Sulphur Processing

Sulphur Melting and Purification

Sulphurnet has focused its activities on the Design and Manufacturing of liquid sulphur melting and purification plants. We engineer complete Sulphur melting and filtration systems to the strictest production and environmental requirements, with a typical turnkey project covering the entire process from the Solid Sulphur Feeding conveyors, up to the clean sulphur storage tank.

Our activities range from the FEED (front-end engineering design) to the manufacturing and start-up of the plant. Sulphurnet delivers turnkey solutions for sulphur melting and purification, including utility equipment and control systems.

The Process

The typical Sulphurnet sulphur melting and filtration process starts in the solid sulphur handling section, where solid sulphur gets loaded on a conveyor belt and gets neutralised by adding lime.  

Using the conveyor belt the solid sulphur is transported to the liquid sulphur melting tank, where the sulphur is heated until it’s melting point to form liquid sulphur. 

Whereafter the Liquid Sulphur flow from the Melting tank into the dirty sulphur tank from where it is pumped to the liquid sulphur filter. Inside of the liquid sulphur filter, solid particles are removed from the liquid sulphur. Additionally, a liquid sulphur polishing filter can be installed after the liquid sulphur filter to remove even finer particles and to act as a safety filter. 

The now clean liquid sulphur is stored in the liquid sulphur storage tank from where it can be used by other processes requiring clean liquid sulphur.

Liquid Sulphur

Melting Tank

Sulphurnet Sulphur Melters are above-ground tanks with steam coils which provide the energy required for melting solid sulphur.

The tank comes equipped with a conical bottom with the ability to drain without stopping the tank operation, is executed with internal brick lining for corrosion prevention and is fitted with an agitator to increase melting efficiency.

The main advantages of using a Sulphurnet Sulphur Melter are:

  • Better Heat Transfer
  • Less settling
  • Continuous Operation because heavy solids will remain in the melting tank
  • No need to shut down for cleaning
  • Less down time and less Sulphur wasted

Filtration

At the heart of every Liquid sulphur melting and purification plant one ore more liquid sulphur filters ore strainers are installed to remove contaminants such as ash, bitumen and organics from the liquid sulphur. Sulphurnet offers the following jacketed filtration systems for liquid sulphur:

  • Liquid Sulphur Filter (Pressure Leaf type)
  • Liquid Sulphur Self Cleaning Candle Filter
  • Liquid Sulphur Polishing Filter
  • Liquid Sulphur Strainer

Sulphur Prilling

Sulphurnet collaborates with Kreber in the development of equipment to create High Quality Sulphur Prills.

Sulphur prills in bulk offers significant advantages:

  • Excellent ‘free flowing’ properties
  • Low tendency to stick and agglomerate
  • Distinguished for air lifting
  • Highly resistant to abrasion or damage
  • Minimal dust formation
  • Well suited for transportation in road tankers, containers and big bags
  • Excellently storable in silo installations
  • Precise dosage
  • No additives needed; pure materials
