A trip into molten sulfur
Lakes of molten sulfur are features sometimes found in seafloor hydrothermal vent systems. Daikoku of the northern Mariana Arc is notable for being home to one of such features inside its summit caldera, the "Sulfur Cauldron" discovered in 2006. A number of oceanographic research cruises since then have revealed significant …
Lop Nor, the Wandering Lake – Molten Sulfur Blog
The stable rivers supported agriculture and a kingdom and city called Loulan. Loulan controlled the oases along one of the major trade routes between China and the outside world. When Lop Nor started moving again, it meant the rivers could no longer be relied on to stay still and water the crops. The city of Loulan was abandoned in 330 A.D.

Fundamentals of Sulfur Recovery Presented at the
After a long haul, the sulfur has been agitated and cools to 280F allowing the contents to approach equilibrium as in Table 3. Assuming a 30 ton sulfur truck with 5% vapor volume is used, the H2S content in the tank truck vapor space at the end of the haul is 40.5% volume, which is within the flammable range.

Storage and Handling of Molten Sulfur. Many chemical process plants produce elemental sulfur from the collection of waste gases containing sulfur. The sulfur is generally stored in its molten state so that it can be more readily shipped to buyers. This can come with its own corrosion problems, as explained in the bulletin.
Sulfur
Thermal conductivity of Sulfur is 0.269 W/ (m·K). The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K. It is a measure of a substance's ability to transfer heat through a material by conduction. Note that Fourier's law applies for all matter ...
The rheology of liquid elemental sulfur across the λ-transition
Seventy million tons of sulfur were produced worldwide in 2016. Much of the transportation and handling of molten sulfur require sulfur pumps which are challenging to operate due to the anomalous behavior of sulfur's liquid viscosity at temperatures near its λ-transition region.Sulfur's viscosity decreases from ca. 30 × 10 −2 to ca. 7 × 10 −2 Pa s …

Characterization of sulphur particles: prills vs. granules
Following a patent by, Campbell (Citation 1967), molten sulfur is pumped via trays and then decanted in droplet form into a water bath which is constantly moving. Through this wet prilling process, sulfur prills are formed when molten sulfur comes into contact with water.
Did You Know Volcanoes Can Erupt Molten Sulfur?
The yellow crust around steam vents (known as fumaroles) is evidence of sulfur crystallising out of gases and liquids at these volcanoes. There are some volcanoes around the globe that also create flows made of molten sulfur! So, instead of flows of molten rock we get rivers of liquid sulfur that can reach hundreds of feet.

Application Newsletter Molten Sulfur
Sulfur is a very poor conductor of heat, and is very difficult to reheat in piping once the temperature has dropped below 240 deg F. So temperature above that must be maintained. The most common material of construction for pipe, valves and pumps in sulfur service is steel or ductile iron. Pumps moving molten sulfur must be steam jacketed. Also ...
