Способ определения эффективности диспергентов для ликвидации аварийных разливов нефти в ледовых морях
FIELD: ecology.SUBSTANCE: method for to determination of dispersants efficiency includes recording of the physical parameters when the phase of the liquid sample being examined and placed in containers is changed. During method implementation, at least four containers are filled with liquid at the same time, then oil products and a portion of dispersant applied dropwise are successively applied to the liquid surface in each container. Then the containers are shaken for a time equal to the natural dispersion time for petroleum products in the test liquid, and the contents of the containers is shock-frozen until it freezes completely. The frozen contents of the containers are then separated by two horizontal cuts into the upper, middle and bottom blocks. The middle and bottom blocks are removed from the container shell, and the resulting ice samples are melted and filtered separately. After that, the mass of the filtered residue of oil products obtained from each sample is measured. The dispersant efficiency of the is determined by the ratio of the weight of the filtered oil product to the total mass of oil products in the mixture placed in the test vessel, taking into account the natural dispersion determined at the zero stage of testing, where at the zero stage of testing, the natural dispersion of oil products in the thickness of the liquid sample to be examined is determined at least to the middle zone of test capacity and natural dispersion time.EFFECT: increased accuracy and speed of dispersants efficiency determination.2 dwg, 1 ex
