Termisk assisterede oprensninger

Appendiks 3:
Patenter

Hovedparten af de amerikanske patenter er nationale, dvs. ikke gældende for Europa. Her er en liste over de vigtigste:

Lawrence Livermore National Laboratory, Livermore, Californien:

US Patent # 5,495,175-Using Electrokinetic Phenomena and Electrical

Resistance Tomography to Characterize the Movement of Subsurface Fluids.

US Patent # 5,346,307-Using Electrical Resistance Tomography to Map Subsurface Temperatures.

US Patent # 5,449,251-Dynamic Underground Stripping: Steam and Electric Heating for In Situ Decontamination of Soils and Groundwater.

US Patent # 5,325,918-Optimal Joule Heating of The Subsurface.

US Patent # 5,681,130-Active Cooling-Based Surface Confinement System For Thermal Soil Treatment.

Desuden har LLNL et internationalt patent på vej for Hydrous Pyrolysis: Thermisk accelereret oxidation af organiske stoffer ved tilførsel af ilt. Dette vil ikke berøre en eventuel anvendelse af termisk assisteret oprensning i Danmark, som beskrevet i denne rapport.

Pacific Northwest National Laboratory, Richland, Washington:

US Patent # 5,316,411-Apparatus for In Situ Heating and Vitrification.

US Patent # 5,347,070-Treating of Solid Earthen Material and a Method for Measuring Moisture Content and Resistivity of Solid Earthen Material.

US Patent # 5,545,803-Heating of Solid Earthen Material, Measuring Moisture and Resistivity.

EPC 92925177.5. Dette patent omfatter de to ovenfor, og er gyldigt i Europa. Patentet omfatter 6-faset elektrisk opvarmning og samtidig bestemmelse af jordens resistivitet og fugtighed.

PNL har derudover ingen internationale patenter af betydning for termisk assisteret opvarmning i Dammark.
