The technology used by the new SG 20 plant is completely different from the other existing plants. In particular, the technology exploits a natural phenomenon related to concentric crystallographic growth starting from a sulfur seed produced inside the plant, the sulfur is sprayed inside a tank where it instantly solidifies, and then continue its path inside a rotating tube that at regular intervals increases the diameter of the seed through nozzles that spray the seeds making it take on a spherical shape, recognized by the SUDIC specification.
