Abstract

Methods, systems, and apparatus for managing sulfur are disclosed. In some embodiments, the method comprise the following: obtaining material containing sulfur; refining the material to develop a high sulfur content heavy fraction fuel oil and a low sulfur content light fraction fuel oil; burning the low sulfur content light fraction fuel oil in apparatus that emit to the atmosphere; burning the high sulfur content heavy fraction fuel oil to produce energy thereby generating flue gas containing sulfur oxide; and removing and disposing of sulfur in the flue gas using a sulfur sequestration system that includes utilizing sulfur removed from the flue gas to form a brine material.
