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

Abstract

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.
