ABSTRACT:
Disclosed herein are various types of systems and methods for the efficient production of sulfur from a sulfur-laden gas. The system described herein includes a desulfurization unit, a regenerator receiving sulfurized mass from the desulfurization unit, a sulfur recovery unit, a sulfur track in fluid communication with the regenerator and the sulfur recovery unit, and a sulfur concentrator on a sulfur track. The sulfur stream coming out of the regenerator is concentrated using the sulfur concentrator and converted into a sulfur product at the sulfur recovery unit.
