ABSTRACT:
The method of separating impurities from an aqueous solution by means of rotating the aqueous solution at high speeds until a high pressure and a high temperature is reached. At that time the impurities are separated from the solution. The aqueous solution is kept at high temperatures and pressures until the impurities are separated from the liquid. Preferably, a device providing a centrifugal force, such as a centrifuge, is used to achieve the high temperatures and pressures which should preferably be no lower than 705.4.degree. F. and 3,208 psi, respectively.
