Comparative studies on remediation techniques in laboratory of soils contaminated with liquid petroleum products

Soil pollution by oil products is one of the most obvious environmental problems that Romania
has been facing in recent years. Given the alert pace of use of petroleum products and for
meeting energy needs, it is noted that both in Romania and abroad there are reported
accidental oil spills to soil or water, which causes economic, social and environmental issues.
In this paper we propose a review of the particularities of soil pollution with liquid petroleum
products and opportunities for remediation. The analysis of remediation processes of soils
contaminated with liquid petroleum products highlights the advantages and disadvantages of
each method. The analyzed samples were subjected to thermal remediation methods:
combustion and thermal desorption and one of the chemical processes, succesive extraction
with solvents.
The results of these experimental data allow us to conclude that the used method is efficient
and can be applied at industrial level with high efficiency.
