Abstract
The invention relates to a technical sodium purification method consisting of placing liquid sodium in contact at a temperature greater than or equal to 150° C., inside a static mixer, with an inert gas stream with respect to the sodium containing the stoechiometric quantity of water vapour required to oxidise calcium so as to lower its content to the desired content, and then separating the purified sodium from the inert gas, and the hydrogen and lime produced by the reaction.
