Title: Process for treating effluent from a supercritical water oxidation reactor

Full Record
Other Related Research

Abstract

A method for treating a gaseous effluent from a supercritical water oxidation reactor containing entrained solids is provided comprising the steps of expanding the gas/solids effluent from a first to a second lower pressure at a temperature at which no liquid condenses; separating the solids from the gas effluent; neutralizing the effluent to remove any acid gases; condensing the effluent; and retaining the purified effluent to the supercritical water oxidation reactor.

Containment system for supercritical water oxidation reactor

Patent Chastagner, Philippe [3134 Natalie Cir., Augusta, GA 30909-2748]

A system for containment of a supercritical water oxidation reactor in the event of a rupture of the reactor. The system includes a containment for housing the reaction vessel and a communicating chamber for holding a volume of coolant, such as water. The coolant is recirculated and sprayed to entrain and cool any reactants that might have escaped from the reaction vessel. Baffles at the entrance to the chamber prevent the sprayed coolant from contacting the reaction vessel. An impact-absorbing layer is positioned between the vessel and the containment to at least partially absorb momentum of any fragments propelled bymore » « less

Method and apparatus for treating gaseous effluents from waste treatment systems

Patent Flannery, Philip A [Ramsey, MT]; Kujawa, Stephan T [Butte, MT]

Effluents from a waste treatment operation are incinerated and oxidized by passing the gases through an inductively coupled plasmas arc torch. The effluents are transformed into plasma within the torch. At extremely high plasma temperatures, the effluents quickly oxidize. The process results in high temperature oxidation of the gases without addition of any mass flow for introduction of energy.

Conversion of hazardous materials using supercritical water oxidation

Patent Rofer, Cheryl K [Los Alamos, NM]; Buelow, Steven J [Los Alamos, NM]; Dyer, Richard B [Los Alamos, NM]; ...

A process for destruction of hazardous materials in a medium of supercritical water without the addition of an oxidant material. The harzardous material is converted to simple compounds which are relatively benign or easily treatable to yield materials which can be discharged into the environment. Treatment agents may be added to the reactants in order to bind certain materials, such as chlorine, in the form of salts or to otherwise facilitate the destruction reactions.

Method and apparatus for waste destruction using supercritical water oxidation

Patent Haroldsen, Brent Lowell [1251 Sprague St., Manteca, CA 95336]; Wu, Benjamin Chiau-pin [2270 Goldenrod La., San Ramon, CA 94583]

The invention relates to an improved apparatus and method for initiating and sustaining an oxidation reaction. A hazardous waste, is introduced into a reaction zone within a pressurized containment vessel. An oxidizer, preferably hydrogen peroxide, is mixed with a carrier fluid, preferably water, and the mixture is heated until the fluid achieves supercritical conditions of temperature and pressure. The heating means comprise cartridge heaters placed in closed-end tubes extending into the center region of the pressure vessel along the reactor longitudinal axis. A cooling jacket surrounds the pressure vessel to remove excess heat at the walls. Heating and cooling themore » « less
