Resumen de: BE1032893A1

La présente innovation se focalise sur un procédé visant à nettoyer les eaux souterraines renfermant des substances polluantes ayant une densité inférieure à 1g/cm³, tels que les hydrocarbures. Cette proposition présente une méthode novatrice pour éliminer la couche de contaminants flottants en se basant sur la technologie d'écrémage. Le procédé consiste à chauffer la zone saturée contaminée jusqu'à atteindre la température requise, pendant une durée adéquate pour réduire la viscosité des contaminants constituant la couche flottante. La technologie d'écrémage se concentre sur l'extraction précise de cette couche flottante. La présente invention vise à conjuguer l'utilisation de l'énergie solaire pour chauffer les contaminants présents dans la couche flottante de la zone saturée, avec la méthode d'écrémage. Ceci vise à optimiser le temps de traitement de la zone saturée en chauffant les contaminants, augmentant ainsi leur mobilité pour faciliter leur extraction par écrémage.

Resumen de: US20260071762A1

A geothermal system exchanges heat between a target and ground which receives geogenic heat from below. Heat exchange tubing in a continuous loop within the ground receives a circulated heat exchange fluid. An insulating layer spans over the ground with a greater footprint than the continuous loop in the ground below. The insulating layer may cover an area of land of at least 400 square metres and may be formed of a synthetic heat insulating material such as recycled plastic materials so that the insulting layer has a total R factor of 30 or greater. A heat pump is operable to transfer heat from the heat exchange tubing to the target for extracting the geogenic heat from the ground for heating the target in cold seasons, and transfer heat from the target to the heat exchange tubing for storing excess heat from the target to the ground in warmer seasons.
