The invention relates to a process for recovering the sulfur components of acidic gases collected by gas desulfurization. The inventive concept is to first compress a stream of the acidic gas (known as "acid gas") up to a pressure of 8.00 to 12.00 atmospheres absolute. Then this compressed stream of gas is cooled to -35 DEG to -45 DEG C. The pressure on this cooled gas is reduced to a pressure of 1.05 to 2.00 atmospheres absolute. Subsequently, the gas is further cooled to a temperature of -55 DEG to -65 DEG C. Finally, the resulting mixture is conducted to a separator where frozen solid constituents are separated from the gaseous constituents. The gaseous constituents include substantially all of the sulfides produced during the gas desulfurization and the frozen solid particles consist essentially of carbon dioxide.
