The very first step in the sulphur melting and purification process happens inside of the sulphur melting tank. Inside of this tank steam coils heats the solid sulphur until the melting point to form liquid sulphur. Besides this, the lime that is added to the solid sulphur on the conveyor belt is reacting with the sulphuric acid to neutralize the acid and prevent corrosion later in the process.
The Sulphurnet melting tanks are designed with a conical bottom including the ability to drain without stopping the liquid sulphur meters operation. The liquid sulphur melting tank comes equipped with internal brick lining for corrosion protection as well as a centrally mounted agitator that increase the melting velocity inside of the melting tank and keeps solid particles into suspension.
The main advantages of the Sulphurnet sulphur 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 sulphur wasted.
Sulphurnet over the years has designed many liquid sulphur melting tanks for various design flows. Currently, the biggest Sulphurnet liquid sulphur melting tanks in the world are producing 70 metric tons per hour of liquid sulphur each.
Sulphurnet Sulphur Melters come equipped with steam-heated heating elements which provide the energy required for melting the solid sulphur into liquid sulphur.
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.
For applications where high impurities and high moisture contents are expected and where excessive Liquid Sulphur foaming happens in the liquid sulphur melting tank, Sulphurnet offers the Flash Sulphur Melter.
Inside of the Sulphurnet Flash Sulphur Melter solid sulphur containing water is quickly heated within the flash melter because of which most of the moisture inside of the solid sulphur will evaporate before entering the regular liquid sulphur melting tank.
The main benefits of the Sulphurnet Flash Sulphur Melter are:
Sulphurnet understands the importance of providing clients with the highest quality of design, documentation and project management services and we strive to maintain project schedules.
