What is the hydrogen sulfide content in liquid ammonia?
Thread Content
Just after renewing the high-pressure vessel manufacturing certificate, one of the corrective actions required was to specify the hydrogen sulfide content on the drawings of the liquid ammonia storage tanks. Dear sea friends, does anyone know the hydrogen sulfide content in liquid ammonia? Please share your knowledge; thank you!
Liquid ammonia generally does not contain hydrogen sulfide...
What process is used to produce liquid ammonia? The total sulfur content in the liquid ammonia produced by the wastewater stripping unit is normally only a few ppm.
It means these experts’ brains have been screwed by donkeys~~~
In the process of producing synthetic ammonia from natural gas, hydrogen sulfide must be removed before it enters the conversion furnace; therefore, hydrogen sulfide should not be considered in the medium within the liquid ammonia storage tanks of this system. The other processes are not clear; it is recommended to ask the design institute or the owner’s process engineer.
I’ve learned that the drawings of liquid ammonia storage tanks require indication of either the ammonia concentration or the water content: victory:
The liquid ammonia obtained from the acidic water stripping unit will contain hydrogen sulfide； I’m asking out of curiosity: what methods are used to test for hydrogen sulfide in liquid ammonia?
