Ammonia concentration?
Thread Content
I would like to ask the experts: what is the concentration of ammonia water in the coking cycle, what is the concentration of concentrated ammonia water used in vaporization, and what is the maximum concentration of ammonia water suitable for industrial use?
An ammonia leak detector is needed; please call 0531-68658651 or 15376412556 (WeChat available as well)
Circulating ammonia water: 4–5%.. Ammonia vapor: 13% – from our factory.
The total ammonia concentration in the circulating ammonia water is 2–5 g/L (0.2–0.5%). The sister unit upstairs made a mistake!
The concentration of concentrated ammonia used in ammonia vaporization is a bit complex; it is designed to be between 18% and 20%, but in actual factory production the concentration is usually lower than that
What is the maximum concentration of ammonia water for industrial use? This question is rather vague and cannot be answered.
Ammonia content in wastewater after ammonia evaporation: ≤200 mg/L; concentration of concentrated ammonia solution: 10–12%
