Abstract
Official abstract text for this publication.
In a method for recovering volatile components from a solid material, a liquid phase is mechanically removed from the solid material. Subsequently, the solid material is dried by exposing the solid material to superheated steam circulating in a closed circuit. From the closed circuit excess steam that contains volatile components given off by the solid material is removed. The volatile components are separated from the excess steam by condensing the excess steam to a condensed phase and the volatile components are from the condensed phase by adding suitable ions to the condensed phase to crystallize the volatile components.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for recovering volatile components from a solid material, the method comprising the steps of: removing a liquid phase mechanically from the solid material; subsequently drying the solid material by exposing the solid material to superheated steam circulating in a closed circuit; removing from the closed circuit excess steam that contains volatile components given off by the solid material; separating the volatile components from the excess steam by condensing the excess steam to a condensed phase and recovering the volatile components from the condensed phase by adding suitable ions to the condensed phase to crystallize the volatile components. 2 . The method according to claim 1 , wherein the solid material is of organic origin and the volatile component is ammonia. 3 . The method according to claim 1 , wherein the solid material is of organic origin and is subjected to a biological pretreatment prior to drying. 4 . The method according to claim 3 , wherein the biological pretreatment is anaerobic.
