Abstract

This report presents the work of thermal treatment of marine soil contaminated with hydrocarbon. The aim of the project is to determine the optimum temperature and to find the efficiency of thermal treatment in removing hydrocarbons contaminated in marine soil with different penetration depths of the contaminated marine soil. Marine soil pollution normally is contaminated with hydrocarbon through many operations in petroleum exploration, production and transportation. In long term, the organic hydrocarbons have resulted in major environmental issue because of their adverse effect on human health and environment. The contaminated marine soil must be treated to avoid the problems. There are four categorizes of treating technologies available: chemical & physical treatments, biological treatments, solidification I stabilization and thermal treatments. Normally the treatment method has been chosen based on the efficiency of the treatments. In the study, the soil samples were collected .frotn one of the marine site in Malaysia with the different depth penetrations (surface area, I Ocm, 20cm, 30cm, 40cm and 50cm) and were placed in the glass containers fitted with plastic screw lids. The contaminated soil analyzed to determine the hydrocarbon groups contaminated using the Gas Chromatography Mass Spectrum Unit (GCMS) and treated through thermal treatment method using Fixed Bed Activated Unit. The temperatures were used are 300"C, 400"C, 500"C and 600"C, with the residence time of 94 minutes. The amounts of hydrocarbon removing/reducing from the contaminated soil have been measured by UVNisible Spectrophotometer. The efficiency of the thermal treatment method has been calculated based on the amount of hydrocarbon removal from the contaminated soils. After categorize these hydrocarbons into groups, the optimum temperature of the treatment have been found. The result show that the thermal treatment method on the samples which have 76% containing hydrocarbon from alkanes group with their carbon chains between Cz to Czo very efficient in removing hydrocarbon contaminants in the contaminated soil. The optimum thermal treatment temperature was obtained about 300°C.
