Abstract:
A method for hydrothermal processing a feed material containing water soluble salts in a reaction chamber to inhibit a buildup of salts in the reaction chamber under supercritical water temperatures, the method comprising the step of:producing a reaction medium in the reaction chamber which contains a mono basic phosphate for transporting the salts through the reaction chamber, by providing an additive with at least a portion of the feed material, the reaction medium reaching supercritical water temperatures with a temperature of at least approximately 374.degree. C. and a pressure of at least approximately 25 bar in the reaction chamber, hydrothermally processing said feed material at said temperature and said pressure, and transporting said salts through said reaction chamber.
