  • CHEMICAL COMPOUNDS: SODIUM SULPHITE [Na2SO3]

    Oct 09, 2017 · Sodium sulfite is primarily used in the pulp and paper industry.It is used in water treatment as an oxygen scavenger agent, to treat water being fed to steam boilers to avoid corrosion problems, [2] in the photographic industry to protect developer solutions from oxidation and (as hypo clear solution) to wash fixer (sodium thiosulfate) from film and photo-paper emulsions, in the textile Learn More

  • PROPER BOILER LAY-UP PROCEDURES - bondwater.com

    sodium sulfite (Na2SO3) may be pumped into the boiler either separately, or along with the alkali solution referred to above, to react with and remove the dissolved oxygen. In most cases, sufficient sodium sulfite would be fed to maintain a reservoir of at least 100 ppm sodium sulfite (Na2SO3).Learn More

  • 7.0 Chemical Treatment - Steam Turbine, Steam Boiler

    A sulfite residual should be maintained in the boiler of about 5 to 20 mg/L as SO 3. The feed rate should be that shown in Table 3-5 plus 5 to 20 mg/L as sulfite divided by the boiler cycles. Although sulfite reacts slowly with oxygen at room temperature, it reacts very quickly at elevated temperatures. Also, the presence of minute quantities ofLearn More

  • Technical Performance Chemicals Product Hydrazine

    Sodium sulfite contributes dissolved solids (sodium sulfate) to the boiler water. It decomposes into corrosive products above 282 °C (540 °F), which corresponds to about 950 psig of saturated steam. Comparatively large residuals of sodium sulfite are required to form and maintain the magnetite barrier which protects steel surfaces.Learn More

  • Boiler Water Treatment Chemicals, Feed, and Control

    12. Boiler room layout and number of boilers. The dosage of sodium sulfite or other oxygen scavengers may be calculated by looking at their reaction rate to remove the oxygen and then their residual dosage to provide a feedwater or boiler water residual. Sodium Sulfite Example The reaction rate is: 2Na 2SO 3 (7.88 ppm) + O 2 ( 1 ppm) o 2Na 2SO 4Learn More

  • Boiler Feedwater Treatment - WaterCore

    The most common Oxygen scavenger is Sodium Sulphite (Na2SO3), with an approximate dosing of 8 to 10 ppm per 1 ppm of dissolved Oxygen. Liquid catalysed Sodium Sulphite has a typical 45% concentration, so the economies of pre-heating the feed water are quite obvious.Learn More

  • Deaeration Systems - Sewage Treatment - Reverse Osmosis

    Oxygen scavenging chemicals are very often added to the deaerated boiler feedwater to remove any last traces of oxygen that were not removed by the deaerator. The most commonly used oxygen scavenger is sodium sulfite (Na2SO3). It is very effective and rapidly reacts with traces of oxygen to form sodium sulfate (Na2SO4) which is non-scaling.Learn More

  • Sodium Sulphite (sulfite) with Catalyst Powder | Marine

    Removal of oxygen using commercial sodium sulfite and a catalyzed sodium sulfite makes great difference . After 25 seconds of contact, catalyzed sodium sulfite removed the oxygen completely. Uncatalyzed sodium sulfite removed less than 50% of the oxygen in this same time period. In a boiler …Learn More
