Electro Thermal Dynamic Stripping Process (ET-DSP) is a patented in situ thermal environmental remediation technology, created by McMillan-McGee Corporation, for cleaning contaminated sites. ET-DSP uses readily available three phase electric power to heat the subsurface with electrodes. Electrodes are placed at various depths and locations in the formation. Electric current to each electrode is controlled continuously by computer to uniformly heat the target contamination zone.〔(McMillan-McGee Corp. )〕 ==Difference between ERH and ET-DSP== The difference between Electrical Resistance Heating (ERH) and ET-DSP is heat transfer due to convection. Water injected around the ET-DSP electrodes is heated and flows radially toward the vacuum extraction wells heating the formation in the process. The difference between ERH and ET-DSP is shown in the governing equations. The governing equation for Electrical Resistance Heating (ERH) is given by, where is the bulk heat capacity of the formation, T is the temperature, t is the time, is the thermal conductivity, is the electrical conductivity, I is the electric current and L is the electrode length. The governing equation for Electro Thermal Dynamic Stripping Process (ET-DSP) is given by, where is the density of water, is the specific heat of water and Q is the water injection rate. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Electro Thermal Dynamic Stripping Process」の詳細全文を読む スポンサード リンク
