect the oilOil is usually skimmed off from the water surface by specialskimming systems. There are a variety of different skimmertypes and systems available.2. How to separate the oil from the waterWater is the carrier medium for the oil. All skimming systemscollect sizeable quantities of water along with the oil. Theoil/water mixture collected by the skimmers contains only about15 to 20% oil, 50% at most. Hence, storage tank capacities areeasily filled.The solution is separating the oil from the water and storing onlythe oil in the tanks, while the water is discharged.

  14. 14. CoalescenceCoalescenceThe separation process utilizes the physical principle of coalescence onoleophile surfaces.Coalescence means that small oildroplets adhere to oleophile surfacesand form bigger oil drops.Thecoalescenceprocess seenunder themicroscopeTechnomar separationsystems containcoalescence elements likethe ones in the photo above.
  15. 15. SEPCON UnitsSEPCON UnitsSEPCON units are compact oil/water separation systems with thedimensions of a standard ISO 20‘ container. SEPCON units are designed formobility and may be employed wherever needed. Every SEPCON unit isequipped with a diesel engine and therefore independent of outside powersupply. Throughput: 80 m³/hLength: 6.06 m = 20 ftWidth: 2.44 m = 8 ftHeight: 2.59 m = 8.5 ftWeight empty: 10 000 kgWeight full: 25 000 kgMax. oil content: < 50%Max. viscosity: 70 000 cStMax. density: 0.99 g/m³Flashpoint: > 60°CSEPCON units separate oil and water in a directthroughflow process, utilizing only the physicalprinciples of gravity and coalescence. Chemicaladditives and long settling periods are notnecessary.
