Sulfur, Air, Soda ash (Na2 CO3, Sodium carbonate), Caustic soda (NaOH, Sodium hydroxide)
2, Characteristics of Sodium hydrosulfite production technology:
1)Using the world's advanced sulfur excess air incineration process, the obtained sulfur dioxide gas concentration is high (SO2%≥20.5%). The sulfur furnace running temperatures is low (500-600℃), has good stability and high safety.
2)Using chemical process removal of sublimed sulfur, the sublimed sulfur is removal thoroughly, so the sulfur dioxide gas purity is high, the final product has good quality.
3)Sulfur dioxide production process more secure, more energy saving.
4)Perfect heat recycles design. Recycle of sulfur burning heat and obtained steam, the steam is used in the production. The design great reduced the cost of steam supply of production.
5)Improve the degree of automation, control precision and stabile
6)Perfect water recovery system, no process waste water discharge.
7)Years of proven experience in establish sodium hydrosulfite plant, we ensure establish of the plant will fast and successful, and we ensure the plant once successful start-up.
8)Details sufficient consideration, perfect and practical design.
