    Initially, a volume of 150ml of MARZINE-PLUS per ton of water must be used, depending on operating pres-sure and on the system's layout. Thereafter, everyday testing of hydrazine in the boiler water, with the use of MARICHEM HYDRAZINE TEST KIT, will determine the daily dosage to maintain the concentration within the desired levels.Learn More

  • DESCRIPTION - Ertek Chemicals

    For 0-40 atm boiler pressure 20-40 ppm phosphate is sufficient. For 40-60 atm 20-30 ppm phosphate is sufficient. For >60 atm boilers 5-10 ppm of phosphate is sufficient and provides efficient protection. HYDRAZINE TEST: Hydrazine is used in the boiler as oxygen scavenger and corrosion inhibitor. In low pressure boilers (0-20 atm), 0.1-0.3 ppm Learn More

  • 25 ppm of hydrazine in 25 tons boiler - rota-form.de

    Jul 05, 1992 · The boiler parts are filled with DM water containing 300-500 ppm hydrazine and a indicates the variation of hydrazine level in boiler #66 during this period. Despite 25 and 40% of the original hydrazine was found to have decomposed after 30 and 60 days, respectively.Learn More

  • Volatile Corrosion Inhibitors and Boiler Water Additives

    As a general rule, sodium sulfite can be safely used as an oxygen scavenger in boilers working at pressures up to at least 1,000 lb/in2, provided that the boiler water is alkaline and the con- centration of sulfite is not above about 10 ppm (Na2S03). Hydrazine-- Hydrazine is a powerful reducing agent which reacts with dissolved oxygen under Learn More

    Other chemicals added to the boiler water include hydrazine for oxygen scavenging, and small amounts of ammonia for pH control. Hydrazine is stored in 55 gallon drums at the KFGS. A hand pump is installed in the drum and piped into the day tank where it is diluted and pumped as needed.Learn More

  • Automated process for inhibiting corrosion in an inactive

    The boiler has a capacity of 5–9 tons. The amount of hydrazine to obtain a minimum amount of hydrazine, equivalent to 200 ppm, is calculated as follows: Assume there are 8 ppm oxygen in the water at ambient temperature. The amount of hydrazine needed to maintain a residual of 200 ppm hydrazine is 8+200=208 ppm hydrazine. 6 =1.04 Kg hydrazine.Learn More

  • Hydrazine VACUettes Kit, Range: 0-25 ppm

  • Highly sensitive determination of hydrazine ion by ion

    Jun 11, 2004 · The calibration graph of hydrazine ion detected as H 2 SO 4 was linear over the concentration range of 0.001–100 ppm (r 2 =0.9988). The detection limit of hydrazine ion in this system was 0.64 ppb. Therefore, hydrazine ion in real boiler water sample could be accurately determined, avoiding the interference of other cations.Learn More

  • Reagent and method for the determination of hydrazine

    Hydrazine is a known anti-corrosive agent for steel in contact with water, for example, in steam boiler operation, in warm water circulation systems and in the shut-down preservation of vessels and the like. Depending on the temperature and pressure conditions, 0.1-300 ppm of hydrazine are added to the water.Learn More
