Ph And Phosphate Concentration In Bfw And Steam

Keep dosing rate between 0,2-0,5ppm. Keep Dissolved O2 below 6 ppb( on line measurement) ii. Use volatile alkali ( for example amine:Nalco's Triact-1800 ) for pH control.Don't use ammoniacal water as it would increase the conductivity and so losses due to higher blow down. Dosing rate should be based on pH indication by online pH meter. BB.

Boiler Treatment Chemicals - DEHA - Diethyl Hydroxyl

It is the precursor to sulfenamide-based reagents used as accelerators for vulcanization. It is a building block for pharmaceuticals (e.g., mucolytics, analgesics, and bronchodilators). The amine itself is an effective corrosion inhibitor. Some sweeteners are derived from this amine, notably cyclamate.

Water Handbook - Condensate System Corrosion | SUEZ

2  · In Figure 19-5, the recycle factor is the concentration of amine at point x divided by the amine feed rate at point z. Because some amine is returned with the condensate, the total amine in the system is greater than the amount being fed. Recovery ratio is a measure of the amount of amine being returned with the condensate. It is calculated as
