The Operating Conditions of MSO Technology and its Effect on Construction Materials

Popis výsledku v původním jazyce

Molten Salt Oxidation (MSO) is a technology of flameless oxidation in molten salts materials to reduce the volume of hazardous solid and liquid waste. It is an alternative to conventional combustion. Halogens and other substances (e.g., sulfides) are converted to acid gases and are captured in salt form (e.g., NaCl, Na2SO4). The technology allows processing of loose materials, semi-liquid suspensions or liquids over a wide range of viscosity. Combustible waste is fed through the dosing system into the reactor together with an oxidizing agent (air or oxygen). The oxidation process is deliberately taking place under the salt melt and heavy metals and radionuclides are captured within. This paper discusses the effect of MSO technology on construction materials of the MSO reactor vessel. MSO's operating conditions expose the construction materials to a highly corrosive effect: high temperature, corrosive alkaline melt components, and oxidation media. Experiments with selected materials were carried out in the laboratories of the Research Center Rez. The result was used to design a suitable building material for the reaction vessel MSO technology.
