Title: Sodium purification apparatus and method

Abstract

An apparatus for and method of collecting and storing oxide impurities contained in high-temperature liquid alkali metal are disclosed. A method and apparatus are provided for nucleating and precipitating oxide impurities by cooling, wherein the nucleation and precipitation are enhanced by causing a substantial increase in pressure drop and corresponding change in the velocity head of the alkali metal. Thereafter the liquid alkali metal is introduced into a quiescent zone wherein the liquid velocity is maintained below a specific maximum whereby it is possible to obtain high oxide removal efficiencies without the necessity of a mesh or filter. 1 fig.
