Processing alkali metal-sulfide or alkali earth metal-sulfide to obtain the alkali metal or alkali earth metal

A method, comprising:

• providing a first conversion vessel;
• providing a process fluid;
• applying a sufficient quantity of an Alkali metal to the process fluid at a location disposed prior to the first conversion vessel to chemically bind the Alkali metal with an undesired element carried in the process fluid to strip the undesired element from the process fluid resulting in a clean fluid product and a first intermediary compound comprising the undesired element;
• introducing a first quantity of the first intermediary compound into the first conversion vessel;
• applying an Alkaline earth metal to the first intermediary compound in the first conversion vessel to chemically bind the Alkaline earth metal with the undesired element carried in the first intermediary compound effective to form a second intermediary compound and thereby, to strip the undesired element from the first intermediary compound;
• extracting the Alkali metal from the first conversion vessel;
• recycling the Alkali metal from the first conversion vessel for application of recovered Alkali metal to clean additional process fluid at the location;
• extracting the second intermediary compound from the first conversion vessel;
• processing the second intermediary compound in a process loop to recover at least the Alkaline earth metal;
• wherein the process loop comprises
• providing a second conversion vessel;
• introducing an effective Halogen into the second conversion vessel to react with the second intermediary compound in the second conversion vessel to separate the undesired element from the second intermediary compound and form a third intermediary compound comprising an Alkaline Earth Metal Halide;
• extracting the undesired element from the second conversion vessel;
• extracting the third intermediary compound from the second conversion vessel;
• processing the third intermediary compound in a third conversion vessel to recover at least the Alkaline earth metal;
• and
• introducing recovered Alkaline earth metal from the third conversion vessel into the first conversion vessel.

A method, comprising:

• providing a reaction vessel and a first conversion vessel;
• introducing a process fluid into the reaction vessel;
• applying an Alkali metal to the process fluid in the reaction vessel to react with Sulfur in the process fluid and form an Alkali metal sulfide
• removing the Alkali metal sulfide from the reaction vessel and introducing the Alkali metal sulfide into the first conversion vessel;
• applying an Alkaline earth metal to the Alkali metal sulfide in the first conversion vessel to form an Alkaline earth metal sulfide and to permit recovery of the Alkali metal for recycled use of the Alkali metal in the reaction vessel;
• removing the Alkaline earth metal sulfide from the first conversion vessel and introducing the Alkaline earth metal sulfide into a second conversion vessel;
• introducing a Halogen into the second conversion vessel to separate the Sulfur from the Alkaline earth metal sulfide and to form an Alkaline earth metal halide;
• removing the Sulfur from the second conversion vessel;
• removing the Alkaline earth metal halide from the second conversion vessel;
• and
• processing the Alkaline earth metal halide in an electrolytic cell to recover the Alkaline earth metal for recycled use in the first conversion vessel and to recover the Halogen for recycled use in the second conversion vessel.
