DESORPTION OF HYDROCARBON CONTAMINANTS IN SOIL AND WATER USING ELECTROMAGNETIC (EM) HEATING

1990年至2012年间，仅在阿尔伯塔省，就有大约648万升碳氢化合物液体泄漏到土壤和水中。利用氧化性化学物质处理土壤中的碳氢化合物污染物在高温和低温条件下往往效果不佳，导致土壤二次污染。汉纳塔工业有限公司和卡尔加里大学已经形成了一项研究合作，研究和开发成本效益和节能技术，利用电磁加热处理土壤和水中的碳氢化合物污染物。

Roughly 6.48 million liters of hydrocarbon liquids have leaked onto soil and water between 1990 and 2012 in Alberta alone. Treatment of hydrocarbon contaminants in soil using oxidizing chemicals often fall short at high and low temperatures leading to secondary pollution of the soil. Hanalta Industries Ltd. and the University of Calgary have formed a research collaboration to investigate and develop cost-effective and energy-efficient techniques to treat hydrocarbon contaminants in soil and water using Electromagnetic heating. A novel electromagnetic open probe test setup will be developed to measure Electromagnetic field propagation and transduction into heat within different mixtures of hydrocarbon-contaminated soil and water as a function of frequency and environmental conditions. Optimal frequency bands for Electric and Magnetic fields used to heat of hydrocarbon-contaminated soil and water will be determined, and a wireless transmitter test system to irradiate and desorb hydrocarbon contaminants from contaminated soil and water samples will be developed at those optimal frequencies.
