Molten Liquid Sulfur vs Solid Sulfur: Logistics, Thermal Storage & Economic Evaluation
Molten sulfur (CAS 7704-34-9) is transported in steam-jacketed pipelines, railcars, and specialized heated tank vessels strictly within the 135 deg C to 145 deg C thermal window to maintain 7–9 cP viscosity. While liquid delivery eliminates port dust and remelting costs, solid granular sulfur dominates intercontinental ocean trade.
