Testing methods for residual ammonia water
Thread Content
Testing methods for residual ammonia water: Determination of the total ammonia content in residual ammonia water, determination of the hydrogen cyanide content in residual ammonia water, determination of the pyridine content in residual ammonia water.
Analysis method for ammonia gas after the ammonia vapor fractionator in the ammonia vaporization tower: The analysis parameters include ammonia content, pyridine content, and hydrogen cyanide content. Urgently need to resolve this, thanks!
It is the excess ammonia water from the coking industry; the excess ammonia water in our plant comes from mechanical clarification tanks. In the book on coking chemical products, it is stated that the ammonia content in the residual ammonia water is around 4 g/l, whereas the results obtained by our factory’s laboratory are between 8 and 9 g/l. I wonder if this is possible, or whether an incorrect analysis method was used, resulting in such a large discrepancy? Our factory has only tested the ammonia content; hydrogen cyanide and pyridine have not been tested yet. These data are urgently needed for production, so we kindly ask experts for their assistance. Thank you very much!
Give the original poster a link that contains the relevant standards. Contact me if you have any questions; my area of expertise includes the testing of coking wastewater. http://bbs.hcbbs.com/thread-242473-1-1.html
