Abstract:
An effluent handling method for use in a supercritical water oxidation treatment system, the effluent handling method comprising the steps of:(a) receiving a solids laden effluent from the supercritical water oxidation treatment system and reducing the pressure of the solids laden effluent to a gas phase pressure at which a significant gas phase exists with a solids laden liquid phase;(b) containing the solids laden liquid phase and gas in a vessel at the gas phase pressure;(c) maintaining the gas phase pressure in the vessel and allowing gas to exit the vessel to maintain the gas phase pressure;(d) periodically placing a two-position liquid removal valve in a fully open position to remove solids laden liquid from a bottom of the vessel so as to maintain a liquid volume in the vessel below a maximum liquid volume value, and maintaining the two-position liquid removal valve in fully closed position when not in the fully open position.
