Cleaning of contaminated soil or sand by Crude Oil
The situation
• Beaches are being polluted more and more frequently by hydrocarbon waste, either following accidents when transporting oil cargoes or after tankers have cleaned out tanks at sea.
• Environmental constraints make it necessary after accidental pollution to clean contaminated soil as quickly and effectively as possible.
• Until now, sand has merely been riddled, thus removing pollution only abouve a certain size. The cleaning operations performed on beaches turn out to be unsatisfactory concerning the quality of the sand once it has been cleaned.
• Hydrocarbon pollution can also take place on land.
• Thus, there are many sites that have been polluted, either by leaks from storage tanks or from pipes for conveying oil such as pipelines, or indeed from industrial installations.
The technology – workflow
• Transport of the polluted soil or sand to the cleaning-machine
• Feeding the cleaning-machine with the polluted soil or sand
• Crushing by special machine of the polluted material for parts preferably with a size less than 10 mm
• Transport of the crushed polluted material into the cleaning-machine where the polluted material will be mixed with the Activator
• In the following additional mixture with an aqueous solution
• Separation of the hydrocarbons, the involved water and the fine particles in the sediments
• Transportation of the depolluted soil / sand in separate container and skimming of the equally cleaned hydrocarbons in special container for waste disposal, or for the use of diesel generators or better for selling to refineries.
