This paper summarizes the author's previous studies on the sorption of hydrocarbons in sandy soils. Completed several independent series of measurements for various models of soil. There were used unleaded petrol and diesel fuel as petroleum products. A large amount of collected information allows you to draw some interesting conclusions, which may be the basis for generalizations. The detected regularity can afford to develop a several models that can be successfully used to describe the intensity of hydrocarbon sorption processes in soils. These processes have a significant impact on the hydrocarbon migration in the soil by reducing the pollution zone and extending the time of migration. Inaccurate description of the magnitude sorption capacity will lead to large differences between the actual scenario of hydrocarbon migration in soil and its numerical simulation.

Thanks realized in 2011 in a wide range of laboratory investigations of adsorption of selected petroleum products in different models of soil author has an extensive set of experimental data. They lead to a series of qualitative and quantitative analysis. They confirm the generally known fact that the intensity of the adsorption of hydrocarbons strongly depends on some features of the oil products (mainly viscosity) and soil (especially grain). It is possible to fit the regression equation using statistical methods, which permits to estimate the adsorption coefficient of different oil products on the basis of parameters describing the granulation of soil. Those obtained equations are characterized by a high degree of suitability to the experimental data and can be successfully used in numerical modeling of hydrocarbon migration in the soil.

W trakcie budowy laboratoryjnego stanowiska pomiarowego do badania migracji substancji ropopochodnej w gruncie na podstawie badań bezpośrednich określono wybrane właściwości materiałów użytych do wykonania fizycznych modeli gruntu niespoistego. Bazując na tych parametrach, dokonano prognozowania współczynnika przepuszczalności z wykorzystaniem wybranych, ogólnie uznanych modeli petrofizycznych. Otrzymane oceny porównano z wynikami badań laboratoryjnych zrealizowanych na stanowisku pomiarowym do określania przepuszczalności dla powietrza. Bazując na kruszywach wykorzystanych do wykonania modeli gruntu, przygotowano do pomiaru dla każdego przypadku dwa modele ośrodka porowatego: dla luźnego i zagęszczonego ułożenia ziaren

During construction of the laboratory position for research of migration of petroleum hydrocarbon substances in soil, was found chosen properties of materials used to made of physical soil models, on base of direct laboratory research. It predicts of permeability ratio used these parameters and generally recognized petrophisical models. It compares received estimates with results of laboratory research realized on measuring position for finding of absolute permeability for air. For each soil model two models of porous media were prepared for loose and condensed grain laying
