ABSTRACT:
The method of removing sulfurous compounds (organic and inorganic) from any fluid (gas or liquid) phase by contacting said fluid (gas or liquid) with the reactive metal to form a metal sulfide recovering said fluid (gas or liquid) free from said sulfurous compound and containing compounds free from sulfur and recovering electrochemically said reactive metal from said sulfur to return said metal to elemental form to release elemental sulfur, said separating being done at temperatures above melting point of sulfur.
