Abstract: Method for cleaning a material contaminated with an organic pollutant by heat treatment, where energy for heating the material is provided by direct heat treatment of the material in a hammermill. An organic polar additive with a boiling temperature above 100° C. is added to and mixed with the material prior to the direct heat treatment. A use of the organic polar additive is described as well.

Abstract: A method is for thermal separation of a non-polar organic compound from a material by steam distillation, where microwave radiation provides energy to the material, and where a susceptor comprising an organic substance with an electric dipole characteristic is added to and mixed with the material prior to the steam distillation, and the susceptor contributes with vapor to the steam distillation. Use of the susceptor in a steam distillation process is described as well.

Abstract: The invention concerns, among other things, a precipitating chemical for separating preferably hydrocarbons from water, but also for separating other dissolved and/or suspended organic and/or inorganic substances and particles in an associated liquid, including mineral and/or rock particles, heavy metals, salts, phosphorous compounds, alcohols, lipids, aromatics and cellulose. The precipitating chemical is composed of bentonite, preferably sodium montmorillonite; of polymer, preferably of the polyacrylamide type; of sodium polyphosphate and/or lignite; and of water. The chemical is added to and mixed with waste liquid, after which chemical precipitation is activated through the addition of acid or base until the pH-value of the liquid mixture is 4.0 or less, or the pH-value being 8.0 or more. The liquid mixture then rests until the contaminant(s) flakes and separates from the liquid phase of the mixture and is then deposited or floated from the liquid mixture.
