Abstract (en)
[origin: WO2012136225A1] The invention concerns a method for collecting petroleum products from a contaminated water surface, where pumice is used for laying upon a contaminated water surface. The new feature of a method according to the invention is that the pumice has an average particle size between 15 and 80 mm, preferably between 30 and 50 mm, where the pumice has a density between 200 and 400 kg/m3 by a water content below 10 weight-%. The particularly great advantage of pumice stones of this size is due to the fact that it has appeared to be much easier to collect the pumice stones when they have an appreciable dimension compared to that which has been previously used. At the same time, it is advantageous that the density is somewhat lower than the previously used types of pumice. The advantage of the lower density means that the pumice stones lie higher in the water surface, thus allowing the petroleum to attach to the surface and in the open pores of the pumice stones in a surprisingly efficient way.
