EVALUATION OF THE NON-OXIDATIVE THERMAL TECHNOLOGY FOR REMOVAL OF PETROLEUM PRODUCTS FROM CONTAMINATED SOILS
Journal Title: Present Environment and Sustainable Development - Year 2013, Vol 7, Issue 1
Abstract
The present paper illustrates results obtained at laboratory scale in order to assess the efficiency of the non-oxidative technologies used to decontaminate polluted soils. The experiments were carried out using a laboratory device: a calcinations oven, electrically heated, that operates in a discontinuous way. The soil samples used for the present research were collected from a real area contaminated with petroleum hydrocarbons. Experimental campaigns were conducted at different pyrolysis temperatures (350°C, 500°C, 650°C and 800°C) and focused on two main aspects: the influence of the process temperature on the decontamination efficiency and volatile quantity generated during pyrolysis treatment. The results of the experiments have shown that the process parameters have an important influence on the remediation of total petroleum hydrocarbons (TPHs) from contaminated soil. The efficiency of the pyrolysis treatment has significantly increased while process temperature has risen. It was observed the same order of magnitude on removing TPHs from soil when the pyrolysis time has been increased.
