What is Molten Sulphur?

Sulphur is one of the most versatile elements in the world and is significantly used in the chemical and fertiliser industries in the form of sulphuric acid.

There are many forms of Sulphur depending on the ash and carbon concentration, such as Frash, floatation, bright, near bright, dark, and Claus.

Why Filter Molten Sulphur?

Filtration of molten sulphur is key to achieving the desired properties and performance required for a specific process. Main goals of molten sulphur filtration are as follows:

  • Removal of solids (ash, dust, dirt, organics) to avoid process problems and to ensure longer operating periods between maintenance
  • Eliminating blockage in reactor tubes used for in the production of carbon-disulphide
  • Further purification and quality improvement of mined flotation processed Sulphur
  • Lowering pH value to diminish chance of corrosion
