Abstract: During the production process of sulfur wet forming machine in Puguang Natural Gas Purification Plant, sulfur particle products would be finished together with a large amount of fine sulfur powder. Since the particle size of the fine sulfur powder was very small and easy to be enriched in the circulating water of the forming process, which would be due to the issues like plugging of vibrating screen, water tank, and cooling tower packing. In the meantime, water content of sulfur products would increase as well. The liquid sulfur wet forming process was simulated by experiment. The results showed that forming plates aperture and height of liquid sulfur into the water were key influencing factors of the generation rate of fine powder sulfur. When the forming plate aperture was 2.1 mm and the height of liquid sulfur into the water was 2 cm, the generation rate of fine powder sulfur was the lowest, which could provide reference for reducing the generation rate of fine powder sulfur in the process of the similar domestic sulfur wet molding unit.
