Modelling of diesel fuel penetration depth in protective sand bed

Abstract

When deploying a temporary fuel storage warehouse, the primary source of soil contamination by oil products is technological losses related to the leakage of isolation valves. To protect the soil from contamination, containers are placed on a layer of sand. The thickness of the sand layer depends on the volume of possible losses. The purpose of the work is to model the depth of diesel fuel penetration into the protective layer of sand bed. The method of performing the experiment imitated a high rate of fuel penetration in the form of droplets onto the protective layer. The article considers the mechanism of fuel penetration into sand and factors, determining the penetration depth. It is established that the mechanism of fuel penetration into the protective layer has two stages, on each of which the penetration depth and rate of fuel distribution are different. The maximum penetration depth is reached on the first stage and depends on the quantity of fuel. The author developed the model, which allows the determination of the thickness of the sand bed protective layer with known granulometric particle composition necessary for the prevention of diesel fuel penetration into soil.
