Abstract: PROBLEM TO BE SOLVED: To provide a method for preparing an anhydrous alkali metal sulfide which forms a particulate product and no dust and performs better heat exchange or matter exchange compared to that in conventional methods.
SOLUTION: In the preparation method for the anhydrous alkali metal sulfide, a hydrated alkali metal sulfide is dried through fluidized bed spray granulation.

Abstract: Production of anhydrous alkali metal sulfides comprises spray drying an alkali metal sulfide, suspension, dispersion or melt with a mixture of steam and inert gas. An Independent claim is also included for apparatus for carrying out the above process, comprising a drying chamber equipped with an atomizer, a drying gas inlet, a waste gas outlet, a solid separation system connected to the outlet and comprising a waste gas discharge pipe optionally including a filter, a unit for solvent recovery from the waste gas, and equipment for recycling and conditioning the waste gas for re-use as drying gas.
