The Sulphurnet Sulfur Melting Tank

The very first step in the sulfur melting and purification process happens inside the sulfur melting tank. Inside this tank steam coils heat the solid sulphur until the melting point forms liquid sulphur. Besides this, the lime that is added to the solid sulfur on the conveyor belt reacts with the sulfuric acid to neutralize the acid and prevent corrosion later in the process.

Sulphurnet’s melting tanks are designed with a conical bottom including the ability to drain without stopping the liquid sulfur meter operation. The liquid sulfur melting tank comes equipped with internal brick lining for corrosion protection as well as a centrally mounted agitator that increases the melting velocity inside of the melting tank and keeps solid particles in suspension.

The main advantages of the Sulphurnet sulfur melting tanks are better heat transfer, less settling of solids, continuous operation, no need to shut down, and no manual cleaning which saves time and means less sulfur wasted.

Sulphurnet over the years has designed many liquid sulfur melting tanks for various design flows. Currently, the biggest Sulphurnet liquid sulfur melting tanks in the world are producing 70 metric tons per hour of liquid sulfur each.

Conti Melter

· Capacity 20 -100 Mton Sulphur melting per day*

· Internal heat exchanger. Replacement without process interruption

· Vigorously agitation to intensify the melting process.

· Including Dirty Sulphur Pumping section for further processing

· Corrosion protection, increased equipment lifetime

*The capacity is based 2% water content in the solid sulfur

Heating Coils

Sulphurnet Sulfur Melters come equipped with steam-heated heating elements which provide the energy required for melting the solid sulfur into liquid sulfur.

Unique to the Sulphurnet design is that we use coiled heating coils. Using coil-shaped heating coils reduces the number of potential leaks compared to conventional heating coils since the coil is formed out long pieces of piping which reduces the amount of welds / weak spots for corrosion. Besides this, these heating coils also allow for easy maintenance since they can be lifted straight out of the melting tank.

Sulfur Flash Melter

For applications where high impurities and high moisture contents are expected and where excessive Liquid Sulphur foaming happens in the liquid sulfur melting tank, Sulphurnet offers the Flash Sulphur Melter.

Inside of the Sulphurnet Flash Sulphur Melter solid sulfur containing water is quickly heated within the flash melter because of which most of the moisture inside of the solid sulfur will evaporate before entering the regular liquid sulfur melting tank.

The main benefits of the Sulphurnet Flash Sulphur Melter are:

Compact design (small plot space)
Increased capacity of existing melting plant
No moving parts, low maintenance cost
No internal coils, less corrosion
Can handle sulfur with high water contents
Suitable for powder type of sulfur
Less foaming issues
