Whereafter the Liquid Sulfur flows from the Melting tank into the dirty sulfur tank from where it is pumped to the liquid sulfur filter. Inside the liquid sulfur filter, solid particles are removed from the liquid sulfur. Additionally, a liquid sulfur polishing filter can be installed after the liquid sulfur filter to remove even finer particles and act as a safety filter.
The now clean liquid sulfur is stored in the liquid sulfur storage tank from where it can be used by other processes requiring clean liquid sulfur.
