Abstract
A system for removing contaminant from sulfur to a level that allows re-processed sulfur to reenter a supply chain. The system melts contaminated sulfur, filters the molten sulfur, and then dispenses the less contaminated sulfur after filtering it. More specifically, solid contaminated sulfur enters a settling tank, while heated molten sulfur circulates through the system and the settling tank. The circulation of the molten sulfur assists in the melting process of the solid sulfur, allowing the solid sulfur to melt efficiently. In preferred embodiments of the system, the system uses steam jacked sulfur lines and steam tracing to maintain temperatures for melting the solid sulfur and maintaining the molten state of the sulfur circulating through the system. Furthermore, the system comprises a programmable logic controller, which controls motors, pumps, valves, and environment monitoring instruments.
