Sodium Hydrosulfite Production Line/ Sodium dithionite production Line

Product Description Sodium hydrosulfite production line, Use Sulfur, Air, Soda ash (Na2 CO3, Sodium carbonate), Caustic soda (NaOH, Sodium hydroxide), Sodium Formate, Methanol, Ethylene epoxide as raw material, to produce Sodium Hydrosulfite product. We can provide the advantaged technolgy, detail engineering design, equipment, and provide installation and training, to ensure the plant successful operation as design parameters.                                                                                                                           Product:                   Sodium Hydrosulfite(Na2S2O4)  Molecular formula:Na2S2O4 Quality standard:    HG/T2967-2110   Raw materials: Sulfur, Air, Soda ash (Na2 CO3, Sodium carbonate), Caustic soda (NaOH, Sodium hydroxide), Sodium Formate, Methanol, Ethylene epoxide   Our Services Provide Technology Package and Turn-key project. which including: 1) Provide technology transfer; 2) Provide detail engineering design; 3) Provide complete sets of equipment, instrument, installation materials; 4) provide installation guidance or installation service; 5) Provide technical training. 6) Provideequipment debugging and trail production.   Advantages 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)The sodium hydrosulfite plant adopts well-developed process, so the products quality is very good and stabile.   7)The drying equipment was improved (patent equipment), with high safety. the plant adopts well-developed synthesis reaction, preparation, and neutralization reaction equipment (special equipment), it's  operation stable, and improve raw material yield.   8)Recovery of sodium formate from distillation residue, and re-used for sodium hydrosulfite production, improved raw material yield and reduced pollution emissions.   9) Recycling condensed water of distillation residue concentration, reducing the amount of wastewater discharge,  SO2 concentration in waste gas is less than 100mg/Nm3 (SO2 ≤ 100mg/Nm3)   10)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.   11)Details sufficient consideration, perfect and practical design.
