Abstract
The objective of this study is to remove BTEX(Benzene, Toluene, Ethylene, Xylene) and TPH(Total Petroleum Hydrocarbon) effectively by using method low thermal desorption. The thermal desorption is frequently selected because it can treat various contaminants effectively. The temperature and heating time are determined by TGA(Thermogravimetric analysis) curve. The experiment result from this research, removal rate of BTEX was up to 100% within 5 minutes and removal rates of TPH were more than 65% at $300^{\circ}C$ and 70% at $500^{\circ}C$ respectively. It was observed that there was a little change of removal rates of TPH.
