A contaminant extraction system has been disclosed for a material containing a soluble contaminant, comprising; an elongate housing and a pressurised treatment chamber Iocated within at least part of the elongate housing. The treatment chamber has a closeable inlet and a closeable outlet, whereby the closeable outlet is spaced apart from the closeable inlet. At least one further inlet is provided for enabling the insertion of a fluid into the treatment chamber. The fluid is sustainable in a solvent state so as to enable extraction of the soluble contaminant. A pressure controller is also provided for maintaining the pressure within the treatment chamber at a predetermined value so as to maintain the fluid in the solvent state. |
