Application of carbon dioxide in the remediation of soil, sediment and contaminated aquifers

摘要

A method for soil remediation comprising the injection and / or diffusion of carbon dioxide used as solvent pollutants are transported in this manner in the topsoil, the method being characterized by the following additional steps: - digging and removal of the surface layer in which all the contaminants are concentrated; - recovery and reuse of CO2 by control systems capture and removal by suction and / or pressure; - CO2 purification extracted in order to remove particulates, moisture, and gases entrained contaminant fraction.
